BLUE BELL, Pa., December 13, 2010 - C&D Technologies, Inc. announced today that it has adjourned a special meeting of stockholders, which had been called in order to approve the exchange offers for its outstanding 5.25% Convertible Senior Notes due 2025 and 5.50% Convertible Senior Notes due 2026 in exchange for shares of the Company’s common stock and certain amendments to the Company’s certificate of incorporation in connection with the exchange offers until 3:00 PM EST on Monday, December 20, 2010 at the corporate offices of C&D located at 1400 Union Meeting Road, Blue Bell, Pennsylvania.

Dr Jeffrey Graves, President and Chief Executive Officer said “the special meeting previously scheduled in connection with our financial restructuring was adjourned today to provide additional time to secure a quorum for the meeting.
