The purpose of this evaluation test program is to insure that all cells put into the life cycle program are of high quality by the screening of cells found to have electrolyte leakage, internal shorts, low capacity, or inability of any cell to recover its open circuit voltage above 1.150 volts on the cell short test. The five cells were purchased by Philco-Ford for the National Aeronautics and Space Administration, Goddard Space Flight Center. The cells are to be evaluated for a proposed flight battery on the Synchronous Meteorological Satellite to be launched in 1974. These cells are rated at 3.0 ampere-hours (EP Lot no. 4), contain double ceramic seals, and were fitted with pressure transducers prior to testing. Test limits specify those values in which a cell is to be terminated from a particular charge or discharge. Requirements are referred to as normal expectant values based on past performance of aerospace nickel-cadmium cells with demonstrated life characteristics.
