Three life tests have been conducted on the INTELSAT V nickel-cadmium battery assembly. Each test was conducted at different cycling rates so that performance trends could be identified prior to the equivalent point achieved on the flying spacecraft batteries. The results indicated there is no significant degradation mode which is out of the ordinary. One battery was exposed to 20 seasons of cycling over one year's time while a second battery has 30 seasons of cycling over 6 year's time. A real-time test now has 11 seasons of simulation achieved. The laboratory data supports the actual flight data which is observed from five spacecraft now operating with this battery system. No significant performance anomalies or degradation has been reported from the spacecraft that are in orbit.
