Space cell test program, life cycle tests. Monthly progress report
Under normal operation, complete data were recorded every 32 cycles on the 90-minute and 3 hour packs. On the 24-hour packs, complete data were taken every eight cycles. Before cycling, each pack was given a capacity test at its respective cycling temperature. This consisted of a c/10 charge for 16 hours followed by a c/2 discharge to 1.0 volt per cell average. After 88 days of cycling, each pack was discharged immediately after the end of the regular cycle period, at the c/2 rate to 1.0 volt per cell average. The pack was then recharged at the c/10 rate for 16 hours and discharged at the c/2 rate to 1.0 volt per cell average. The pack was again recharged at the c/10 rate for 48 hours with voltage being limited to the cycle limits.
