Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated condensed financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments except those otherwise described herein) considered necessary for a fair presentation have been included, unless otherwise disclosed. Operating results for the three and six months ended October 2, 2022 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2023. The Consolidated Condensed Balance Sheet at March 31, 2022 has been derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. The financial statements should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in the Company’s 2022 Annual Report on Form 10-K (SEC File No. 001-32253), which was filed on May 25, 2022 (the “2022 Annual Report”). EnerSys (the “Company”) reports interim financial information for 13-week periods, except for the first quarter, which always begins on April 1, and the fourth quarter, which always ends on March 31. The four quarters in fiscal 2023 end on July 3, 2022, October 2, 2022, January 1, 2023, and March 31, 2023, respectively. The four quarters in fiscal 2022 ended on July 4, 2021, October 3, 2021, January 2, 2022, and March 31, 2022, respectively. The consolidated condensed financial statements include the accounts of the Company and its wholly-owned subsidiaries and any partially owned subsidiaries that the Company has the ability to control. All intercompany transactions and balances have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. These estimates and assumptions take into account historical and forward looking factors that the Company believes are reasonable, including, but not limited to, the potential impacts arising from the coronavirus pandemic including its variants (“COVID-19”) and public and private sector policies and initiatives aimed at reducing its transmission. As the extent and duration of the impacts of COVID-19 remain unclear, the Company’s estimates and assumptions may evolve as conditions change. Actual results could differ significantly from those estimates. Examples of significant estimates include the allowance for credit losses, the recoverability of property, plant and equipment, the incremental borrowing rate for lease liabilities, the recoverability of intangible assets and other long-lived assets, fair value measurements, including those related to financial instruments, goodwill and intangible assets, valuation allowances on tax assets, pension and postretirement benefit obligations, contingencies and the identification and valuation of assets acquired and liabilities assumed in connection with business combinations.

Revenue Recognition

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition The Company’s revenues by reportable segments are presented in Note 17 and are consistent with how we organize and manage our operations, as well as product line net sales information. Service revenues related to the work performed for the Company’s customers by its maintenance technicians generally represent a separate and distinct performance obligation. Control for these services passes to the customer as the services are performed. Service revenues for the second quarter of fiscal 2023 and 2022 amounted to $100,990 and $90,112, respectively. Service revenues for the six months of fiscal 2023 and 2022 amounted to $200,814 and $172,630, respectively. A small portion of the Company's customer arrangements oblige the Company to create customized products for its customers that require combining both products and services into a single performance obligation because the individual products and services that are required to fulfill the customer requirements do not meet the definition for a distinct performance obligation. These customized products generally have no alternative use to the Company and the terms and conditions of these arrangements give the Company the enforceable right to payment for performance completed to date, including a reasonable profit margin. For these arrangements, control transfers over time and the Company measures progress towards completion by selecting the input or output method that best depicts the transfer of control of the underlying goods and services to the customer for each respective arrangement. Methods used by the Company to measure progress toward completion include labor hours, costs incurred and units of production. Revenues recognized over time for the second quarter of fiscal 2023 and 2022 amounted to $56,202 and $43,607, respectively. Revenues recognized over time for the six months of fiscal 2023 and 2022 amounted to $113,206 and $84,511, respectively. On October 2, 2022, the aggregate transaction price allocated to unsatisfied (or partially unsatisfied) performance obligations was approximately $167,127, of which, the Company estimates that approximately $125,736 will be recognized as revenue in fiscal 2023, $37,152 in fiscal 2024, and $4,239 in fiscal 2025. Any payments that are received from a customer in advance, prior to the satisfaction of a related performance obligation and billings in excess of revenue recognized, are deferred and treated as a contract liability. Advance payments and billings in excess of revenue recognized are classified as current or non-current based on the timing of when recognition of revenue is expected. As of October 2, 2022, the current and non-current portion of contract liabilities were $23,995 and $1,232, respectively. As of March 31, 2022, the current and non-current portion of contract liabilities were $27,870 and $1,387, respectively. Revenues recognized during the second quarter of fiscal 2023 and 2022 that were included in the contract liability at the beginning of the quarter, amounted to $5,832 and $5,467, respectively. Revenues recognized during the six months of fiscal 2023 and 2022 that were included in the contract liability at the beginning of the year, amounted to $6,877 and $5,182, respectively. Amounts representing work completed and not billed to customers represent contract assets and were $64,824 and $59,924 as of October 2, 2022 and March 31, 2022, respectively. The Company uses historic customer product return data as a basis of estimation for customer returns and records the reduction of sales at the time revenue is recognized. At October 2, 2022, the right of return asset related to the value of inventory anticipated to be returned from customers was $4,605 and refund liability representing amounts estimated to be refunded to customers was $8,831.

Fair Value of Financial Instruments	Fair Value of Financial Instruments Recurring Fair Value Measurements The following tables represent the financial assets and (liabilities) measured at fair value on a recurring basis as of October 2, 2022 and March 31, 2022, and the basis for that measurement: Total Fair Value Measurement October 2, 2022 Quoted Price in Significant Significant Lead forward contracts $ (942) $ — $ (942) $ — Foreign currency forward contracts 1,628 — 1,628 — Net investment hedges (3,498) — (3,498) — Total derivatives $ (2,812) $ — $ (2,812) $ — Total Fair Value Measurement March 31, 2022 Quoted Price in Significant Significant Lead forward contracts $ 2,520 $ — $ 2,520 $ — Foreign currency forward contracts (256) — (256) — Net investment hedges 298 — 298 — Total derivatives $ 2,562 $ — $ 2,562 $ — The fair values of lead forward contracts are calculated using observable prices for lead as quoted on the London Metal Exchange (“LME”) and, therefore, were classified as Level 2 within the fair value hierarchy, as described in Note 1- Summary of Significant Accounting Policies to the Company's Consolidated Financial Statements included in the 2022 Annual Report. The fair values for foreign currency forward contracts and net investment hedges are based upon current quoted market prices and are classified as Level 2 based on the nature of the underlying market in which these derivatives are traded. Financial Instruments The fair values of the Company’s cash and cash equivalents approximate carrying value due to their short maturities. The fair value of the Company’s short-term debt and borrowings under the Second Amended Credit Facility (as defined in Note 12), approximate their respective carrying value, as they are variable rate debt and the terms are comparable to market terms as of the balance sheet dates and are classified as Level 2. In fiscal 2020, the Company issued its 4.375% Senior Notes due December 15, 2027 (the “2027 Notes”), with an original face value of $300,000. The Company's 5.00% Senior Notes due April 30, 2023 (the “2023 Notes”), with an original face value of $300,000, were issued in fiscal 2016. The fair value of the 2027 Notes and 2023 Notes (collectively, the “Senior Notes”) represent the trading values based upon quoted market prices and are classified as Level 2. The 2027 Notes were trading at approximately 88% and 95% of face value on October 2, 2022 and March 31, 2022, respectively. The 2023 Notes were trading at approximately 99% and 101% of face value on October 2, 2022 and March 31, 2022, respectively. The carrying amounts and estimated fair values of the Company’s derivatives and Senior Notes at October 2, 2022 and March 31, 2022 were as follows: October 2, 2022 March 31, 2022 Carrying Fair Value Carrying Fair Value Financial assets: Derivatives (1) $ (2,812) $ (2,812) $ 2,562 $ 2,562 Financial liabilities: Senior Notes (2) $ 600,000 $ 561,750 $ 600,000 $ 585,750 (1) Represents lead, foreign currency forward contracts and net investment hedges (see Note 7 for asset and liability positions of the lead, foreign currency forward contracts and net investment hedges at October 2, 2022 and March 31, 2022). (2) The fair value amount of the Senior Notes at October 2, 2022 and March 31, 2022 represent the trading value of the instruments. Non-recurring fair value measurements On June 29, 2022, the Company committed to a plan to close its facility in Ooltewah, Tennessee, which focused on manufacturing flooded motive power batteries for electric forklifts. Management determined that future demand for traditional motive power flooded cells will decrease as customers transition to maintenance free product solutions in lithium and Thin Plate Pure Lead (TPPL). As a result, the Company concluded that the carrying value of the asset group was not recoverable and recorded during the first quarter of fiscal 2023 a write-off of $7,300 of the fixed assets, for which there is expected to be no salvageable value. The valuation technique used to measure the fair value of fixed assets was a combination of the income and market approaches. The inputs used to measure the fair value of these fixed assets under the income approach were largely unobservable and accordingly were classified as Level 3.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments The Company utilizes derivative instruments to reduce its exposure to fluctuations in commodity prices, foreign exchange rates and interest, under established procedures and controls. The Company does not enter into derivative contracts for speculative purposes. The Company’s agreements are with creditworthy financial institutions and the Company anticipates performance by counterparties to these contracts and therefore no material loss is expected. Derivatives in Cash Flow Hedging Relationships Lead Forward Contracts The Company enters into lead forward contracts to fix the price for a portion of its lead purchases. Management considers the lead forward contracts to be effective against changes in the cash flows of the underlying lead purchases. The vast majority of such contracts are for a period not extending beyond one year. At October 2, 2022 and March 31, 2022, the Company has hedged the price to purchase approximately 67.5 million pounds and 54.0 million pounds of lead, respectively, for a total purchase price of $59,429 and $56,768, respectively. Foreign Currency Forward Contracts The Company uses foreign currency forward contracts and options to hedge a portion of the Company’s foreign currency exposures for lead, as well as other foreign currency exposures so that gains and losses on these contracts offset changes in the underlying foreign currency denominated exposures. The vast majority of such contracts are for a period not extending beyond one year. As of October 2, 2022 and March 31, 2022, the Company had entered into a total of $35,916 and $29,676, respectively, of such contracts. Derivatives in Net Investment Hedging Relationships Net Investment Hedges The Company uses cross currency fixed interest rate swaps to hedge its net investments in foreign operations against future volatility in the exchange rates between the U.S. Dollar and euro. On September 29, 2022, the Company terminated its $300,000 cross-currency fixed interest rate swap contracts, originally entered into on December 23, 2021, and received a net settlement of $43,384. The cash proceeds have been included in Proceeds from termination of net investment hedges in our Consolidated Condensed Statements of Cash Flows. On September 29, 2022, the Company entered into a cross-currency fixed interest rate swap contracts with an aggregate notional amount of $150,000, maturing on December 15, 2027. The cross-currency fixed interest rate swap contracts qualify for hedge accounting as a net investment hedging instrument, which allows for them to be remeasured to foreign currency translation adjustment within AOCI (“Accumulated Other Comprehensive Income”) to offset the translation risk from those investments. Balances in the foreign currency translation adjustment accounts remain until the sale or substantially complete liquidation of the foreign entity, upon which they are recognized as a component of income (expense). Impact of Hedging Instruments on AOCI In the coming twelve months, the Company anticipates that $2,378 of pretax loss relating to lead, foreign currency forward contracts and net investment hedges will be reclassified from AOCI as part of cost of goods sold and interest expense. This amount represents the current net unrealized impact of hedging lead, foreign exchange rates and interest rates, which will change as market rates change in the future. This amount will ultimately be realized in the Consolidated Condensed Statements of Income as an offset to the corresponding actual changes in lead, foreign exchange rates and interest costs resulting from variable lead cost, foreign exchange and interest rates hedged. Derivatives not Designated in Hedging Relationships Foreign Currency Forward Contracts The Company also enters into foreign currency forward contracts to economically hedge foreign currency fluctuations on intercompany loans and foreign currency denominated receivables and payables. These are not designated as hedging instruments and changes in fair value of these instruments are recorded directly in the Consolidated Condensed Statements of Income. As of October 2, 2022 and March 31, 2022, the notional amount of these contracts was $52,128 and $22,990, respectively.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s income tax provision consists of federal, state and foreign income taxes. The tax provision for the second quarter of fiscal 2023 and 2022 was based on the estimated effective tax rates applicable for the full years ending March 31, 2023 and March 31, 2022, respectively, after giving effect to items specifically related to the interim periods. The Company’s effective income tax rate with respect to any period may be volatile based on the mix of income in the tax jurisdictions, in which the Company operates, change in tax laws and the amount of the Company's consolidated earnings before taxes. The consolidated effective income tax rates for the second quarter of fiscal 2023 and 2022 were 14.4% and 10.8% and for the six months of fiscal 2023 and 2022 were 15.0% and 13.7%, respectively. The rate increase in the second quarter and six months of fiscal 2023 compared to the prior year periods are primarily due to discrete tax items and changes in mix of earnings among tax jurisdictions.

Commitments and Contingencies Disclosure [Abstract]
Commitments, Contingencies and Litigation	Commitments, Contingencies and Litigation Litigation and Other Legal Matters In the ordinary course of business, the Company and its subsidiaries are routinely defendants in or parties to pending and threatened legal actions and proceedings, including actions brought on behalf of various classes of claimants. These actions and proceedings are generally based on alleged violations of environmental, anticompetition, employment, contract and other laws. In some of these actions and proceedings, claims for substantial monetary damages are asserted against the Company and its subsidiaries. In the ordinary course of business, the Company and its subsidiaries are also subject to regulatory and governmental examinations, information gathering requests, inquiries, investigations, and threatened legal actions and proceedings. In connection with formal and informal inquiries by federal, state, local and foreign agencies, the Company and its subsidiaries receive numerous requests, subpoenas and orders for documents, testimony and information in connection with various aspects of their activities. European Competition Investigations Certain of the Company’s European subsidiaries had received subpoenas and requests for documents and, in some cases, interviews from, and have had on-site inspections conducted by, the competition authorities of Belgium, Germany and the Netherlands relating to conduct and anticompetitive practices of certain industrial battery participants. For additional information regarding these matters, see Note 19 - Commitments, Contingencies and Litigation to the Consolidated Financial Statements contained in the 2022 Annual Report. As of October 2, 2022 and March 31, 2022, the Company did not have a reserve balance related to these matters. The precise scope, timing and time period at issue, as well as the final outcome of the investigations or customer claims, remain uncertain. Accordingly, the Company’s estimate may change from time to time, and actual losses could vary. Environmental Issues As a result of its operations, the Company is subject to various federal, state, and local, as well as international environmental laws and regulations and is exposed to the costs and risks of registering, handling, processing, storing, transporting, and disposing of hazardous substances, especially lead and acid. The Company’s operations are also subject to federal, state, local and international occupational safety and health regulations, including laws and regulations relating to exposure to lead in the workplace. The Company believes that it has adequate reserves to satisfy its environmental liabilities. Lead, Foreign Currency Forward Contracts and Swaps To stabilize its lead costs and reduce volatility from currency and interest rate movements, the Company entered into contracts with financial institutions. The vast majority of lead and foreign currency contracts are for a period not extending beyond one year. The Company also entered into a cross currency fixed interest rate swap agreement, maturing on December 15, 2027, to hedge its net investments in foreign operations against future volatility in the exchange rates between the U.S. Dollar and euro.

Restructuring and exit charges for the second quarter and six months of fiscal 2023 by reportable segments are as follows: Quarter ended October 2, 2022 Energy Systems Motive Power Specialty Total Restructuring charges $ 777 $ 152 $ — $ 929 Exit charges — 2,336 — 2,336 Restructuring and other exit charges $ 777 $ 2,488 $ — $ 3,265 Six months ended October 2, 2022 Energy Systems Motive Power Specialty Total Restructuring charges $ 939 $ 152 $ — $ 1,091 Exit charges — 10,502 — 10,502 Restructuring and other exit charges $ 939 $ 10,654 $ — $ 11,593 A roll-forward of the restructuring reserve, excluding exit charges, is as follows: Balance as of March 31, 2022 $ 1,030 Accrued 1,091 Costs incurred (736) Foreign currency impact (92) Balance as of October 2, 2022 $ 1,293 Exit Charges Fiscal 2023 Program On June 29, 2022, the Company committed to a plan to close its facility in Ooltewah, Tennessee, which produces flooded motive power batteries for electric forklifts. Management determined that future demand for traditional motive power flooded cells will decrease as customers transition to maintenance free product solutions in lithium and TPPL. The Company currently estimates that the total charges for these actions will amount to approximately $18,500. Cash charges for employee severance related payments, cleanup related to the facility, contractual releases and legal expenses are estimated to be $9,200 and non-cash charges from inventory and fixed asset write-offs are estimated to be $9,300. These actions will result in the reduction of approximately 165 employees. The plan is expected to be completed by calendar 2023. During the six months of fiscal 2023, the Company recorded cash charges relating primarily to severance of $1,577 and non-cash charges of $7,261 relating to fixed asset write-offs. The Company also recorded a non-cash write off relating to inventories of $1,544, which was reported in cost of goods sold. Fiscal 2022 Program Hagen, Germany In fiscal 2021, the Company's Board of Directors approved a plan to close substantially all of its facility in Hagen, Germany, which produces flooded motive power batteries for electric forklifts. Management determined that future demand for the motive power batteries produced at this facility was not sufficient, given the conversion from flooded to maintenance free batteries by customers, the existing number of competitors in the market, as well as the near term decline in demand and increased uncertainty from the pandemic. The Company plans to retain the facility with limited sales, service and administrative functions along with related personnel for the foreseeable future. The Company currently estimates that the total charges for these actions will amount to approximately $60,000, of which cash charges for employee severance related payments, cleanup related to the facility, contractual releases and legal expenses were estimated to be $40,000 and non-cash charges from inventory and equipment write-offs were estimated to be $20,000. The majority of these charges were recorded as of October 2, 2022. These actions resulted in the reduction of approximately 200 employees. During fiscal 2021, the Company recorded cash charges relating to severance of $23,331 and non-cash charges of $7,946 primarily relating to fixed asset write-offs. During fiscal 2022, the Company recorded cash charges primarily relating to severance of $8,069 and non-cash charges of $3,522 primarily relating to fixed asset write-offs. The Company also recorded a non-cash write off relating to inventories of $960, which was reported in cost of goods sold. During the six months of fiscal 2023, the Company recorded cash charges of $1,351 relating to site cleanup and $276 of non-cash charges relating to accelerated depreciation of fixed assets. Targovishte, Bulgaria During fiscal 2019, the Company committed to a plan to close its facility in Targovishte, Bulgaria, which produced diesel-electric submarine batteries. Management determined that the future demand for batteries of diesel-electric submarines was not sufficient given the number of competitors in the market. Of the estimated total charges of $26,000 for this plan, the Company had recorded charges amounting to $20,242 in fiscal 2019, relating to severance and inventory and fixed asset write-offs and an additional $5,123 relating to cash and non-cash charges during fiscal 2020. During fiscal 2021, in keeping with its strategy of exiting the manufacture of batteries for diesel-electric submarines, the Company completed further actions which resulted in $220 relating to cash and non-cash charges. During the six months of fiscal 2022, the Company sold this facility for $1,489. A net gain of $1,208 was recorded as a credit to exit charges in the Consolidated Condensed Statement of Income.

The 2017 Credit Facility was scheduled to mature on September 30, 2022, initially comprised a $600,000 senior secured revolving credit facility (“2017 Revolver”) and a $150,000 senior secured term loan (“2017 Term Loan”). The Company utilized the borrowings from the 2017 Credit Facility to repay its pre-existing credit facility. In fiscal 2019, the Company amended the 2017 Credit Facility (as amended, the “Amended Credit Facility”) to fund the Alpha acquisition. The Amended Credit Facility consisted of $449,105 senior secured term loans (the “Amended Term Loan”), including a CAD 133,050 ($99,105) senior secured term loan and a $700,000 senior secured revolving credit facility (the “Amended Revolver”). The amendment resulted in an increase of the 2017 Term Loan and the 2017 Revolver by $299,105 and $100,000, respectively. During the second quarter of fiscal 2022, the Company entered into a second amendment to the 2017 Credit Facility (as amended, the “Second Amended Credit Facility”). The Second Amended Credit Facility, scheduled to mature on September 30, 2026, consists of a $130,000 senior secured term loan (the “Second Amended Term Loan”), a CAD 106,440 ($84,229) senior secured term loan and an $850,000 senior secured revolving credit facility (the “Second Amended Revolver”). The second amendment resulted in a decrease of the Amended Term Loan by $150,000 and an increase of the Amended Revolver by $150,000. The quarterly installments payable on the Second Amended Term Loan are $2,589 beginning December 31, 2022, $3,883 beginning December 31, 2024 and $5,178 beginning December 31, 2025 with a final payment of $155,339 on September 30, 2026. Both the Second Amended Revolver and the Second Amended Term Loan bear interest, at the Company's option, at a rate per annum equal to either (i) the London Interbank Offered Rate (“LIBOR”) or Canadian Dollar Offered Rate (“CDOR”) plus (i) LIBOR plus between 1.125% and 2.25% (currently 1.75% and based on the Company's consolidated total net leverage ratio) or (ii) the U.S. Dollar Base Rate plus between 0.125% and 1.25%, (currently 0.75% and based on the Company's consolidated total net leverage ratio) which equals, for any day a fluctuating rate per annum equal to the highest of (a) the Federal Funds Effective Rate plus 0.50%, (b) Bank of America “Prime Rate” and (c) the Eurocurrency Base Rate plus 1%; provided that, if the Base Rate shall be less than zero, such rate shall be deemed zero (iii) the CDOR Base Rate equal to the higher of (a) Bank of America “Prime Rate” and (b) average 30-day CDOR rate plus 0.50%. The Third Amended Credit Facility (defined below) provides for alternate benchmark rates such as the Secured Overnight Financing Rate (“SOFR”) to replace LIBOR when it is phased out. During the second quarter of fiscal 2023, the Company entered into a third amendment to the 2017 Credit Facility (as amended, the “Third Amended Credit Facility”). The Third Amended Credit Facility provides a new incremental delayed-draw senior secured term loan up to $300,000 (the “Third Amended Term Loan”), which shall be available to draw at any time until March 15, 2023. Once drawn, the funds will mature on September 30, 2026, the same as the Company's Second Amended Term loan and Second Amended Revolver. In connection with the agreement, the Company incurred $1,161 in third party administrative and legal fees recognized in interest expense and capitalized $1,096 in charges from existing lenders as a deferred asset. The Third Amended Credit Facility may be increased by an aggregate amount of $350,000 in revolving commitments and / or one or more new tranches of term loans, under certain conditions. The Third Amended Term Loan bears interest, at the Company's option, at a rate per annum equal to either (i) the Secured Overnight Financing Rate (“SOFR”) plus 10 basis points plus (i) SOFR plus between 1.375% and 2.50% or (ii) the U.S. Dollar Base Rate plus between 0.375% and 1.50%, which equals, for any day a fluctuating rate per annum equal to the highest of (a) the Federal Funds Effective Rate plus 0.50%, (b) Bank of America “Prime Rate” and (c) the Term SOFR plus 1%; provided that, if the Base Rate shall be less than zero, such rate shall be deemed zero). Until the funds are drawn, the Company must pay a commitment fee of 0.175% to 0.35% (currently 0.30% and based on the Company's consolidated total net leverage ratio) at a rate per annum on the unused portion. Obligations under the Third Amended Credit Facility are secured by substantially all of the Company’s existing and future acquired assets, including substantially all of the capital stock of the Company’s United States subsidiaries that are guarantors under the Third Amended Credit Facility and up to 65% of the capital stock of certain of the Company’s foreign subsidiaries that are owned by the Company’s United States subsidiaries. The Third Amended Credit Facility allows for up to two temporary increases in the maximum leverage ratio to 4.50x from 4.00x to 4.25x for a four quarter period following an acquisition larger than $250,000. Effective with the Third Amended Credit Facility, the maximum leverage ratio increased from 3.50x to 4.25x effective to the last day of the second quarter of fiscal year 2024 and decreasing subsequently to 4.00x. As of October 2, 2022, the Company had $495,000 outstanding under the Second Amended Revolver, $207,119 under the Second Amended Term Loan, and none outstanding under the Third Amended Term Loan. Current Portion of Debt The current portion of the Second Amended Term Loan and the 2023 Notes are $10,358 and $300,000, respectively, and are classified as long-term debt, as the Company expects to refinance the future quarterly payments with borrowings under the Second Amended Revolver and redemption of the 2023 Notes with borrowings under the Third Amended Term Loan. Short-Term Debt As of October 2, 2022 and March 31, 2022, the Company had $34,581 and $55,084, respectively, of short-term borrowings. The weighted average interest rate on these borrowings was approximat ely 6.2% and 2.4%, respectively, at October 2, 2022 and March 31, 2022. Letters of Credit As of October 2, 2022 and March 31, 2022, the Company had $3,229 and $2,959 of standby letters of credit, respectively. Debt Issuance Costs In connection with the Second Amended Credit Facility, the Company capitalized $2,952 in debt issuance costs and wrote off $128 of unamortized debt issuance costs. Amortization expense, relating to debt issuance costs, included in interest expense was $487 and $615, respectively, for the second quarter ended October 2, 2022 and October 3, 2021 and $974 and $1,133 for the six months of fiscal 2023 and 2022, respectively.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated condensed financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments except those otherwise described herein) considered necessary for a fair presentation have been included, unless otherwise disclosed. Operating results for the three and six months ended October 2, 2022 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2023. The Consolidated Condensed Balance Sheet at March 31, 2022 has been derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. The financial statements should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in the Company’s 2022 Annual Report on Form 10-K (SEC File No. 001-32253), which was filed on May 25, 2022 (the “2022 Annual Report”). EnerSys (the “Company”) reports interim financial information for 13-week periods, except for the first quarter, which always begins on April 1, and the fourth quarter, which always ends on March 31. The four quarters in fiscal 2023 end on July 3, 2022, October 2, 2022, January 1, 2023, and March 31, 2023, respectively. The four quarters in fiscal 2022 ended on July 4, 2021, October 3, 2021, January 2, 2022, and March 31, 2022, respectively. The consolidated condensed financial statements include the accounts of the Company and its wholly-owned subsidiaries and any partially owned subsidiaries that the Company has the ability to control. All intercompany transactions and balances have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. These estimates and assumptions take into account historical and forward looking factors that the Company believes are reasonable, including, but not limited to, the potential impacts arising from the coronavirus pandemic including its variants (“COVID-19”) and public and private sector policies and initiatives aimed at reducing its transmission. As the extent and duration of the impacts of COVID-19 remain unclear, the Company’s estimates and assumptions may evolve as conditions change. Actual results could differ significantly from those estimates. Examples of significant estimates include the allowance for credit losses, the recoverability of property, plant and equipment, the incremental borrowing rate for lease liabilities, the recoverability of intangible assets and other long-lived assets, fair value measurements, including those related to financial instruments, goodwill and intangible assets, valuation allowances on tax assets, pension and postretirement benefit obligations, contingencies and the identification and valuation of assets acquired and liabilities assumed in connection with business combinations.
