Exhibit 10.2

SEPARATION AGREEMENT AND GENERAL RELEASE

THIS SEPARATION AGREEMENT AND GENERAL RELEASE (“Agreement”) is made and entered into by and between Edward R. Tetreault (“Tetreault”) and Exide Technologies, a Delaware Corporation, with offices at 13000 Deerfield Parkway, Building 200, Milton, Georgia 30004 (“Exide”).

WHEREAS, on October 4, 2011, Exide Technologies notified Tetreault that his employment was terminated effective October 4, 2011. (“Termination Date”).

WHEREAS, Exide and Tetreault desire to effect a final settlement of any and all issues raised by Tetreault’s hiring by, employment with, and separation from Exide.

NOW, THEREFORE, in consideration of the mutual promises herein contained and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, Exide and Tetreault agree and covenant as follows:

1. Payments and Benefits. On or after the Effective Date of this Agreement, as defined herein, assuming Tetreault continues to comply with the provisions of this Agreement, Exide will provide Tetreault with the following benefits:

(a) Exide will pay Tetreault for 7 days of accrued unused vacation time, less normal deductions for federal and state taxes and other withholdings. In addition, Exide will pay Tetreault an amount equal to two weeks notice pay. The notice pay and payout for accrued unused vacation time will total $23,456.73, less normal deductions for federal and state taxes and other withholdings, and will be paid to Tetreault upon the Effective Date of this Agreement, as defined herein.

(b) Exide will pay Tetreault the amount of $14,948.00 semi-monthly for 6 months (“Separation Payments”), subject to normal deductions for federal and state taxes and other withholdings. The Separation Payments shall not be subject to reduction or mitigation should Tetreault find alternative employment during such six month period. The Separation Payments will be paid to Tetreault in installments, consistent with Exide’s regular payroll schedule and direct deposited into Tetreault’s payroll deposit account.

(c) Tetreault’s medical, vision and dental benefits will continue in a manner substantially the same as those benefits provided immediately prior to Tetreault’s termination and at substantially the same cost to Tetreault (but subject to increases applied to active salaried employees) until the end of the month in which the final Separation Payment is made. All other benefits ceased on the Termination Date. During the period described above, the difference between the cost for benefit continuation coverage that Tetreault would be required to pay under COBRA and the amount Tetreault is required to pay for continuing coverage under this Agreement will be considered imputed income to Tetreault. Tetreault will be responsible for payment of income tax as a result of such imputed income. Following the period of medical, vision and dental benefit continuation specified in this Paragraph, Tetreault may, under certain circumstances, elect to continue participating in Exide’s medical and dental plans for a limited period of time by electing COBRA continuing coverage. Additional information about COBRA continuation may be obtained by contacting Ms. Karen Smith, Manager Employee Benefits, Exide Technologies, 13000 Deerfield Parkway, Bldg. 200, Milton, GA 30004.

(d) Exide will permit Tetreault to keep the iPad, cellular telephone, and printer that Exide gave to Tetreault for his use during his employment with Exide; provided, however, that Tetreault immediately presents the iPad to Exide for review and deletion of any company information stored on the iPad.

(e) Exide will reimburse Tetreault $643.68 for outstanding business expenses incurred by Tetreault up through October 4, 2011. Further, Exide will reimburse Tetreault $1213.53 for outstanding relocation expenses. Also, Exide will reimburse Tetreault for his August, September, and October natural gas expenses, October electricity and water expenses and any other October relocation expenses, provided that Tetreault provides adequate and appropriate documentation of the expenses. Tetreault agrees that he has no outstanding business or relocation expenses besides those listed in this Paragraph.

The above payments and benefits shall be the only payments or awards to which Tetreault shall be entitled and shall be in lieu of and discharge any and all obligations of Exide to Tetreault with respect to his employment with or separation from Exide, including, but not limited to, compensation, lost wages, vacation pay, sick days, and personal days, lost benefits, bonuses, commissions, severance payments, short and long term incentive plan payments or awards, inducements, relocation payments, business expenses, income protection payments, pain and suffering, or any other expectation of remuneration or benefit on the part of Tetreault. Other than the obligations specifically set forth in this paragraph 1, Exide shall have no other obligations to Tetreault. Tetreault understands and agrees that the payments and benefits described herein are greater than that required by Exide’s policies, procedures, or by agreement.

2. Non-Admission of Liability. This Agreement shall not in any way be construed as an admission by Exide as to any liability or that Tetreault has any rights whatsoever against Exide, except as provided in this Agreement, including its Exhibits. Further, Exide specifically disclaims any liability to or wrongful acts against Tetreault or any other person. Similarly, this Agreement shall not in any way be construed as an admission by Tetreault as to any liability or that Exide has any rights whatsoever against Tetreault, except as provided in this Agreement, including its Exhibits. Further, Tetreault specifically disclaims any liability to or wrongful acts against Exide or any other person.

3. Complete Release by Tetreault. As a material inducement to Exide to enter into this Agreement, Tetreault hereby absolutely, unconditionally, and irrevocably releases, acquits, discharges, and waives forever and for all purposes and all respects Exide and each of Exide’s past, present and future parents, affiliates, subsidiaries, divisions, employee benefit plans and trusts, owners, predecessors, successors, assigns, and their agents, managers, directors, officers, partners, shareholders, insurers, and employees, including, but not limited to, their representatives, consultants, investigators, attorneys, and all persons acting by, through, under or in concert with any of them (collectively “Releasees”) from any and all complaints, promises, agreements, actions or causes of action, damages (including attorneys’ fees and costs actually incurred), expenses, compensation, penalties, liabilities, and obligations of any kind or nature whatsoever, known or unknown, direct or consequential, foreseen or unforeseen, including, but

2

not limited to, rights arising out of alleged violations of any Exide plans, benefits, policies, practices, or programs, any contracts or commitments, express or implied, or any covenant of good faith and fair dealing, express or implied, or any tort, or any legal restrictions on Exide’s right to terminate employees, including, but not limited to, wrongful termination, or any federal, state, or other governmental statute, regulation, or ordinance, including, but not limited to, the Age Discrimination in Employment Act, 29 U.S.C. §§ 621-634 (“Claim” or “Claims”), which Tetreault now has, may have, or may claim to have, or which he at any time heretofore had or claimed to have, against Exide up through and including the Effective Date of this Agreement; provided, however, that this release does not cover any claim that cannot be released by law. The listing of specific types of claims as set forth above is not intended to limit in any way the general and comprehensive scope of this release from Tetreault to Exide.

4. No Other Claims. Tetreault represents that he has not filed any complaints or lawsuits against Exide with any state or federal governmental agency or with any court, and that he will not do so at any time hereafter for any event that occurred as of the execution date of the Agreement, and that any complaints or lawsuits filed prior to execution of this Agreement will be withdrawn by him immediately after this Agreement becomes effective.

5. Termination; No Reemployment. Tetreault agrees that his active employment terminated on the Termination Date. Tetreault agrees that he will not seek reemployment by the Releasees or reapply for any position with the Releasees at any time. A breach of this paragraph by Tetreault will constitute a basis for refusal to employ Tetreault or to terminate him if already employed.

6. Cessation of Authority. Tetreault understands and agrees that effective October 4, 2011, he was no longer authorized to incur any expenses, obligations, or liabilities on behalf of Exide.

7. Return of Company Materials and Property. Tetreault understands and agrees that, to the extent he has not already done so, and except as provided in Paragraph 1(d) of this Agreement, he will turn over to Exide all documents, equipment, including, but not limited to, Exide’s computer and peripherals issued to Tetreault, keys, user IDs and passwords, parking pass, files, notes, records, credit cards, and other physical or personal property that Tetreault received from Exide and that are the property of Exide.

8. Non-Disparagement. Tetreault represents and agrees that he will not, directly or indirectly, publish, utter, broadcast, or otherwise communicate, directly or indirectly, any information, misinformation, comments, opinions, remarks, articles, letters, or any other form of communication, whether written or oral, regardless of its believed truth, to any person or entity (including, without limitation, current or former Exide employees, Tetreault’s potential and/or subsequent employers and coworkers, and Exide’s suppliers, vendors, and competitors) that are materially adverse to, reflect unfavorably upon, or tend to disparage any or all of the Releasees or the business, products, prospects, or financial condition of any or all of the Releasees, except as otherwise required by court order or subpoena issued by a court or governmental agency.

9. Future Cooperation. As a material inducement to Exide to enter into this Agreement, Tetreault agrees to cooperate with Releasees in any pending or future matters, including, but not limited to, any litigation, investigation, or other dispute in which Tetreault, by virtue of Tetreault’s prior employment with Exide, has relevant knowledge or information.
