The data base for geosynchronous performance of nickel-hydrogen cells is still somewhat limited. This paper adds to the data base by presenting performance data from two operating spacecraft and one laboratory life test battery with nickel-hydrogen cells of the COMSAT/INTELSAT design. The two operating spacecraft are the U.S. Navy's Navigation Technology Satellite-2 (NTS-2) and the INTELSAT V F-6. The NTS-2 battery has been operating for 7 years (14 eclipse seasons) while the INTELSAT V battery is relatively new (1 year and two eclipse seasons). An update of the NTS-2 battery performance is presented along with the INTELSAT V operational data for the first two eclipse seasons. The laboratory test setup consists of a 10-cell nickel-hydrogen battery operated in a simulated geosynchronous environment. This battery has been operating for over 8 years (18 eclipse seasons). A cell was removed for destructive physical analysis (DPA) after 5.2 years of operation. Battery performance and cell data are presented.
