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 1, 2023 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2024. The Consolidated Condensed Balance Sheet at March 31, 2023 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 2023 Annual Report on Form 10-K (SEC File No. 001-32253), which was filed on May 25, 2023 (the “2023 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 2024 end on July 2, 2023, October 1, 2023, December 31, 2023, and March 31, 2024, respectively. The four quarters in fiscal 2023 ended on July 3, 2022, October 2, 2022, January 1, 2023, and March 31, 2023, 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, and the Company’s estimates and assumptions may evolve as conditions change. Actual results could differ 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 from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition The Company’s revenues by reportable segments are presented in Note 16 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. 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 2024 and 2023 amounted to $68,812 and $56,202, respectively. Revenues recognized over time for the six months of fiscal 2024 and 2023 amounted to $127,466 and $113,206, respectively. On October 1, 2023, the aggregate transaction price allocated to unsatisfied (or partially unsatisfied) performance obligations was approximately $121,895, of which, the Company estimates that approximately $89,876 will be recognized as revenue in fiscal 2024, $31,657 in fiscal 2025, and $315 in fiscal 2026, $23 in fiscal 2027, and $24 thereafter. 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 1, 2023, the current and non-current portion of contract liabilities were $23,501 and $955, respectively. As of March 31, 2023, the current and non-current portion of contract liabilities were $34,594 and $1,437, respectively. Revenues recognized during the second quarter of fiscal 2024 and 2023 that were included in the contract liability at the beginning of the quarter, amounted to $6,737 and $5,832, respectively. Revenues recognized during the six months of fiscal 2024 and 2023 that were included in the contract liability at the beginning of the year, amounted to $14,113 and $6,877, respectively. Amounts representing work completed and not billed to customers represent contract assets and were $54,825 and $48,616 as of October 1, 2023 and March 31, 2023, 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 1, 2023, the right of return asset related to the value of inventory anticipated to be returned from customers was $4,647 and refund liability representing amounts estimated to be refunded to customers was $7,748.

Receivables [Abstract]
Accounts Receivable	. Accounts Receivable October 1, 2023 March 31, 2023 Accounts receivable $ 546,189 $ 646,592 Allowance for doubtful accounts 9,688 8,775 Accounts receivable, net $ 536,501 $ 637,817 During the third quarter of 2023, the Company entered into a Receivables Purchase Agreement (RPA), under which the Company continuously sells its interest in designated pools of trade accounts receivables, at a discount, to a special purpose entity, which in turn sells certain of the receivables to an unaffiliated financial institution ("unaffiliated financial institution") on a monthly basis. The Company may sell certain US-originated accounts receivable balances up to a maximum amount of $150,000. In return for these sales, the Company receives a cash payment equal to the face value of the receivables and is charged a fee of Secured Overnight Financing Rate (“SOFR”) plus 85 basis points against the sold receivable balance. The program is conducted through EnerSys Finance LLC ("EnerSys Finance"), an entity structured to be bankruptcy remote, and matures in December 2025. The Company is deemed the primary beneficiary of EnerSys Finance as the Company has both the power to direct the activities that most significantly impact the entity’s economic performance and the obligation to absorb losses or the right to receive the benefits that could potentially be significant to the entity from the transfer of the trade accounts receivables into the special purpose entity. Accordingly, EnerSys Finance is included in the Company’s Consolidated Condensed Financial Statements. Receivables sold to unaffiliated financial institutions under the program are excluded from “Accounts receivable, net” on the Company’s Consolidated Condensed Balance Sheets, and cash receipts are reflected as cash provided by operating activities on the Consolidated Condensed Statements of Cash Flows. The purchase price is received in cash when the receivables are sold, and fees charged relating to this balance are recorded to other (income) expense. Certain unsold receivables held by EnerSys Finance serve as collateral to unaffiliated financial institutions. These unsold receivables are included in “Accounts receivable, net” in the Company’s Consolidated Condensed Balance Sheets. The Company continues servicing the receivables which were sold and in exchange receives a servicing fee from EnerSys Finance under the program. During the second quarter and the six months of fiscal 2024, the Company sold $174,372 and $356,763, respectively, of accounts receivables for approximately $174,372 and $356,763, respectively, in proceeds to an unaffiliated financial institution, of which $179,132 and $362,484, respectively, were collected as of October 1, 2023. Total collateralized accounts receivables of approximately $219,657 were held by EnerSys Finance at October 1, 2023.

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 1, 2023 and March 31, 2023, and the basis for that measurement: Total Fair Value Measurement October 1, 2023 Quoted Price in Significant Significant Lead forward contracts $ 52 $ — $ 52 $ — Foreign currency forward contracts (1,010) — (1,010) — Interest Rate Swaps 4,671 — 4,671 — Net investment hedges (14,960) — (14,960) — Total derivatives $ (11,247) $ — $ (11,247) $ — Total Fair Value Measurement March 31, 2023 Quoted Price in Significant Significant Lead forward contracts $ (89) $ — $ (89) $ — Foreign currency forward contracts 923 — 923 — Interest Rate Swaps (1,162) — (1,162) — Net investment hedges (15,760) — (15,760) — Total derivatives $ (16,088) $ — $ (16,088) $ — 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 2023 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. The fair value of interest rate swap agreements are based on observable prices as quoted for receiving the variable one month term SOFR and paying fixed interest rates and, therefore, were classified as Level 2. 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 Third Amended Credit Facility (as defined in Note 11), 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 fair value of the 2027 Notes represents the trading values based upon quoted market prices and are classified as Level 2. The 2027 Notes were trading at approximately 91% and 92% of face value on October 1, 2023 and March 31, 2023, respectively. The carrying amounts and estimated fair values of the Company’s derivatives and Senior Notes at October 1, 2023 and March 31, 2023 were as follows: October 1, 2023 March 31, 2023 Carrying Fair Value Carrying Fair Value Financial assets: Derivatives (1) $ — $ — $ — $ — Financial liabilities: Senior Notes (2) $ 300,000 $ 272,610 $ 300,000 $ 276,000 Derivatives (1) $ (11,247) $ (11,247) $ (16,088) $ (16,088) (1) Represents lead, foreign currency forward contracts, interest rate swaps, and net investment hedges (see Note 6 for asset and liability positions of the lead, foreign currency forward contracts, interest rate swaps, and net investment hedges at October 1, 2023 and March 31, 2023). (2) The fair value amount of the Senior Notes at October 1, 2023 and March 31, 2023 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 Financial Instrument

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 1, 2023 and March 31, 2023, the Company has hedged the price to purchase approximately 59.0 million pounds and 50.0 million pounds of lead, respectively, for a total purchase price of $58,166 and $47,921, 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 1, 2023 and March 31, 2023, the Company had entered into a total of $43,756 and $45,823, respectively, of such contracts. Interest Rate Swap Agreements The Company is exposed to changes in variable interest rates on borrowings under our credit agreement. On a selective basis, from time to time, it enters into interest rate swap agreements to reduce the negative impact that increases in interest rates could have on our outstanding variable rate debt. At October 1, 2023 and March 31, 2023 such agreements effectively convert $200,000 of our variable-rate debt to a fixed-rate basis, utilizing the one-month term SOFR, as a floating rate reference. Fluctuations in SOFR and fixed rates affect both our net financial investment position and the amount of cash to be paid or received by us under these agreements. 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 December 23, 2021, the Company entered into cross currency fixed interest rate swap agreements, with aggregate notional amounts of $300,000, to hedge its net investments in foreign operations against future volatility in the exchange rates between U.S. dollars and euros. 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 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 $7,239 of pretax (gain) 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 1, 2023 and March 31, 2023, the notional amount of these contracts was $64,301 and $102,558, 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 2024 and 2023 was based on the estimated effective tax rates applicable for the full years ending March 31, 2024 and March 31, 2023, 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, changes in tax laws and the amount of the Company's consolidated earnings before taxes. On August 16, 2022, the Inflation Reduction Act of 2022 (“IRA”) was enacted. The IRA includes multiple incentives to promote clean energy, and energy storage manufacturing among other provisions with tax credits available from 2023 to 2032, subject to phase down beginning in 2030. In particular the IRA creates a refundable tax credit, pursuant to Section 45X of the Internal Revenue Code (“IRC”), for battery cells and battery modules manufactured or assembled in the United States and sold to third parties. In the second quarter and six months of fiscal 2024, the IRA impact resulted in a reduction of our costs of goods sold and income tax payable of $21,816 and $41,234, respectively. There is a possibility that additional clarification guidance is issued with respect to the Section 45X credit qualifications. Amounts recognized in the Consolidated Condensed Financial Statements are based on Management's judgement and best estimate utilizing the most current guidance. The Company will continue to evaluate the effects of IRA as more guidance is issued and the relevant implications to our Consolidated Condensed Financial Statements. Actual results could differ from management’s current estimate . The consolidated effective income tax rates for the second quarter of fiscal 2024 and 2023 were 11.2% and 14.4% and for the six months of fiscal 2024 and 2023 were 10.2% and 15.0%, respectively. The rate decrease in the second quarter and six months of fiscal 2024 compared to the prior year periods are primarily due to the impact of the IRA offset by the mix of earnings among tax jurisdictions. Foreign income as a percentage of worldwide income is estimated to be 56% for fiscal 2024 compared to 83% for fiscal 2023. T his reduction is primarily due to the IRA Impact on domestic earnings .

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 2023 Annual Report.

A substantial portion of these plans are complete with an estimated $4,959 remaining to be incurred by the end of fiscal 2024, mainly related to new plans started in fiscal 2024. Restructuring and exit charges for the second quarter of fiscal 2024 by reportable segments are as follows: Quarter ended October 1, 2023 Energy Systems Motive Power Specialty Total Restructuring charges $ 2,226 $ 847 $ 34 $ 3,107 Exit charges — 2,632 1,495 4,127 Restructuring and other exit charges $ 2,226 $ 3,479 $ 1,529 $ 7,234 Six months ended October 1, 2023 Energy Systems Motive Power Specialty Total Restructuring charges $ 2,714 $ 847 $ 34 $ 3,595 Exit charges — 4,191 5,757 9,948 Restructuring and other exit charges $ 2,714 $ 5,038 $ 5,791 $ 13,543 A roll-forward of the restructuring reserve, excluding exit charges, is as follows: Balance as of March 31, 2023 $ 445 Accrued 3,595 Costs incurred (1,490) Foreign currency impact (3) Balance as of October 1, 2023 $ 2,547 Exit Charges Fiscal 2024 Program Renewables On November 8, 2023, the Company's Board of Directors approved a plan to stop production and operations of residential renewable energy products, which include our OutBack and Mojave brands. Management determined that residential renewable energy products no longer fit with the company’s core strategy and resources will be better allocated toward commercial energy solutions for enterprise customers. The Company currently estimates that the charges for these actions will amount to approximately $15,000 to $25,000 relating to non-cash charges including inventory and an indefinite-lived intangible asset write-offs and approximately $1,000 in cash charges including employee severance and retention payments. Fiscal 2023 Programs Sylmar In November 2022, the Company committed to a plan to close its facility in Sylmar, California, which manufactures specialty lithium batteries for aerospace and medical applications. Management determined to close the site upon the expiration of its lease on the property and to redirect production through consolidation into existing locations. The Company currently estimates total charges in the exit to amount to $10,957. Cash charges are estimated to total $7,155 primarily relating to severance and other costs to leave the site. Non-cash charges are estimated to be $3,802 relating to fixed assets, inventory, and contract assets. The plan is expected to be completed in fiscal 2024. During fiscal 2023, the Company recorded cash charges of $1,682 related primarily related to severance costs and non-cash charges totaling $417 primarily relating to contract assets. During the six months of fiscal 2024, the Company recorded cash charges of $5,512 primarily related to severance costs, relocation expenses, and manufacturing variances and non-cash charges totaling $245. The Company also recorded a non-cash write off relating to inventories of $3,098, which was reported in cost of goods sold. Ooltewah On June 29, 2022, the Company committed to a plan to close its facility in Ooltewah, Tennessee, which produced 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 majority of these charges are expected to be recorded by the end of calendar 2023. During fiscal 2023, the Company recorded cash charges relating to severance and manufacturing variances of $2,735 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 $1,613, which was reported in cost of goods sold. During the six months of fiscal 2024, the Company recorded cash charges relating to site clean up and decommissioning equipment of $2,176. Fiscal 2021 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 produced 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 January 1, 2023. 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 fiscal 2023, the Company recorded cash charges of $2,207 relating to primarily to site cleanup and $562 of non-cash charges relating to accelerated depreciation of fixed assets.

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. 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. During the fourth quarter of fiscal 2023, the Company drew $300,000 in the form of the Third Amended Term Loan. Additionally, the Company derecognized the capitalized deferred asset and recognized the $1,096 as deferred financing costs. During the fourth quarter of fiscal 2023, the Company entered into a fourth amendment to the 2017 Credit Facility (as amended, the “Fourth Amended Credit Facility”). The Fourth Amended Credit Facility replaces the London Interbank Offered Rate (“LIBOR”) with the Secured Overnight Financing Rate (“SOFR”) in the calculation of interest for both the Second Amended Revolver and the Second Amended Term Loan. Subsequent to the fourth amendment, the quarterly installments payable on the Second Amended Term Loan are $2,606 beginning December 31, 2022, $3,909 beginning December 31, 2024 and $5,211 beginning December 31, 2025 with a final payment of $156,345 on September 30, 2026. The Fourth 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. 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 SOFR or Canadian Dollar Offered Rate (“CDOR”) plus (i) Term SOFR plus between 1.125% and 2.25% (currently 1.25% and based on the Company's consolidated net leverage ratio) or (ii) the U.S. Dollar Base Rate (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 quarterly installments payable on the Third Amended Term Loan were $3,750 beginning June 30, 2023, $5,625 beginning December 31, 2024 and $7,500 beginning December 31, 2025 with a final payment of $232,500 on September 30, 2026. The Third Amended Term Loan bears interest, at the Company's option, at a rate per annum equal to either (i) SOFR plus 10 basis points plus (i) Term SOFR plus between 1.375% and 2.50% (currently 1.50% and based on the Company's consolidated net leverage ratio) 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 were drawn on March 13, 2023, the Company paid a commitment fee of 0.175% to 0.35% at a rate per annum on the unused portion. Obligations under the Fourth 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 Fourth 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 Fourth 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 Fourth 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 1, 2023, the Company had $165,000 outstanding under the Second Amended Revolver, $198,038 under the Second Amended Term Loan, and $292,500 outstanding under the Third Amended Term Loan.

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 1, 2023 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2024. The Consolidated Condensed Balance Sheet at March 31, 2023 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 2023 Annual Report on Form 10-K (SEC File No. 001-32253), which was filed on May 25, 2023 (the “2023 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 2024 end on July 2, 2023, October 1, 2023, December 31, 2023, and March 31, 2024, respectively. The four quarters in fiscal 2023 ended on July 3, 2022, October 2, 2022, January 1, 2023, and March 31, 2023, 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, and the Company’s estimates and assumptions may evolve as conditions change. Actual results could differ 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.
