FOR IMMEDIATE RELEASE

C&D Technologies Announces Completion of Reverse Stock Split

BLUE BELL, Pa., March 15, 2011 /PRNewswire-FirstCall/ — C&D Technologies, Inc. (the “Company”) announced today that it filed an amendment (the “Amendment”) to its amended and restated certificate of incorporation to decrease the number of authorized shares of the Company’s common stock, par value $.01 per share (“Common Stock”), from 600,000,000 to 25,000,000 (the “Authorized Share Reduction”). The Amendment also effected a reverse stock split of the issued and outstanding and treasury shares of Common Stock at a ratio of 1-for-35 (the “Reverse Stock Split”).

Pursuant to the Reverse Stock Split, each 35 shares of the issued and outstanding and treasury shares of Common Stock will be combined and reclassified into 1 share of Common Stock. Each stockholder otherwise entitled to receive a fractional share of Common Stock as a result of the reverse stock split will receive one full share of Common Stock in lieu of the Company issuing such fractional share or paying cash in respect thereof.

The Table below sets forth the effect of the Reverse Stock Split. The columns labeled “After Reverse Stock Split” and “After Authorized Share Reduction” in the table do not reflect the adjustments that will result from the elimination of fractional shares of our common stock in connection with the Reverse Stock Split as described above. We cannot calculate at this time the number of whole shares that will be issued in lieu of fractional shares as a result of the Reverse Stock Split.

The Company previously filed an Information Statement on Schedule 14C with the Securities and Exchange Commission describing, among other things, the Authorized Share Reduction and the Reverse Stock Split.
