Dear Mr. Wolf:

     Reference is made to the Loan and  Security  Agreement,  dated  December 7,
2005, by and among C&D Technologies,  Inc. ("Parent"), C&D Technologies (Datel),
Inc.("Datel"),  C&D Technologies  (CPS) LLC ("CPS", and together with Parent and
Datel, the "Borrowers"),  C&D Charter  Holdings,  Inc.  ("Charter"),  C&D Dynamo

Investment Holdings Inc. ("International") and Datel Holding Corporation ("Datel
Holding", and together with Charter, Dynamo, Acquisition and International,  the
"Guarantors"),  the parties  thereto  from time to time as  lenders,  whether by
execution of the Loan Agreement or an Assignment  and Acceptance  (collectively,
the  "Lenders"),  and Ableco  Finance  LLC,  as agent for the  Lenders  (in such
capacity,  the  "Agent"),  (as amended by  Amendment  No. 1 to Loan and Security
Agreement,  dated March 30, 2006,  by and among Agent,  Lenders,  Borrowers  and
Guarantors  and by the Consent,  Waiver and Amendment No. 2 to Loan and Security
Agreement, dated as of June 14, 2006, by and among Agent, Lenders, Borrowers and
Guarantors,  and as  the  same  may  hereafter  be  further  amended,  modified,
supplemented,  extended,  renewed,  restated or replaced, the "Loan Agreement").
Capitalized terms used but not defined herein have the meanings ascribed thereto
in the Loan Agreement.

     The Parent has advised the Agent that the Parent and its Subsidiaries (on a
consolidated  basis) may be unable to meet the Leverage Ratio financial covenant
as of the  last  day  of  the  calendar  month  ending  October  31,  2006  (the
"Covenant"),  as required by Section 9.17(b) of the Loan  Agreement.  The Parent
has requested that the Agent and the Lenders waive any Event of Default that may
arise as a result of non-compliance  with the Covenant (the "Event of Default").
The Agent and the  Lenders  have  agreed  that  should  such an Event of Default
occur, they waive such Event of Default through November 30, 2006.

     The agreement  contained  herein  constitutes  the entire  agreement of the
parties with respect to the subject matter hereof, and supersedes all prior oral


                                      -1-


or written communications, memoranda, proposals, negotiations, discussions, term
sheets and  commitments  with respect to the subject  matter hereof and thereof.
Except as expressly  provided herein,  no other waivers or consents are intended
or implied,  and in all other respects the Loan Agreement is hereby specifically
ratified,  restated and confirmed.  To the extent that any provision of the Loan
Agreement or any of the other agreements,  documents and instruments referred to
therein or at any time executed  and/or  delivered in connection  therewith,  is
inconsistent  with the  provisions  of this  agreement,  the  provisions of this
agreement shall control.

     Please  indicate  the Agent's  acknowledgment  and  agreement to all of the
foregoing on behalf of the Lenders by executing a copy of this  agreement in the
space provided below and returning the same to my attention.

                                              Sincerely,

                                              C&D TECHNOLOGIES, INC.
