Abstract : The report covers the cycle life test of the evaluation program of secondary spacecraft cells, through 14 December 1972. The acceptance tests and general performance tests of the evaluation program were reported earlier where applicable. The purpose of the acceptance tests is to insure that all cells put into the life cycle program meet the specifications outlined in the respective purchase contracts. A sample number of cells of each type (usually five) are subjected to the general performance tests to determine the limit of their actual capabilities. The evaluation program gathers statistical information concerning cell performance characteristics and limitations which is used by spacecraft power systems planners, designers, and integration teams.
