Note 1 - Summary of Operations and Significant Accounting Policies	12 Months Ended
	Dec. 31, 2013
Accounting Policies [Abstract]	'
Organization, Consolidation, Basis of Presentation, Business Description and Accounting Policies [Text Block]	'
	Note 1 - Summary of Operations and Significant Accounting Policies
	a.             Description of Business
	We offer products and services ranging from portable power solutions to communications and electronics systems.  Through our engineering and collaborative approach to problem solving, we serve government, defense and commercial customers across the globe.  We design, manufacture, install and maintain power and communications systems including: rechargeable and non-rechargeable batteries, charging systems, communications and electronics systems and accessories, and custom engineered systems.  We sell our products worldwide through a variety of trade channels, including original equipment manufacturers (“OEMs”), industrial and defense supply distributors, and directly to U.S. and international defense departments.
	b.             Principles of Consolidation
	The consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States and include the accounts of Ultralife Corporation, our wholly-owned subsidiaries, Ultralife Batteries (UK) Ltd. (“Ultralife UK”), ABLE New Energy Co., Limited, and its wholly-owned subsidiary ABLE New Energy Co., Ltd. (“ABLE” collectively), and our majority-owned subsidiary Ultralife Batteries India Private Limited (“India JV”).  Intercompany accounts and transactions have been eliminated in consolidation.
	Operations of RedBlack Communications, Inc. (“RedBlack”), our divested company and certain components of UK operations are reported as discontinued operations.
	c.             Management's Use of Judgment and Estimates
	The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at year end and the reported amounts of revenues and expenses during the reporting period.   Key areas affected by estimates include: (a) reserves for deferred tax assets, excess and obsolete inventory, warranties, and bad debts; (b) profitability on development contracts; (c) various expense accruals; (d) stock-based compensation; and, (e) carrying value of goodwill and intangible assets.  Our actual results could differ from these estimates.
	d.             Reclassifications
	Certain items previously reported in specific financial statement captions have been reclassified to conform to the current presentation.
	e.             Cash and Cash Equivalents
	For purposes of the Consolidated Statements of Cash Flows, we consider all demand deposits with financial institutions and financial instruments with original maturities of three months or less to be cash equivalents.  For purposes of the Consolidated Balance Sheet, the carrying value approximates fair value because of the short maturity of these instruments.
	Our cash balances may at times exceed federally insured limits.  We have not experienced any losses in these accounts and believe we are not exposed to any significant risk with respect to cash and cash equivalents.
	f.             Accounts Receivable and Allowance for Doubtful Accounts
	We extend credit to our customers in the normal course of business. We perform ongoing credit evaluations and generally do not require collateral.  Trade accounts receivable are recorded at their invoiced amounts, net of allowance for doubtful accounts.  We evaluate the adequacy of our allowance for doubtful accounts quarterly.  Accounts outstanding longer than contractual payment terms are considered past due and are reviewed individually for collectability.  We maintain reserves for potential credit losses based upon our loss history and specific receivables aging analysis. Receivable balances are written off when collection is deemed unlikely.
	Changes in our allowance for doubtful accounts during the years ended December 31, 2013 and 2012 were as follows:
			2013			2012
	Balance at beginning of year		$	322		$	683
	Amounts charged to expense			29			9
	Uncollectible accounts written-off, net of recovery			(63	)		(370	)
	Balance at end of year		$	288		$	322
	The significant uncollectible accounts written off in 2012 relate to previously recorded bad debts of our now discontinued Energy Services business.
	g.             Inventories
	Inventories are stated at the lower of cost or market with cost determined under the first-in, first-out (FIFO) method.  We record provisions for excess, obsolete or slow-moving inventory based on changes in customer demand, technology developments or other economic factors.
	h.             Property, Plant and Equipment
	Property, plant and equipment are stated at cost.  Estimated useful lives are as follows:
	Buildings (years)		10	–	20
	Machinery and Equipment (years)		5	–	10
	Furniture and Fixtures (years)		3	–	10
	Computer Hardware and Software (years)		3	–	5
	Leasehold Improvements		Lesser of useful life or lease term
	Depreciation and amortization are computed using the straight-line method.  Betterments, renewals and extraordinary repairs that extend the life of the assets are capitalized.  Other repairs and maintenance costs are expensed when incurred.  When disposed, the cost and accumulated depreciation applicable to assets retired are removed from the accounts and the gain or loss on disposition is recognized in operating income (expense).
	i.               Long-Lived Assets, Goodwill and Intangibles
	We regularly assess all of our long-lived assets for impairment when events or circumstances indicate that their carrying amounts may not be recoverable.  For property, plant and equipment and amortizable intangible assets, this is accomplished by comparing the expected undiscounted future cash flows of the assets with the respective carrying amount as of the date of assessment.  Should aggregate future cash flows be less than the carrying value, a write-down would be required, measured as the difference between the carrying value and the fair value of the asset. Fair value is estimated either through the assistance of an independent valuation or as the present value of expected discounted future cash flows.  The discount rate used by us in our evaluation approximates our weighted average cost of capital.  If the expected undiscounted future cash flows exceed the respective carrying amount as of the date of assessment, no impairment is recognized.  We did not record any material impairments of long-lived assets in the years ended December 31, 2013 or 2012.
	In accordance with the Financial Accounting Standards Board’s (“FASB”) guidance for goodwill and other intangible assets, we do not amortize goodwill and intangible assets with indefinite lives, but instead measure these assets for impairment at least annually, or when events indicate that impairment exists. We amortize intangible assets that have definite lives so that the economic benefits of the intangible assets are being utilized over their weighted-average estimated useful life.
	The impairment analysis of goodwill consists first of a review of various qualitative factors of the identified reporting units to determine whether it is more likely than not that the fair value of a reporting unit exceeds its carrying amount, including goodwill. This review includes, but is not limited to, an evaluation of the macroeconomic, industry or market, and cost factors relevant to the reporting unit as well as financial performance and entity or reporting unit events that may affect the value of the reporting unit. If this review leads to the determination that it is more likely than not that the fair value of the reporting unit is greater than its carrying amount, further impairment testing is not required. However, if this review cannot support a conclusion that it is more likely than not that the fair value of the reporting unit is greater than its carrying amount, or at our discretion, quantitative impairment steps are performed. Similarly, the analysis for indefinite-lived intangible assets consists of review of various qualitative factors to determine if it is more likely than not that the indefinite-lived intangible asset is not impaired.  If a conclusion that it is more likely than not that the indefinite-lived asset is not impaired cannot be supported, or at our discretion, quantitative impairment steps are performed.
	The quantitative impairment test for goodwill consists of a comparison of the fair value of the reporting unit with the carrying amount of the reporting unit to which it is assigned.  If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired.  If the carrying amount of a reporting unit exceeds its fair value, a second step of the goodwill impairment test shall be performed to measure the amount of impairment loss, if any.  The impairment test for intangible assets with indefinite lives consists of a comparison of the fair value of the intangible assets with their carrying amounts. If the carrying value of the intangible assets exceeds the fair value, an impairment loss shall be recognized in an amount equal to that excess.  We determine the fair value of the reporting unit for goodwill impairment testing based on a discounted cash flow model.  We determine the fair value of our intangibles assets with indefinite lives (trademarks) through the royalty relief income valuation approach.
	There were no impairments of goodwill and intangible assets with indefinite lives in the years ended December 31, 2013 and 2012.
	Based on the final valuations for amortizable intangible assets acquired in the AMTI acquisition during 2009, and the ABLE and McDowell acquisitions during 2006, we project our amortization expense will be approximately $309, $229, $167, $122, and $86 for the fiscal years ending December 31, 2014 through 2018, respectively.
	j.              Translation of Foreign Currency
	The financial statements of our foreign subsidiaries are translated into U.S. dollar equivalents in accordance with FASB’s guidance for foreign currency translation, with translation adjustments recorded as a component of accumulated other comprehensive income.  Exchange losses relate to foreign currency transactions included in net loss for the years ended December 31, 2013 and 2012 were $15 and $43, respectively.
	k.             Revenue Recognition
	Product Sales – In general, revenues from the sale of products are recognized when products are shipped. When products are shipped with terms that require transfer of title upon delivery at a customer’s location, revenues are recognized on the date of delivery.  A provision is made at the time the revenue is recognized for warranty costs expected to be incurred. Customers, including distributors, do not have a general right of return on products shipped.
	Technology Contracts – We recognize revenue using the proportional effort method based on the relationship of costs incurred to date to the total estimated cost to complete the contract. Elements of cost include direct material, labor and overhead.  If a loss on a contract is estimated, the full amount of the loss is recognized immediately.  We allocate costs to all technology contracts based upon actual costs incurred including an allocation of certain research and development costs incurred.
	Deferred Revenue – For each source of revenues, we defer recognition if: i) evidence of an agreement does not exist, ii) delivery or service has not occurred, iii) the selling price is not fixed or determinable, or iv) collectability is not reasonably assured.
	l.              Warranty Reserves
	We estimate future costs associated with expected product failure rates, material usage and service costs in the development of our warranty obligations.  Warranty reserves, included in other current liabilities and other long-term liabilities as applicable on our Consolidated Balance Sheets, are based on historical experience of warranty claims.  In the event the actual results of these items differ from the estimates, an adjustment to the warranty obligation would be recorded.
	m.             Shipping and Handling Costs
	Costs incurred by us related to shipping and handling are included in cost of products sold.  Amounts charged to customers pertaining to these costs are reflected as revenue.
	n.             Advertising Expenses
	Advertising costs are expensed as incurred and are included in selling, general and administrative expenses in the accompanying Consolidated Statements of Operations.  Such expenses amounted to $413 and $538 for the years ended December 31, 2013 and 2012.
	o.             Research and Development
	Research and development expenditures are charged to operations as incurred.  The majority of research and development expenses pertain to salaries and benefits, developmental supplies, depreciation and other contracted services.
	In 2011, we entered into a collaboration agreement with The New York State Energy Research and Development Authority (“NYSERDA”), to develop and demonstrate a large hybrid grid-connected energy storage system. This agreement was terminated by NYSERDA in the second quarter of 2013, per the terms of the agreement.  Pursuant to the terms of the agreement, NYSERDA reimbursed us for certain construction and project research and development costs.  During the year ended December 31, 2013, there were no recoveries from NYSERDA for construction costs and project research and development. During the year ended December 31, 2012, recoveries from NYSERDA for construction costs and project research and development costs were $91 and $11, respectively. Construction costs are reflected in the property, plant and equipment, net line on our Consolidated Balance Sheets and project research and development costs are reflected in the research and development line on our Consolidated Statements of Operations and Comprehensive Income (Loss).
	We plan to continue this project internally with smaller form batteries which provide greater opportunity and applicability in the markets we serve. However, due to the termination of the NYSERDA agreement and the resulting change in scope of the project, we performed a review of the details of costs capitalized in connection with this project to determine their future use. Those costs without an identifiable future use were written off in the second quarter of 2013 and totaled $56. The remaining capitalized costs were subjected to an impairment test based upon forecasted future cash flows, in accordance with current accounting guidance. No impairment charge was taken on the remaining capitalized costs.
	p.             Environmental Costs
	Environmental expenditures that relate to current operations are expensed or capitalized, as appropriate, in accordance with FASB’s guidance on environmental remediation liabilities.  Remediation costs that relate to an existing condition caused by past operations are accrued when it is probable that these costs will be incurred and can be reasonably estimated.
	q.             Income Taxes
	The asset and liability method, prescribed by FASB’s guidance for the Accounting for Income Taxes, is used in accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse.
	A valuation allowance is required when it is more likely than not that the recorded value of a deferred tax asset will not be realized.   As of December 31, 2013, we continue to recognize a valuation allowance in the U.S. and U.K. on our net U.S. deferred tax asset to the extent the differences and the U.S. and U.K. NOLs resulting in the deferred tax asset are not able to be offset by future reversing temporary differences, based on a consistent evaluation methodology that was used for 2012.  The assessment of the realizability of the U.S. NOL was based on a number of factors including, our history of net operating losses, the volatility of our earnings, our historical operating volatility, our historical inability to accurately forecast earnings for future periods and the continued uncertainty of the general business climate as of the end of 2013.   We concluded that these factors represent sufficient negative evidence and have concluded that we should record a full valuation allowance under FASB’s guidance on the accounting for income taxes.  We also recorded a valuation allowance on our net deferred tax asset for the year ended December 31, 2012.
	We have adopted the provisions of FASB’s guidance for the Accounting for Uncertainty in Income Taxes.  In 2013 and 2012, we had unrecognized tax benefits related to uncertain tax positions which have been recorded as a decrease in our NOL.  We have not recorded any interest or penalty in regard to any unrecognized benefit.  Interest and penalties would begin to accrue in the period in which the NOL’s related to the uncertain tax positions are utilized.  Our policy regarding interest and/or penalties related to income tax matters is to recognize such items as a component of income tax expense (benefit).
	r.              Concentration Related to Customers and Suppliers
	During the years ended December 31, 2013 and 2012, we had one major customer, a large defense primary contractor, which comprised 25% and 21% of our revenues, respectively.  There were no other customers that comprised greater than 10% of our total revenues during these years.
We have two customers who comprised 26% and 15%, respectively, of our trade accounts receivable as of December 31, 2013. We had two customers who comprised 22% and 12%, respectively, of our trade accounts receivable as of December 31, 2012.
Currently, we do not experience significant seasonal trends in our revenues.  Since a significant portion of our revenues are based on purchases from U.S. and allied country defense departments, the timing of our sales could be impacted by delays in the government budget process and the decisions to deploy resources to support military purchases of our products.
We generally do not distribute our products to a concentrated geographical area nor is there a significant concentration of credit risks arising from individuals or groups of customers engaged in similar activities, or who have similar economic characteristics. While direct and indirect sales to the U.S. Department of Defense have been substantial during 2013 and 2012, we do not consider this customer to be a significant credit risk.   We do not normally obtain collateral on trade accounts receivable.
Certain materials and components used in our products are available only from a single or a limited number of suppliers. As such, some materials and components could become in short supply resulting in limited availability and/or increased costs. Additionally, we may elect to develop relationships with a single or limited number of suppliers for materials and components that are otherwise generally available.  Although we believe that alternative suppliers are available to supply materials and components that could replace materials and components currently used and that, if necessary, we would be able to redesign our products to make use of such alternatives, any interruption in the supply from any supplier that serves as a sole source could delay product shipments and have a material adverse effect on our business, financial condition and results of operations.  We have experienced interruptions of product deliveries by sole source suppliers in the past.
s.             Fair Value Measurements and Disclosures
The FASB guidance for fair value measurements provides a framework for measuring fair value and requires expanded disclosures regarding fair value measurements. Fair value is defined as the price that would be received for an asset or the exit price that would be paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. This accounting standard established a fair value hierarchy, which requires an entity to maximize the use of observable inputs, where available. The following summarizes the three levels of inputs required.
Level 1:	Quoted prices in active markets for identical assets or liabilities.
Level 2:	Observable inputs, other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or that we corroborate with observable market data for substantially the full term of the related assets or liabilities.
Level 3:	Unobservable inputs supported by little or no market activity that are significant to the fair value of the assets or liabilities.
FASB’s guidance for the disclosure regarding fair value of financial instruments requires disclosure of an estimate of the fair value of certain financial instruments.  The fair value of financial instruments pursuant to FASB’s guidance for the disclosure regarding fair value of financial instruments approximated their carrying values at December 31, 2013 and 2012.  The fair value of cash, trade accounts receivable, trade accounts payable, accrued liabilities, and our revolving credit facility approximates carrying value due to the short-term nature of these instruments.  The estimated fair value of other long-term debt and capital lease obligations approximates carrying value due to the variable nature of the interest rates or the stated interest rates approximating current interest rates that are available for debt with similar terms.
t.              Earnings (Loss) Per Share
We have adopted the provisions of FASB’s guidance for determining whether instruments granted in share-based payment transactions are participating securities.  The guidance requires that all outstanding unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (such as restricted stock awards granted by us) be considered participating securities.  Because the restricted stock awards are participating securities, we are required to apply the two-class method of computing basic and diluted earnings per share (the “Two-Class Method”).
Basic EPS is determined using the Two-Class Method and is computed by dividing earnings attributable to Ultralife common shareholders by the weighted-average shares outstanding during the period.  The Two-Class Method is an earnings allocation formula that determines earnings per share for each class of common stock and participating security according to dividends declared and participation rights in undistributed earnings.  Diluted EPS includes the dilutive effect of securities, if any, and reflects the more dilutive EPS amount calculated using the treasury stock method or the Two-Class Method.  For the years ended December 31, 2013 and 2012, both the Two-Class Method and the treasury stock method calculations for diluted EPS yielded the same result.
The computation of basic and diluted earnings per share is summarized as follows:
		Years Ended December 31,
		2013			2012
Net Loss from continuing operations attributable to Ultralife		$	(1,054	)	$	(1,097	)
Net Loss from continuing operations attributable to participating securities (unvested restricted stock awards) (120,000 and -0- shares, respectively)			-			-
Net Loss from continuing operations attributable to Ultralife common shareholders (a)			(1,054	)		(1,097	)
Net Income (Loss) from discontinued operations attributable to Ultralife common shareholders (c)		$	128		$	(501	)
Average Common Shares Outstanding – Basic (e)			17,465,000			17,403,000
Effect of Dilutive Securities:
Stock Options / Warrants			-			-
Average Common Shares Outstanding – Diluted (f)			17,465,000			17,403,000
EPS – Basic (a/e) – continuing operations		$	(0.06	)	$	(0.06	)
EPS – Basic (c/e) – discontinued operations		$	0.01		$	(0.03	)
EPS – Diluted (b/f) – continuing operations		$	(0.06	)	$	(0.06	)
EPS – Diluted (d/f) – discontinued operations		$	0.01		$	(0.03	)
There were 2,251,622 outstanding stock options, warrants and restricted stock awards as of December 31, 2013, that were not included in EPS as the effect would have been anti-dilutive. No outstanding stock options, warrants and restricted stock awards were included in the dilution computation for the year ended December 31, 2013. There were 2,211,488 outstanding stock options, warrants and restricted stock awards as of December 31, 2012, that were not included in EPS as the effect would have been anti-dilutive. No outstanding stock options, warrants and restricted stock awards were included in the dilution computation for the year ended December 31, 2012.
u.             Stock-Based Compensation
We have various stock-based employee compensation plans, which are described more fully in Note 7.   We follow the provisions of FASB’s guidance on share-based payments, which requires that compensation cost relating to share-based payment transactions be recognized in the financial statements.  The cost is measured at the grant date, based on the fair value of the award, and is recognized as an expense over the employee’s requisite service period (generally the vesting period of the equity award).
v.             Segment Reporting
We report segment information in accordance with FASB’s guidance on Disclosures about Segments of an Enterprise and Related Information.   We have two operating segments.  The basis for determining our operating segments is the manner in which financial information is used by us in our operations.  Management operates and organizes itself according to business units that comprise unique products and services across geographic locations.
On February 15, 2012, we decided to divest our RedBlack Communications business, which previously was reported in the Communications Systems segment.  Further, in Q4 of 2012, we elected not to renew the lease for our U.K. manufacturing facility which expired on March 24, 2013. The results of the discontinued UK operations were previously reported in the Battery and Energy Products segment. See Note 2 in these Notes to Consolidated Financial Statements for additional information.
w.             Recent Accounting Pronouncements
In July 2013, the FASB issued ASU 2013-11 “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss or a Tax Credit Carryforward Exists.” With certain exceptions, ASU 2013-11 requires entities to present an unrecognized tax benefit, or portion of an unrecognized tax benefit, as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward. The guidance is effective for interim and annual periods beginning after December 15, 2013 on either a prospective or retrospective basis with early adoption permitted. We do not expect adoption of this guidance to have a material impact on its consolidated results of operations and financial condition.
In March 2013, the FASB issued ASU 2013-05, “Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity.” ASU 2013-05 provides that the cumulative translation adjustment is released into net income when a reporting entity ceases to have a controlling interest in a subsidiary that is controlled by a consolidated foreign entity. Further, this update states that the sale of an investment in a foreign entity includes both events that result in the loss of a controlling financial interest in a foreign entity, regardless of any retained investment, and events that result in an acquirer obtaining control through a step acquisition. ASU 2013-05 is effective prospectively for fiscal years beginning after December 15, 2013, with early adoption permitted. We do not believe that adoption of this standard will have a material impact on our consolidated results of operations and financial condition.
In February 2013, the FASB issued ASU 2013-04 “Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation is Fixed at the Reporting Date.” ASU 2013-04 requires an entity to measure such obligations as the sum of the amount that the reporting entity agreed to pay on the basis of its arrangement with co-obligors and any additional amount the reporting entity expects to pay on behalf of its co-obligors. The guidance is effective for interim and annual periods beginning after December 15, 2013. Retrospective presentation for all comparative periods presented is required with early adoption permitted. We do not expect adoption of this guidance to have a material impact on its consolidated results of operations and financial condition.
In February 2013, the FASB issued ASU 2013-02, “Reporting of Amounts Reclassified out of Accumulated Other Comprehensive Income.” ASU 2013-02 requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component as well as presentation, either on the face of the financial statement or in the notes, of significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional detail about those amounts. ASU 2013-02 is effective for fiscal years beginning after December 15, 2012. Adoption of this standard did not have a material impact on our consolidated results of operations and financial condition.

	Note 2- Dispositions & Exit Activities
	2012 Activity
	Ultralife Batteries UK, Ltd.
	During the fourth quarter of 2012, we elected not to renew the lease for our U.K. manufacturing facility which expired on March 24, 2013, and to relocate our sales and services operations to a smaller facility. As a result of this decision, we were required to restore the facility back to its original condition per a previous contractual commitment.
	The costs associated with the lease exit did not become determinable until late in the fourth quarter of 2012. Accordingly, we recorded a liability as of the end of 2012 for our the estimated costs to return the facility to its original condition as well as other related expenses that resulted in $228 being charged to selling, general, and administrative costs related to operations transferred to our facilities in Newark, NY, and an additional $815 being recorded as discontinued operations for those operations that were not transferred to our facilities in Newark, NY. The termination of the lease led to no employee reductions or other termination costs, with the exception of the aforementioned restoration costs. We paid these costs in full in the first quarter of 2013 and recorded a gain from discontinued operations for the difference between estimated and actual costs.
	As a result, the Consolidated Statements of Comprehensive Income (Loss) herein exclude the discontinued Ultralife Batteries UK, Ltd. operations from the results of continuing operations.  The following amounts have been reported as discontinued operations for years ended December 31, 2013 and 2012:

	RedBlack Communications, Inc.
	On February 16, 2012, we announced our intention to divest our RedBlack Communications, Inc. (“RedBlack”) business in 2012. RedBlack was a wholly owned subsidiary of ours based in Hollywood, Maryland, that designed, integrated and fielded mobile, modular and fixed site communication and electronic systems.  We determined that RedBlack offered limited opportunities to achieve the operating thresholds of our new business model.
	On September 28, 2012, we entered into and closed a Stock Purchase Agreement (the “Agreement”) to sell 100% of our capital stock in RedBlack to BCF Solutions, Inc.  In exchange for the sale of RedBlack, we received $2,533 as a purchase price, comprised of cash at closing in the amount of $2,133, funds held in escrow for up to one year in the amount of $250, as well as $150 to be available for RedBlack employee retention programs.  Amounts charged to expense of $125 are due to customary post-closing working capital adjustments that have been recognized over the course of 2013.
	The Agreement contains customary representations and warranties that will survive for a period of two or three years.  The Agreement also contains customary indemnification for breaches of the representations and warranties identified in the Agreement.
	Pursuant to the Agreement, we are prohibited from engaging or participating with any current customer of RedBlack in any business, directly or indirectly, that competes with the business conducted by RedBlack for two years.  We are also prohibited from hiring, soliciting, or recruiting any current employee, independent contractor, or consultant of BCF Solutions, Inc. or RedBlack for two years.
	Commencing with the first quarter of 2012, the results of the RedBlack operations and related divestiture costs have been reported as a discontinued operation.
	As a result, the Consolidated Statements of Operations and Comprehensive Income (Loss) herein exclude the RedBlack operations from the results of continuing operations.  The following amounts have been reported as discontinued operations for years ended December 31, 2013 and 2012:
		Years Ended December 31,
		2013			2012
	Net sales	$	-		$	3,404
	Loss from discontinued operations		(125	)		(7	)
	(Provision) benefit for income taxes		-			174
	Income (Loss) from discontinued operations, net of tax	$	(125	)	$	167
	Prior Activity
	As it relates to our operations closed prior to 2012, we reported income of $12 and $147 for the years ended December 31, 2013 and 2012, respectively. Income in both years is due entirely to adjustments to reserves that were established as of the closure of the business as our actual experience has differed from our expectations at that time.

	Depreciation expense was $2,957 and $3,306 for the years ended December 31, 2013 and 2012, respectively.
	c.             Impairment of Goodwill, Intangible Assets and Long-Lived Assets
	We applied the provisions of FASB ASC Topics 350-20 and 820 during the annual goodwill impairment analysis performed in October 2013. The first, optional, step of the goodwill analysis is to determine if it is more likely than not that the fair value of the identified reporting units exceeds the respective carrying value. This qualitative analysis includes but is not limited to, an evaluation of the macroeconomic, industry or market, and cost factors relevant to the reporting unit as well as financial performance and entity or reporting unit events that may affect the value of the reporting unit.  We elected to forego the qualitative assessment on all three of the identified reporting units. If the conclusion that it is more likely than not that the fair value of the reporting unit exceeds its carrying value cannot be supported, or if the reporting unit is not subjected to the qualitative assessment, the fair value of the reporting unit is determined using a quantitative assessment. The fair value for our reporting units subjected to this quantitative test could not be determined using readily available quoted Level 1 inputs or Level 2 inputs that were observable in active markets.  Therefore, we used an income approach, to estimate the fair value of the reporting units, using Level 3 inputs.  To estimate the fair value of the reporting unit, we used significant estimates and judgmental factors.  The key estimates and factors used in the valuation model included revenue growth rates and profit margins based on internal forecasts, as well as industry and market based terminal growth rates, inputs to the weighted-average cost of capital used to discount future cash flows, and earnings multiples.  As a result of the goodwill impairment tests performed during 2013 and 2012, no impairment was indicated.
	Similar to goodwill, we applied the provisions of FASB Topics 350-30 and 820, during the annual indefinite-lived intangible asset analysis performed in September and October 2013. The first, optional, step of the analysis is to determine if it is more likely than not that the fair value of the indentified indefinite-lived intangible assets exceeds the respective carrying values. This qualitative analysis includes but is not limited to, an evaluation of the macroeconomic, industry or market, and other factors relevant to the indefinite-lived intangible asset.  We elected to forego the qualitative assessment on all four identified indefinite-lived intangible assets. If a conclusion that it is more likely than not that the fair value of the indefinite-lived intangible asset cannot be supported or if this optional step is not applied to the indefinite-lived intangible asset, the fair value of the indefinite-lived intangible asset is determined using a quantitative assessment. The fair value for our indefinite-lived intangible assets subjected to this quantitative test could not be determined using readily available quoted Level 1 inputs or Level 2 inputs that were observable in active markets.  Therefore, we used a royalty relief approach, to estimate the fair value of the indefinite-lived intangible assets, using Level 3 inputs.  To estimate the fair value of the indefinite-lived intangible asset, we used significant estimates and judgmental factors.  The key estimates and factors used in the valuation model included revenue growth rates, as well as industry and market based terminal growth rates, inputs to the weighted-average cost of capital used to discount future cash flows, and determined royalty rates.  As a result of the impairment tests performed during 2013 and 2012, no impairment was indicated.
	During 2013 and 2012, we also evaluated certain fixed assets for impairment utilizing valuation methods that are classified as Level 3 inputs. Based upon the results of this evaluation, no material impairment was indicated.

	Credit Facilities
	On May 24, 2013, we entered into a Revolving Credit, Guaranty and Security Agreement (the “Credit Agreement”) and related security agreements with PNC Bank, National Association (“PNC”) to establish a $20 million secured asset-based revolving credit facility that includes a $1 million letter of credit subfacility (the “Credit Facility”).  The Credit Agreement provides that the Credit Facility may be increased with the PNC’s concurrence to $35 million prior to the last six months of the term and expires on May 24, 2017.  The Credit Facility replaces the prior credit facility with RBS Business Capital, a division of RBS Asset Finance, Inc., which expired in accordance with its terms on May 15, 2013, with no debt outstanding.
	Our available borrowing limit under the Credit Facility fluctuates from time to time based on a borrowing base formula equal to the sum of up to 85% of eligible accounts receivable plus the least of (a) up to 65% of the eligible inventory and eligible foreign in-transit inventory, (b) up to 85% of the appraised net orderly liquidation value of eligible inventory and eligible foreign in-transit inventory, and (c) $7.5 million, in each case subject to the definitions in the Credit Agreement and reserves required by PNC.
	Interest is payable quarterly and will accrue on outstanding indebtedness under the Credit Agreement at the alternate base rate, as defined in the Credit Agreement, plus the applicable margin or at the one, two or three month LIBOR rate plus the applicable margin as selected by us from time to time and listed below.
	Quarterly Average Undrawn	Applicable Margin for			Applicable Margin for
	Borrowing Availability	Alternate Base Rate Loans			LIBOR Rate Loans
	Greater than $8,000,000		1	%		2	%
	$5,000,000 up to $8,000,000		1.25	%		2.25	%
	Less than $5,000,000		1.5	%		2.5	%
	We must pay a fee on the Credit Facility’s unused availability of 0.375% per annum and customary letter of credit fees in addition to various collateral monitoring and related fees and expenses.
	In addition to customary affirmative and negative covenants, we must maintain a fixed charge coverage ratio as defined in the Credit Agreement of 1:15 to 1:00 tested quarterly for the four-quarters then ended.  As of December 31, 2013 we were in compliance with all covenants. The Credit Facility is secured by substantially all our assets.
	Any outstanding advances must be repaid upon expiration of the term of the Credit Facility.  Payments must be made during the term to the extent outstanding advances exceed the maximum amount then permitted to be drawn as advances under the Credit Facility and from the proceeds of certain transactions.  Upon the occurrence of an event of default, the outstanding obligations may be accelerated and PNC will have other customary remedies.
	As of December 31, 2013, we had $-0- outstanding under the Credit Facility, an applicable interest rate of 2.17%, approximately $12,969 of borrowing capacity in addition to our unrestricted cash on hand of $16,066, and no outstanding letters of credit related to the Credit Facility.

	As of December 31, 2013, we have made commitments to purchase approximately $221 of production machinery and equipment.
	c.              Royalty Agreements
	Technology underlying certain of our products is based in part on non-exclusive transfer agreements.  In 2003, we entered into an agreement with Saft Groupe S.A., to license certain tooling for battery cases.  The licensing fee associated with this agreement is based on a percentage of the sales price of the individual battery case, up to a maximum of one dollar per battery case.  The total royalty expense reflected in 2013 and 2012 was $1 in each year.  This agreement expires in the year 2017.
	d.             Government Grants/Loans
	In conjunction with the City of West Point, Mississippi, we applied for a Community Development Block Grant (“CDBG”) from the State of Mississippi for infrastructure improvements to our leased facility that is owned by the City of West Point, Mississippi.  The CDBG was awarded and as of December 31, 2011, approximately $480 has been distributed under the grant.  Under an agreement with the City of West Point, we agreed to employ at least 30 full-time employees at the facility, of which 51% of the jobs had to be filled or made available to low or moderate income families, within three years of completion of the CDBG improvement activities.  In addition, we agreed to invest at least $1,000 in equipment and working capital into the facility within the first three years of operation of the facility.  While we have yet to receive formal notice from the applicable government agency confirming the closure of the grant, we believe that both of these commitments were satisfied as of March 2011 and, therefore, have not recorded an accrual with respect to any potential liability for the grant amounts received under the CDBG.
	In conjunction with Clay County, Mississippi, we applied for a Mississippi Rural Impact Fund Grant (“RIFG”) from the State of Mississippi for infrastructure improvements to our leased facility that is owned by the City of West Point, Mississippi.  The RIFG was awarded and as of December 31, 2011, approximately $150 has been distributed under the grant.  Under an agreement with Clay County, we agreed to employ at least 30 full-time employees at the facility, of which 51% of the jobs had to be filled or made available to low or moderate income families, within two years of completion of the RIFG improvement activities.  In September 2010, we received an extension for this commitment to March 31, 2011.  In addition, we agreed to invest at least $1,000 in equipment and working capital into the facility within the first three years of operation of the facility.  While we have yet to receive formal notice from the applicable government agency confirming the closure of the grant, we believe that both of these commitments were satisfied as of March 2011 and, therefore, have not recorded an accrual with respect to any potential liability for the grant amounts received under the RIFG.
	e.             China
	Our operating facility in China presents risks including, but not limited to, changes in local regulatory requirements, including changes in labor laws, local wage laws, environmental regulations, taxes and operating licenses, compliance with U.S. regulatory requirements, including the Foreign Corrupt Practices Act, uncertainties as to application and interpretation of local laws and enforcement of contract and intellectual property rights, eminent domain claims, labor disputes, rapid changes in government, economic and political policies, and other various contingencies that are outside of our control.  Any such event could depress our earnings and have other material adverse effects on our business, financial condition and results of operations.
	f.              Employment Contracts
	We have an employment contract with Michael D. Popielec, our President and Chief Executive Officer, which stays in effect until terminated by either party.  This agreement provides for a base salary, as adjusted for increases at the discretion of our Board of Directors, and includes incentive bonuses based upon attainment of specified quantitative and qualitative performance goals.  This agreement also provides for severance payments in the event of specified events of termination of employment.  In addition, this agreement provides for a lump sum payment in the event of termination of employment in connection with a change in control.
	As part of our employment commencement process, employees are required to enter into agreements providing for confidentiality of certain information and the assignment of rights to inventions made by them while employed by us. These agreements also contain certain noncompetition and nonsolicitation provisions effective during the employment term and for varying periods thereafter depending on position and location. There can be no assurance that we will be able to enforce these agreements.  All of our employees agree to abide by the terms of a Code of Ethics policy that provides for the confidentiality of certain information received during the course of their employment.
	g.             Product Warranties
	We estimate future costs associated with expected product failure rates, material usage and service costs in the development of our warranty obligations.  Warranty reserves are based on historical experience of warranty claims and generally will be estimated as a percentage of sales over the warranty period.  In the event the actual results of these items differ from the estimates, an adjustment to the warranty obligation would be recorded.  Changes in our product warranty liability during the years ended December 31, 2013 and 2012 were as follows:
		2013			2012
	Balance at beginning of year	$	607		$	839
	Accruals for warranties issued		20			370
	Settlements made		(114	)		(602	)
	Balance at end of year	$	513		$	607
	h.             Post Audits of Government Contracts
	We had certain “exigent”, non-bid contracts with the U.S. government, which were subject to audit and final price adjustment, which resulted in decreased margins compared with the original terms of the contracts.  As of December 31, 2012, there were no outstanding exigent contracts with the U.S. government.  As part of its due diligence, the U.S. government has conducted post-audits of the completed exigent contracts to ensure that information used in supporting the pricing of exigent contracts did not differ materially from actual results.  In September 2005, the Defense Contracting Audit Agency (“DCAA”) presented its findings related to the audits of three of the exigent contracts, suggesting a potential pricing adjustment of approximately $1,400 related to reductions in the cost of materials that occurred prior to the final negotiation of these contracts.  In addition, in June 2007, we received a request from the Office of Inspector General of the Department of Defense (“DoD IG”) seeking certain information and documents relating to our business with the Department of Defense.  We cooperated with the DCAA audit and DoD IG inquiry by making available to government auditors and investigators our personnel and furnishing the requested information and documents.  The DCAA Audit and DoD IG inquiry were consolidated and the US Attorney’s Office represented the government in connection with these matters.  Under applicable federal law, we may have been subject up to treble damages and penalties associated with the potential pricing adjustment.  In light of the uncertainty, we decided to enter into discussions with the U.S. Attorney’s Office in April 2011 to negotiate a settlement that would be in the best interests of our customers, employees and shareholders.  On April 21, 2011, we were advised by the government that there was a $2,730 settlement-in-principle to resolve all claims related to the contracts, subject to final approval by the Department of Justice.  As a result, we recorded a $2,730 charge as a reduction in revenues for the first quarter of 2011.  On June 1, 2011, we entered into a Settlement Agreement with the United States of America, acting through the United States Department of Justice and on behalf of the Department of Defense that required us to pay a total of $2,700 plus accrued interest thereon at the rate of 2.625% per annum. Under the Settlement Agreement, we were required to make principal payments of $1,000, $567, $567 and $566 being due on June 8, 2011, December 1, 2011, June 1, 2012 and December 1, 2012, respectively.  Each principal payment was accompanied by a payment of accrued interest.  As of December 31, 2012, we had made all required payments.
	i.             Legal Matters
	We are subject to legal proceedings and claims that arise in the normal course of business.   We believe that the final disposition of such matters will not have a material adverse effect on our financial position, results of operations or cash flows.
	Arista Power Litigation
	On September 23, 2011, we initiated an action against Arista Power, Inc. (“Arista”) and our former senior sales and engineering employee, David Modeen (“Modeen”) in the State of New York Supreme Court, County of Wayne (Index No. 73379).  In our Complaint, we allege that Arista recruited all but one of the members of its executive team from us, subsequently changed and redirected its business to compete directly with us by using our confidential information, and during the summer of 2011, recruited Modeen to become an Arista employee.  We allege that, as a result of actions by Arista and Modeen: (i) Modeen has breached the terms of his Employee Confidentiality, Non-Disclosure, Non-Compete, Non-Disparagement and Assignment Agreement with us; (ii) Modeen has breached certain agreements, duties and obligations he owed us, including to protect and refrain from disclosing our trade secrets and confidential and proprietary information; (iii) Arista’s employment of Modeen will inevitably lead to the disclosure and use of our trade secrets by Arista, in violation of Modeen’s duties and obligations to us; (iv) Arista unlawfully induced Modeen to breach his agreements with and duties and obligations to us; and (v) Arista’s recruitment and employment of Modeen has breached a subcontract between Arista and us.  We seek damages as determined at trial and preliminary and permanent injunctive relief.  The defendants have answered the allegations set forth in the Complaint, without asserting any counterclaims.
	On December 5, 2011, Arista served us with a Complaint it filed on November 29, 2011 in the State of New York Supreme Court, County of Monroe (Index No.  11-13896) against us, our officers, several of our directors, and an employee.  In its Complaint, Arista alleges that we and our named defendants have violated the terms of a Confidentiality Agreement with Arista and have unfairly competed against Arista by unlawfully appropriating Arista’s trade secrets and that as a result of such activity, Arista has incurred damages in excess of $60,000.  Arista seeks damages, an accounting, and preliminary and permanent injunctive relief.
	On December 21, 2011, we and our officers, directors and employee named in Arista’s Complaint filed a motion to dismiss Arista’s Complaint against our officers, directors and employee as Arista’s Complaint fails to state any cause of action against any of them and to dismiss the claim of fraud against our officers, directors and employee.  Subsequently, Arista filed an Amended Complaint alleging essentially the same causes of action but adding additional factual allegations against us and our officers, directors and employee.  In addition, Arista filed a motion to disqualify our outside legal counsel representing us and our officers, directors and employee in both Arista’s Complaint and our Complaint against Arista.  In response, we and our officers, directors and employee filed a new motion to dismiss Arista’s Complaint against us in its entirety and seeking dismissal of the fraud claim against us.  Arista’s motion to disqualify our outside legal counsel was denied on February 10, 2012.  On March 9, 2012, the Court issued its decision on our motion to dismiss, granting the motion to the extent of dismissing some claims against us, but denying the motion to dismiss the individuals from the lawsuit at this preliminary stage.  On April 19, 2012, an Answer was filed on behalf of us, our officers, directors and employee. On September 10, 2013, Arista filed a Second Amended Complaint deleting all individual defendants except our named employee, to which an Answer was filed on our behalf on September 30, 2013. Discovery has commenced with respect to the Arista litigation and is ongoing.
	We initiated the September 23, 2011 Complaint against Arista Power to protect our customers, employees and shareholders from the unauthorized use and theft of our investments in intellectual property, trade secrets and confidential information by Arista and its employees.  Protecting our collective intellectual property and know-how, developed at great cost to us to form our competitive position in the marketplace and create value for our shareholders, is a fundamental responsibility of all our employees.
	We believe the November 29, 2011 Arista Complaint is retaliatory and without merit.  Our development of the foundation for the new product concept for which Arista claims we allegedly used its trade secrets commenced in 2008, long prior to the departure of those individuals who now constitute the executive team of Arista.  Furthermore, we believe the purported damage of $60,000 being claimed by Arista is based solely on the reduction in its market capitalization between November 2009 and the filing date of the Complaint. This market value loss is totally unrelated to any actions on account of us, and claims for recovery of this or any other amount are legally and factually baseless.
	Accordingly, we will vigorously pursue our complaint against Arista and defend what we believe to be a meritless action on the part of Arista Power.
	9-Volt Battery Litigation
	In July 2010, we were served with a summons and complaint filed in Japan by one of our 9-volt battery customers. The complaint alleged damages associated with claims of breach of warranty in an amount of approximately $1,100. A trial was held on May 25, 2012, in Japan before a panel of three judges, after which the parties agreed to settle the matter for approximately $125, which has been reflected in our cost of products sold in 2012.  The terms of the settlement agreement include no legal liability on our part and the plaintiff abandoning all other claims against us.

Stockholders' Equity Note [Abstract]	'
Stockholders' Equity Note Disclosure [Text Block]	'
	Note 7 - Shareholders' Equity
	a.             Preferred Stock
	We have authorized 1,000,000 shares of preferred stock, with a par value of $0.10 per share.  At December 31, 2013, no preferred shares were issued or outstanding.
	b.             Common Stock
	We have authorized 40,000,000 shares of common stock, with a par value of $0.10 per share.
	In August 2013, we issued 15,272 shares of common stock to our non-employee directors, valued at $57.  In November 2013, we issued 4,573 shares of our common stock to our non-employee directors, valued at $16.
	In February 2012, we issued 16,271 shares of our common stock to our non-employee directors, valued at $77.  In May 2012, we issued 17,473 shares of our common stock to our non-employee directors, valued at $77.  In August 2012, we issued 24,311 shares of our common stock to our non-employee directors, valued at $77.  In November 2012, we issued 25,758 shares of our common stock to our non-employee directors, valued at $77.
	c.             Treasury Stock
	At December 31, 2013 and 2012, we had 1,372,757 shares of treasury stock outstanding, valued at $7,658.
	d.             Stock Options
	We have various stock-based employee compensation plans, for which we follow the provisions of FASB’s guidance on share-based payments, which requires that compensation cost relating to share-based payment transactions be recognized in the financial statements.  The cost is measured at the grant date, based on the fair value of the award, and is recognized as an expense over the employee’s requisite service period (generally the vesting period of the equity award).
	Our shareholders have approved various equity-based plans that permit the grant of stock options, restricted stock and other equity-based awards. In addition, our shareholders have approved the grant of stock options outside of these plans.
	In June 2004, shareholders adopted the 2004 Long-Term Incentive Plan (“LTIP”) pursuant to which we were authorized to issue up to 750,000 shares of common stock and grant stock options, restricted stock awards, stock appreciation rights and other stock-based awards.  Through shareholder approved amendments to the LTIP in 2006, 2008, 2011, and 2013, the total number of authorized under the LTIP increased to 2,900,000.
	Stock options granted under the LTIP are either Incentive Stock Options (“ISOs”) or Non-Qualified Stock Options (“NQSOs”).  Key employees are eligible to receive ISOs and NQSOs; however, directors and consultants are eligible to receive only NQSOs. Most ISOs vest over a three- or five-year period and expire on the sixth or seventh anniversary of the grant date.  All NQSOs issued to non-employee directors vest immediately and expire on either the sixth or seventh anniversary of the grant date.  Some NQSOs issued to non-employees vest immediately and expire within three years; others have the same vesting characteristics as options given to employees. As of December 31, 2013, there were 2,035,688 stock options outstanding under the LTIP.
	On December 19, 2005, we granted our former President and Chief Executive Officer, John, D. Kavazanjian, an option to purchase 48,000 shares of common stock at $12.96 per share outside of any of our equity-based compensation plans, subject to shareholder approval.  Shareholder approval was obtained on June 8, 2006.  The stock option was fully vested and expired on June 8, 2013.
	On March 7, 2008, in connection with his becoming employed by us, we granted our Chief Financial Officer and Treasurer, Philip A. Fain, an option to purchase 50,000 shares of common stock at $12.74 per share outside of any of our equity-based compensation plans.  The option is fully vested and expires on March 7, 2015.
	On December 30, 2010, pursuant to the terms of his employment agreement, we granted our President and Chief Executive Officer, Michael D. Popielec, options to purchase shares of common stock under the LTIP as follows: (i) 50,000 shares at $6.42, vesting in annual increments of 12,500 shares over a four-year period commencing December 30, 2011; (ii) 250,000 shares at $6.42, vesting in annual increments of 62,500 shares over a four-year period commencing December 30, 2011; (iii) 200,000 shares at $10.00, with vesting to begin on the date the stock reaches a closing price of $10.00 per share for 15 trading days within a 30-day trading period, with such vesting in annual increments of 50,000 shares over the four anniversary dates of that date; and (iv) 200,000 shares at $15.00, with vesting to begin on the date the stock reaches a closing price of $15.00 per share for 15 trading days within a 30-day trading period, with such vesting in annual increments of 50,000 shares over the four anniversary dates of that date.  All such options in items (i) and (ii) shall expire on December 30, 2017.  All such options in items (iii) and (iv) shall expire as of the later of December 30, 2017 and five years after the initial vesting commences, but in no event later than December 30, 2020.  The options set forth in items (ii), (iii) and (iv) were subject to shareholder approval of an amendment to the LTIP, which approval was obtained on June 7, 2011.
	On January 3, 2011, pursuant to the terms of his employment agreement, we granted our President and Chief Executive Officer, Michael D. Popielec, an option to purchase 50,000 shares of common stock at $6.58 under the LTIP.  The option vests in annual increments of 12,500 shares over a four-year period commencing December 30, 2011.  The option expires on December 30, 2017.
	In conjunction with FASB’s guidance for share-based payments, we recorded compensation cost related to stock options of $774 and $1,073 for the years ended December 31, 2013 and 2012, respectively.  As of December 31, 2013, there was $669 of total unrecognized compensation costs related to outstanding stock options, which is expected to be recognized over a weighted average period of 1.41 years.
	We use the Black-Scholes option-pricing model to estimate fair value of stock-based awards.  The following weighted average assumptions were used to value options granted during the years ended December 31, 2013 and 2012:
				Years Ended
				December 31,
				2013				2012
	Risk-free interest rate			0.78	%			0.56	%
	Volatility factor			61.94	%			63.53	%
	Dividends			0	%			0	%
	Weighted average expected life (years)			4.06				3.91
	Forfeiture rate			12.33	%			15	%
	We use a Monte Carlo simulation option-pricing model to estimate the fair value of market performance stock-based awards, of which there were no new awards in the years ended December 31, 2013 or 2012.
	We calculate expected volatility for stock options by taking an average of historical volatility over the past five years and a computation of implied volatility.  The computation of expected term was determined based on historical experience of similar awards, giving consideration to the contractual terms of the stock-based awards and vesting schedules.  The interest rate for periods within the contractual life of the award is based on the U.S. Treasury yield in effect at the time of grant.  Forfeiture rates are calculated by dividing unvested shares forfeited by beginning shares outstanding.  The pre-vesting forfeiture rate is calculated yearly and is determined using a historical twelve-quarter rolling average of the forfeiture rates.
	The following tables summarize data for the stock options issued by us:

The weighted average fair value of options granted during the years ended December 31, 2013 and 2012 was $1.70 and $1.67, respectively.  The total intrinsic value of options (which is the amount by which the stock price exceeded the exercise price of the options on the date of exercise) exercised during the years ended December 31, 2013 and 2012 was $1 and $29, respectively.
FASB’s guidance for share-based payments requires cash flows from excess tax benefits to be classified as a part of cash flows from financing activities.  Excess tax benefits are realized tax benefits from tax deductions for exercised options in excess of the deferred tax asset attributable to stock compensation costs for such options.  We did not record any excess tax benefits in 2013 or 2012.  Cash received from option exercises under our stock-based compensation plans for the years ended December 31, 2013 and 2012 was $12 and $114, respectively.
e.             Restricted Stock Awards
On January 29, 2013, we granted 120,000 contingent restricted stock units to our President and Chief Executive Officer, Michael D. Popielec, subject to shareholder approval, which was obtained on June 4, 2013, which vest as follows: (i) 30,000 shares of our common stock will vest on the later of January 1, 2014 or the date when our common stock first reaches a closing price of $4.00 per share for 15 trading days in a 30 trading day period; (ii) 30,000 shares of our common stock will vest on the later of January 1, 2014 or the date when our common stock first reaches a closing price of $5.00 per share for 15 trading days in a 30 trading day period; (iii) 30,000 shares of our common stock will vest on the later of January 1, 2015 or the date when our common stock first reaches a closing price of $4.00 per share for 15 trading days in a 30 trading day period; and (iv) 30,000 shares of our common stock will vest on the later of January 1, 2015 or the date when our common stock first reaches a closing price of $5.00 per share for 15 trading days in a 30 trading day period.
The restricted stock units described in (i) and (iii) had achieved their closing price condition prior to shareholder approval and were valued at the closing price on the date of grant. The restricted stock units described in (ii) and (iv) had not yet achieved their closing price conditions and were valued utilizing a Monte Carlo simulation to determine fair value and the derived service period. The weighted average inputs utilized were:
		Year Ended

We recorded compensation cost related to restricted stock grants of $284 and $8 for the years ended December 31, 2013 and 2012, respectively.  As of December 31, 2013, we had $150 of total unrecognized compensation expense related to restricted stock grants. The total fair value of these grants that vested during the years ended December 31, 2013 and 2012 was $0 and $5, respectively.
f.             Reserved Shares
We have reserved 2,860,723 and 2,911,723 shares of common stock under the various stock option plans, warrants and restricted stock awards as of December 31, 2013 and 2012, respectively.

	We reflected a tax expense of $239 for the year ended December 31, 2013. The 2013 tax provision is principally a result of the increase in the net deferred tax liability related to deferred tax liabilities generated from goodwill and certain intangible assets that cannot be predicted to reverse for book purposes during our loss carryforward periods.  In addition, we incurred foreign income taxes in 2013.
	We reflected a tax expense of $380 for the year ended December 31, 2012. The 2012 tax provision is principally a result of the increase in the net deferred tax liability related to liabilities generated from goodwill and certain intangible assets that cannot be predicted to reverse for book purposes during our loss carryforward periods.  In addition, we incurred foreign income taxes in 2012.
	Deferred income taxes reflect the net tax effect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amount used for income tax purposes.  Significant components of our deferred tax liabilities and assets are as follows:
		Years Ended December 31,

	Net deferred tax liability	$	(4,160	)	$	(4,040	)
	The $4,160 net deferred tax liability for the year ended December 31, 2013 is comprised of a current deferred tax liability of $9 and a long-term deferred tax liability of $4,242, offset partially by current deferred tax asset of $91. The $4,040 net deferred tax liability for the year ended December 31, 2012 is comprised of a long-term deferred tax liability of $4,160, offset partially by current deferred tax asset of $120.
	In 2013 and 2012, in the U.S. and the U.K., we continue to report a valuation allowance for our deferred tax assets that cannot be offset by reversing temporary differences.  This results from the conclusion that it is more likely than not that we would not utilize our U.S. and U.K. NOL’s that had accumulated over time.  The recognition of a valuation allowance on our deferred tax assets resulted from our evaluation of all available evidence, both positive and negative.  The assessment of the realizability of the NOL’s was based on a number of factors including, our history of net operating losses, the volatility of our earnings, our historical operating volatility, our historical inability to accurately forecast earnings for future periods and the continued uncertainty of the general business climate as of the end of 2013.   We concluded that these factors represent sufficient negative evidence and have concluded that we should record a full valuation allowance under FASB‘s guidance on the accounting for income taxes.  In  2013 and 2012, we did not record a valuation allowance for the Chinese deferred tax assets as we determined that it was more likely than not that they would be realized.   We continually assess the carrying value of this asset based on relevant accounting standards.
	As of December 31, 2013, we have foreign and domestic NOL’s totaling approximately $62,152 available to reduce future taxable income. Foreign loss carryforwards of approximately $12,390 can be carried forward indefinitely. The domestic NOL carryforward of $49,762 expires from 2019 through 2033.  The domestic NOL carryforward includes approximately $2,949 for which a benefit will be recorded in capital in excess of par value when realized.
	For financial reporting purposes, income (loss) from continuing operations before income taxes is as follows:
		Years Ended December 31,
		2013			2012
	United States	$	(875	)	$	829
	Foreign		26			(1,403	)
	Total	$	(849	)	$	(574	)
	There are no undistributed earnings of our foreign subsidiaries, at December 31, 2013 or 2012.
	As of December 31, 2011, the tax holiday for our Chinese operations expired and the full corporate rate of 25% became effective. In 2013, our tax rate in China was reduced to 15% due to the successful application for certain tax designations.
	The provision for income taxes differs from the amount of income tax determined by applying the applicable U.S. statutory federal income tax rate to income (loss) from continuing operations before income taxes as follows:
		Years Ended December 31,
		2013			2012
	Provision/(benefit) computed using the statutory rate		(34.0	%)		(34.0	%)
	Increase (reduction) in taxes resulting from:
	Foreign		1.2			127.6
	Valuation allowance		20.3			(119.3	)
	Equity compensation		38.6			55.4
	Expiration of capital loss carryforward		-			59.6
	Other		2.1			7.2
	Provision (benefit) for income taxes		28.2	%		96.5	%
In 2013 and 2012, the provision for income taxes was higher than what would be expected if the statutory rate were applied to pretax income.  This is due to the continuation of reflecting a full valuation allowance for our U.S. and U.K. deferred tax assets, certain non-deductible expenses for tax purposes, and foreign earnings.
Accounting for Uncertainty in Income Taxes
Our unrecognized tax benefits related to uncertain tax positions at December 31, 2013 relate to Federal and various state jurisdictions.  The following table summarizes the activity related to our unrecognized tax benefits:
	Years ended December 31,
	2013			2012
Balance at beginning of the year	$	7,508		$	6,779
Increases related to the current year tax positions		-			729
Increases related to prior year tax positions		-			-
Decreases related to prior year tax positions		(212	)		-
Expiration of statute of limitations for assessment of taxes		-			-
Settlements		-			-
Balance at the end of the year		-			-
	$	7,296		$	7,508
The total unrecognized tax benefit balances at December 31, 2013 and 2012 are comprised of tax benefits that, if recognized, would result in a deferred tax asset and a corresponding increase in our valuation allowance.  As a result, because the benefit would be offset by an increase in the valuation allowance, there would be no effect on our effective tax rate.
We are not required to accrue interest and penalties as the unrecognized tax benefits have been recorded as a decrease in our NOL.  Interest and penalties would begin to accrue in the period in which the NOL’s related to the uncertain tax positions are utilized.  We do not expect our unrecognized tax benefits to change significantly over the next twelve months.
As a result of our operations, we file income tax returns in various jurisdictions including U.S. federal, U.S. state and foreign jurisdictions.  We are routinely subject to examination by taxing authorities in these various jurisdictions.  Our U.S. tax matters for the years 2001 through 2013 remain subject to examination by the Internal Revenue Service (“IRS”) due to our NOL carryforwards.   Our U.S. tax matters for the years 2001 through 2013 remain subject to examination by various state and local tax jurisdictions due to our NOL carryforwards.  Our tax matters for the years 2007 through 2013 remain subject to examination by the respective foreign tax jurisdiction authorities.  The IRS has completed the examination of our 2009 US Federal income tax return, with no resulting material effect to our financial position or results of operations. The IRS has informed us that the 2011 US Federal income tax year will be examined commencing in early 2014

Segment Reporting Disclosure [Text Block]	'
	Note 10 - Business Segment Information
	On February 15, 2012, we decided to divest our RedBlack Communications business, which previously was reported in the Communications Systems segment.  These results have been classified as discontinued since the first quarter of 2012. See Note 2 in these Notes to Consolidated Financial Statements for additional information.
	During the fourth quarter of 2012, we elected not to renew the lease for our U.K. manufacturing facility which expired on March 24, 2013, and to relocate our sales and services operations to a smaller facility.   As a result of this decision, we are required to restore the facility back to its original condition per a previous contractual commitment. This facility previously served our Battery and Energy Segments business. A portion of these costs were classified as a discontinued operation in the fourth quarter of 2012. See Note 2 in these Notes to Consolidated Financial Statements for additional information.
	Segment information previously reported has been reclassified to conform to the current year presentation.
	We report our results in two operating segments: Battery & Energy Products and Communications Systems.  The Battery & Energy Products segment includes: lithium 9-volt, cylindrical and various other non-rechargeable batteries, in addition to rechargeable batteries, uninterruptable power supplies, charging systems and accessories.  The Communications Systems segment includes: RF amplifiers, power supplies, cable and connector assemblies, amplified speakers, equipment mounts, case equipment, integrated communication system kits and communications and electronics systems design.  We believe that reporting performance at the gross profit level is the best indicator of segment performance.  As such we report segment performance at the gross profit level and operating expenses as Corporate charges.

Business Insurance Recoveries [Text Block]	'
	Note 11 - Fire at Manufacturing Facility
	In June 2011, we experienced a fire that damaged certain inventory and  machinery and equipment at our facility in China.  The fire occurred after business hours and was fully extinguished quickly with no injuries, and the plant was back in full operation shortly thereafter with no significant disruption in supply or service to customers.  We maintain adequate insurance coverage for this operation.
	The total amount of the loss pertaining to assets and the related expenses was approximately $1,589.  The majority of our insurance claim is related to the recovery of damaged inventory.  Through payments received in June 2012 and April 2013, we have received approximately $1,286 as a partial payment on our insurance claim, which resulted in no gain or loss being recognized.  As of December 31, 2013, we reflect a receivable from the insurance company relating to this claim of $185, which is net of our deductible of approximately $132, and represents additional proceeds to be received.  The deductible charge was expensed in the second quarter of 2011 and reflected as a component of cost of products sold in the Consolidated Statements of Operations and Comprehensive Income (Loss).

We, have not received formal notice from the village regarding these changes. However, we are evaluating our options regarding relocation and possible impacts upon our manufacturing operations. We do not have an estimate at this time regarding any costs to move or possible impact to our production, if any.

Consolidation, Policy [Policy Text Block]	'
	Principles of Consolidation
	The consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States and include the accounts of Ultralife Corporation, our wholly-owned subsidiaries, Ultralife Batteries (UK) Ltd. (“Ultralife UK”), ABLE New Energy Co., Limited, and its wholly-owned subsidiary ABLE New Energy Co., Ltd. (“ABLE” collectively), and our majority-owned subsidiary Ultralife Batteries India Private Limited (“India JV”).  Intercompany accounts and transactions have been eliminated in consolidation.
	Operations of RedBlack Communications, Inc. (“RedBlack”), our divested company and certain components of UK operations are reported as discontinued operations.
Use of Estimates, Policy [Policy Text Block]	'
	Management's Use of Judgment and Estimates
	The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at year end and the reported amounts of revenues and expenses during the reporting period.   Key areas affected by estimates include: (a) reserves for deferred tax assets, excess and obsolete inventory, warranties, and bad debts; (b) profitability on development contracts; (c) various expense accruals; (d) stock-based compensation; and, (e) carrying value of goodwill and intangible assets.  Our actual results could differ from these estimates.
Reclassification, Policy [Policy Text Block]	'
	Reclassifications
	Certain items previously reported in specific financial statement captions have been reclassified to conform to the current presentation.
Cash and Cash Equivalents, Policy [Policy Text Block]	'
	Cash and Cash Equivalents
	For purposes of the Consolidated Statements of Cash Flows, we consider all demand deposits with financial institutions and financial instruments with original maturities of three months or less to be cash equivalents.  For purposes of the Consolidated Balance Sheet, the carrying value approximates fair value because of the short maturity of these instruments.
	Our cash balances may at times exceed federally insured limits.  We have not experienced any losses in these accounts and believe we are not exposed to any significant risk with respect to cash and cash equivalents.
Receivables, Policy [Policy Text Block]	'
	Accounts Receivable and Allowance for Doubtful Accounts
	We extend credit to our customers in the normal course of business. We perform ongoing credit evaluations and generally do not require collateral.  Trade accounts receivable are recorded at their invoiced amounts, net of allowance for doubtful accounts.  We evaluate the adequacy of our allowance for doubtful accounts quarterly.  Accounts outstanding longer than contractual payment terms are considered past due and are reviewed individually for collectability.  We maintain reserves for potential credit losses based upon our loss history and specific receivables aging analysis. Receivable balances are written off when collection is deemed unlikely.
	Changes in our allowance for doubtful accounts during the years ended December 31, 2013 and 2012 were as follows:
			2013			2012
	Balance at beginning of year		$	322		$	683
	Amounts charged to expense			29			9
	Uncollectible accounts written-off, net of recovery			(63	)		(370	)
	Balance at end of year		$	288		$	322
	The significant uncollectible accounts written off in 2012 relate to previously recorded bad debts of our now discontinued Energy Services business.
Inventory, Policy [Policy Text Block]	'
	Inventories
	Inventories are stated at the lower of cost or market with cost determined under the first-in, first-out (FIFO) method.  We record provisions for excess, obsolete or slow-moving inventory based on changes in customer demand, technology developments or other economic factors.
Property, Plant and Equipment, Policy [Policy Text Block]	'
	Property, Plant and Equipment
	Property, plant and equipment are stated at cost.  Estimated useful lives are as follows:
	Buildings (years)		10	–	20
	Machinery and Equipment (years)		5	–	10
	Furniture and Fixtures (years)		3	–	10
	Computer Hardware and Software (years)		3	–	5
	Leasehold Improvements		Lesser of useful life or lease term
	Depreciation and amortization are computed using the straight-line method.  Betterments, renewals and extraordinary repairs that extend the life of the assets are capitalized.  Other repairs and maintenance costs are expensed when incurred.  When disposed, the cost and accumulated depreciation applicable to assets retired are removed from the accounts and the gain or loss on disposition is recognized in operating income (expense).
Goodwill and Intangible Assets, Policy [Policy Text Block]	'
	Long-Lived Assets, Goodwill and Intangibles
	We regularly assess all of our long-lived assets for impairment when events or circumstances indicate that their carrying amounts may not be recoverable.  For property, plant and equipment and amortizable intangible assets, this is accomplished by comparing the expected undiscounted future cash flows of the assets with the respective carrying amount as of the date of assessment.  Should aggregate future cash flows be less than the carrying value, a write-down would be required, measured as the difference between the carrying value and the fair value of the asset. Fair value is estimated either through the assistance of an independent valuation or as the present value of expected discounted future cash flows.  The discount rate used by us in our evaluation approximates our weighted average cost of capital.  If the expected undiscounted future cash flows exceed the respective carrying amount as of the date of assessment, no impairment is recognized.  We did not record any material impairments of long-lived assets in the years ended December 31, 2013 or 2012.
	In accordance with the Financial Accounting Standards Board’s (“FASB”) guidance for goodwill and other intangible assets, we do not amortize goodwill and intangible assets with indefinite lives, but instead measure these assets for impairment at least annually, or when events indicate that impairment exists. We amortize intangible assets that have definite lives so that the economic benefits of the intangible assets are being utilized over their weighted-average estimated useful life.
	The impairment analysis of goodwill consists first of a review of various qualitative factors of the identified reporting units to determine whether it is more likely than not that the fair value of a reporting unit exceeds its carrying amount, including goodwill. This review includes, but is not limited to, an evaluation of the macroeconomic, industry or market, and cost factors relevant to the reporting unit as well as financial performance and entity or reporting unit events that may affect the value of the reporting unit. If this review leads to the determination that it is more likely than not that the fair value of the reporting unit is greater than its carrying amount, further impairment testing is not required. However, if this review cannot support a conclusion that it is more likely than not that the fair value of the reporting unit is greater than its carrying amount, or at our discretion, quantitative impairment steps are performed. Similarly, the analysis for indefinite-lived intangible assets consists of review of various qualitative factors to determine if it is more likely than not that the indefinite-lived intangible asset is not impaired.  If a conclusion that it is more likely than not that the indefinite-lived asset is not impaired cannot be supported, or at our discretion, quantitative impairment steps are performed.
	The quantitative impairment test for goodwill consists of a comparison of the fair value of the reporting unit with the carrying amount of the reporting unit to which it is assigned.  If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired.  If the carrying amount of a reporting unit exceeds its fair value, a second step of the goodwill impairment test shall be performed to measure the amount of impairment loss, if any.  The impairment test for intangible assets with indefinite lives consists of a comparison of the fair value of the intangible assets with their carrying amounts. If the carrying value of the intangible assets exceeds the fair value, an impairment loss shall be recognized in an amount equal to that excess.  We determine the fair value of the reporting unit for goodwill impairment testing based on a discounted cash flow model.  We determine the fair value of our intangibles assets with indefinite lives (trademarks) through the royalty relief income valuation approach.
	There were no impairments of goodwill and intangible assets with indefinite lives in the years ended December 31, 2013 and 2012.
	Based on the final valuations for amortizable intangible assets acquired in the AMTI acquisition during 2009, and the ABLE and McDowell acquisitions during 2006, we project our amortization expense will be approximately $309, $229, $167, $122, and $86 for the fiscal years ending December 31, 2014 through 2018, respectively.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	'
	Translation of Foreign Currency
	The financial statements of our foreign subsidiaries are translated into U.S. dollar equivalents in accordance with FASB’s guidance for foreign currency translation, with translation adjustments recorded as a component of accumulated other comprehensive income.  Exchange losses relate to foreign currency transactions included in net loss for the years ended December 31, 2013 and 2012 were $15 and $43, respectively.
Revenue Recognition, Policy [Policy Text Block]	'
	Revenue Recognition
	Product Sales – In general, revenues from the sale of products are recognized when products are shipped. When products are shipped with terms that require transfer of title upon delivery at a customer’s location, revenues are recognized on the date of delivery.  A provision is made at the time the revenue is recognized for warranty costs expected to be incurred. Customers, including distributors, do not have a general right of return on products shipped.
	Technology Contracts – We recognize revenue using the proportional effort method based on the relationship of costs incurred to date to the total estimated cost to complete the contract. Elements of cost include direct material, labor and overhead.  If a loss on a contract is estimated, the full amount of the loss is recognized immediately.  We allocate costs to all technology contracts based upon actual costs incurred including an allocation of certain research and development costs incurred.
	Deferred Revenue – For each source of revenues, we defer recognition if: i) evidence of an agreement does not exist, ii) delivery or service has not occurred, iii) the selling price is not fixed or determinable, or iv) collectability is not reasonably assured.
Guarantees, Indemnifications and Warranties Policies [Policy Text Block]	'
	Warranty Reserves
	We estimate future costs associated with expected product failure rates, material usage and service costs in the development of our warranty obligations.  Warranty reserves, included in other current liabilities and other long-term liabilities as applicable on our Consolidated Balance Sheets, are based on historical experience of warranty claims.  In the event the actual results of these items differ from the estimates, an adjustment to the warranty obligation would be recorded.
Shipping and Handling Cost, Policy [Policy Text Block]	'
	Shipping and Handling Costs
	Costs incurred by us related to shipping and handling are included in cost of products sold.  Amounts charged to customers pertaining to these costs are reflected as revenue.
Advertising Costs, Policy [Policy Text Block]	'
	Advertising Expenses
	Advertising costs are expensed as incurred and are included in selling, general and administrative expenses in the accompanying Consolidated Statements of Operations.  Such expenses amounted to $413 and $538 for the years ended December 31, 2013 and 2012.
Research and Development Expense, Policy [Policy Text Block]	'
	Research and Development
	Research and development expenditures are charged to operations as incurred.  The majority of research and development expenses pertain to salaries and benefits, developmental supplies, depreciation and other contracted services.
	In 2011, we entered into a collaboration agreement with The New York State Energy Research and Development Authority (“NYSERDA”), to develop and demonstrate a large hybrid grid-connected energy storage system. This agreement was terminated by NYSERDA in the second quarter of 2013, per the terms of the agreement.  Pursuant to the terms of the agreement, NYSERDA reimbursed us for certain construction and project research and development costs.  During the year ended December 31, 2013, there were no recoveries from NYSERDA for construction costs and project research and development. During the year ended December 31, 2012, recoveries from NYSERDA for construction costs and project research and development costs were $91 and $11, respectively. Construction costs are reflected in the property, plant and equipment, net line on our Consolidated Balance Sheets and project research and development costs are reflected in the research and development line on our Consolidated Statements of Operations and Comprehensive Income (Loss).
	We plan to continue this project internally with smaller form batteries which provide greater opportunity and applicability in the markets we serve. However, due to the termination of the NYSERDA agreement and the resulting change in scope of the project, we performed a review of the details of costs capitalized in connection with this project to determine their future use. Those costs without an identifiable future use were written off in the second quarter of 2013 and totaled $56. The remaining capitalized costs were subjected to an impairment test based upon forecasted future cash flows, in accordance with current accounting guidance. No impairment charge was taken on the remaining capitalized costs.
Environmental Costs, Policy [Policy Text Block]	'
	Environmental Costs
	Environmental expenditures that relate to current operations are expensed or capitalized, as appropriate, in accordance with FASB’s guidance on environmental remediation liabilities.  Remediation costs that relate to an existing condition caused by past operations are accrued when it is probable that these costs will be incurred and can be reasonably estimated.
Income Tax, Policy [Policy Text Block]	'
	Income Taxes
	The asset and liability method, prescribed by FASB’s guidance for the Accounting for Income Taxes, is used in accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse.
	A valuation allowance is required when it is more likely than not that the recorded value of a deferred tax asset will not be realized.   As of December 31, 2013, we continue to recognize a valuation allowance in the U.S. and U.K. on our net U.S. deferred tax asset to the extent the differences and the U.S. and U.K. NOLs resulting in the deferred tax asset are not able to be offset by future reversing temporary differences, based on a consistent evaluation methodology that was used for 2012.  The assessment of the realizability of the U.S. NOL was based on a number of factors including, our history of net operating losses, the volatility of our earnings, our historical operating volatility, our historical inability to accurately forecast earnings for future periods and the continued uncertainty of the general business climate as of the end of 2013.   We concluded that these factors represent sufficient negative evidence and have concluded that we should record a full valuation allowance under FASB’s guidance on the accounting for income taxes.  We also recorded a valuation allowance on our net deferred tax asset for the year ended December 31, 2012.
	We have adopted the provisions of FASB’s guidance for the Accounting for Uncertainty in Income Taxes.  In 2013 and 2012, we had unrecognized tax benefits related to uncertain tax positions which have been recorded as a decrease in our NOL.  We have not recorded any interest or penalty in regard to any unrecognized benefit.  Interest and penalties would begin to accrue in the period in which the NOL’s related to the uncertain tax positions are utilized.  Our policy regarding interest and/or penalties related to income tax matters is to recognize such items as a component of income tax expense (benefit).
Concentration Risk, Credit Risk, Policy [Policy Text Block]	'
	Concentration Related to Customers and Suppliers
	During the years ended December 31, 2013 and 2012, we had one major customer, a large defense primary contractor, which comprised 25% and 21% of our revenues, respectively.  There were no other customers that comprised greater than 10% of our total revenues during these years.
	We have two customers who comprised 26% and 15%, respectively, of our trade accounts receivable as of December 31, 2013. We had two customers who comprised 22% and 12%, respectively, of our trade accounts receivable as of December 31, 2012.
	Currently, we do not experience significant seasonal trends in our revenues.  Since a significant portion of our revenues are based on purchases from U.S. and allied country defense departments, the timing of our sales could be impacted by delays in the government budget process and the decisions to deploy resources to support military purchases of our products.
	We generally do not distribute our products to a concentrated geographical area nor is there a significant concentration of credit risks arising from individuals or groups of customers engaged in similar activities, or who have similar economic characteristics. While direct and indirect sales to the U.S. Department of Defense have been substantial during 2013 and 2012, we do not consider this customer to be a significant credit risk.   We do not normally obtain collateral on trade accounts receivable.
	Certain materials and components used in our products are available only from a single or a limited number of suppliers. As such, some materials and components could become in short supply resulting in limited availability and/or increased costs. Additionally, we may elect to develop relationships with a single or limited number of suppliers for materials and components that are otherwise generally available.  Although we believe that alternative suppliers are available to supply materials and components that could replace materials and components currently used and that, if necessary, we would be able to redesign our products to make use of such alternatives, any interruption in the supply from any supplier that serves as a sole source could delay product shipments and have a material adverse effect on our business, financial condition and results of operations.  We have experienced interruptions of product deliveries by sole source suppliers in the past.
Fair Value Measurement, Policy [Policy Text Block]	'
	Fair Value Measurements and Disclosures
	The FASB guidance for fair value measurements provides a framework for measuring fair value and requires expanded disclosures regarding fair value measurements. Fair value is defined as the price that would be received for an asset or the exit price that would be paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. This accounting standard established a fair value hierarchy, which requires an entity to maximize the use of observable inputs, where available. The following summarizes the three levels of inputs required.
	Level 1:	Quoted prices in active markets for identical assets or liabilities.
	Level 2:	Observable inputs, other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or that we corroborate with observable market data for substantially the full term of the related assets or liabilities.
	Level 3:	Unobservable inputs supported by little or no market activity that are significant to the fair value of the assets or liabilities.
	FASB’s guidance for the disclosure regarding fair value of financial instruments requires disclosure of an estimate of the fair value of certain financial instruments.  The fair value of financial instruments pursuant to FASB’s guidance for the disclosure regarding fair value of financial instruments approximated their carrying values at December 31, 2013 and 2012.  The fair value of cash, trade accounts receivable, trade accounts payable, accrued liabilities, and our revolving credit facility approximates carrying value due to the short-term nature of these instruments.  The estimated fair value of other long-term debt and capital lease obligations approximates carrying value due to the variable nature of the interest rates or the stated interest rates approximating current interest rates that are available for debt with similar terms.
Earnings Per Share, Policy [Policy Text Block]	'
	Earnings (Loss) Per Share
	We have adopted the provisions of FASB’s guidance for determining whether instruments granted in share-based payment transactions are participating securities.  The guidance requires that all outstanding unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (such as restricted stock awards granted by us) be considered participating securities.  Because the restricted stock awards are participating securities, we are required to apply the two-class method of computing basic and diluted earnings per share (the “Two-Class Method”).
	Basic EPS is determined using the Two-Class Method and is computed by dividing earnings attributable to Ultralife common shareholders by the weighted-average shares outstanding during the period.  The Two-Class Method is an earnings allocation formula that determines earnings per share for each class of common stock and participating security according to dividends declared and participation rights in undistributed earnings.  Diluted EPS includes the dilutive effect of securities, if any, and reflects the more dilutive EPS amount calculated using the treasury stock method or the Two-Class Method.  For the years ended December 31, 2013 and 2012, both the Two-Class Method and the treasury stock method calculations for diluted EPS yielded the same result.
	The computation of basic and diluted earnings per share is summarized as follows:
			Years Ended December 31,
			2013			2012
	Net Loss from continuing operations attributable to Ultralife		$	(1,054	)	$	(1,097	)
	Net Loss from continuing operations attributable to participating securities (unvested restricted stock awards) (120,000 and -0- shares, respectively)			-			-
	Net Loss from continuing operations attributable to Ultralife common shareholders (a)			(1,054	)		(1,097	)
	Net Income (Loss) from discontinued operations attributable to Ultralife common shareholders (c)		$	128		$	(501	)
	Average Common Shares Outstanding – Basic (e)			17,465,000			17,403,000
	Effect of Dilutive Securities:
	Stock Options / Warrants			-			-
	Average Common Shares Outstanding – Diluted (f)			17,465,000			17,403,000
	EPS – Basic (a/e) – continuing operations		$	(0.06	)	$	(0.06	)
	EPS – Basic (c/e) – discontinued operations		$	0.01		$	(0.03	)
	EPS – Diluted (b/f) – continuing operations		$	(0.06	)	$	(0.06	)
	EPS – Diluted (d/f) – discontinued operations		$	0.01		$	(0.03	)
	There were 2,251,622 outstanding stock options, warrants and restricted stock awards as of December 31, 2013, that were not included in EPS as the effect would have been anti-dilutive. No outstanding stock options, warrants and restricted stock awards were included in the dilution computation for the year ended December 31, 2013. There were 2,211,488 outstanding stock options, warrants and restricted stock awards as of December 31, 2012, that were not included in EPS as the effect would have been anti-dilutive. No outstanding stock options, warrants and restricted stock awards were included in the dilution computation for the year ended December 31, 2012.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	'
	Stock-Based Compensation
	We have various stock-based employee compensation plans, which are described more fully in Note 7.   We follow the provisions of FASB’s guidance on share-based payments, which requires that compensation cost relating to share-based payment transactions be recognized in the financial statements.  The cost is measured at the grant date, based on the fair value of the award, and is recognized as an expense over the employee’s requisite service period (generally the vesting period of the equity award).
Segment Reporting, Policy [Policy Text Block]	'
	Segment Reporting
	We report segment information in accordance with FASB’s guidance on Disclosures about Segments of an Enterprise and Related Information.   We have two operating segments.  The basis for determining our operating segments is the manner in which financial information is used by us in our operations.  Management operates and organizes itself according to business units that comprise unique products and services across geographic locations.
	On February 15, 2012, we decided to divest our RedBlack Communications business, which previously was reported in the Communications Systems segment.  Further, in Q4 of 2012, we elected not to renew the lease for our U.K. manufacturing facility which expired on March 24, 2013. The results of the discontinued UK operations were previously reported in the Battery and Energy Products segment. See Note 2 in these Notes to Consolidated Financial Statements for additional information.
New Accounting Pronouncements, Policy [Policy Text Block]	'
	Recent Accounting Pronouncements
	In July 2013, the FASB issued ASU 2013-11 “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss or a Tax Credit Carryforward Exists.” With certain exceptions, ASU 2013-11 requires entities to present an unrecognized tax benefit, or portion of an unrecognized tax benefit, as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward. The guidance is effective for interim and annual periods beginning after December 15, 2013 on either a prospective or retrospective basis with early adoption permitted. We do not expect adoption of this guidance to have a material impact on its consolidated results of operations and financial condition.
	In March 2013, the FASB issued ASU 2013-05, “Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity.” ASU 2013-05 provides that the cumulative translation adjustment is released into net income when a reporting entity ceases to have a controlling interest in a subsidiary that is controlled by a consolidated foreign entity. Further, this update states that the sale of an investment in a foreign entity includes both events that result in the loss of a controlling financial interest in a foreign entity, regardless of any retained investment, and events that result in an acquirer obtaining control through a step acquisition. ASU 2013-05 is effective prospectively for fiscal years beginning after December 15, 2013, with early adoption permitted. We do not believe that adoption of this standard will have a material impact on our consolidated results of operations and financial condition.
	In February 2013, the FASB issued ASU 2013-04 “Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation is Fixed at the Reporting Date.” ASU 2013-04 requires an entity to measure such obligations as the sum of the amount that the reporting entity agreed to pay on the basis of its arrangement with co-obligors and any additional amount the reporting entity expects to pay on behalf of its co-obligors. The guidance is effective for interim and annual periods beginning after December 15, 2013. Retrospective presentation for all comparative periods presented is required with early adoption permitted. We do not expect adoption of this guidance to have a material impact on its consolidated results of operations and financial condition.
	In February 2013, the FASB issued ASU 2013-02, “Reporting of Amounts Reclassified out of Accumulated Other Comprehensive Income.” ASU 2013-02 requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component as well as presentation, either on the face of the financial statement or in the notes, of significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional detail about those amounts. ASU 2013-02 is effective for fiscal years beginning after December 15, 2012. Adoption of this standard did not have a material impact on our consolidated results of operations and financial condition.
