Performance Status of Super NiCd™ Batteries

Since the late 1980s Super NiCd™ Batteries have been used by Hughes Space and Communications, Co. (HSC), NASA, TRW, Lockheed Martin Space and Missiles Group, and Johns Hopkins University Applied Physics Laboratory. In early flight programs with the technology, some capacity losses on long-term storage were experienced, but recently batteries with storage up to five years prior to launch are yielding within 2-3% of prestrorage capacity and are demonstrating managable performance in orbit.
