Forty-two, 50 A h nickel-cadmium cells were delivered to the Goddard Space Flight Center (GSFC) by General Electric (GE) in February, 1985 for the purpose of evaluating and qualifying a new, nonwoven nylon separator material, Pellon 2536, and the new GE positive plate passivation process. Testing began in May, 1985 at the Naval Weapons Support Center (NWSC) at Crane, Indiana with GSFC standard initial evaluation tests. Life cycling in both low earth orbit (LEO) and geosynchronous orbit (GEO) began in July, 1985 with approximately 6500 LEO cycles and three GEO eclipse seasons complete at this writing. After early problems in maintaining test pack temperature control, all packs were performing well but were exhibiting higher than normal charge voltage characteristics.
