The Nickel Hydrogen batteries used aboard the Mars Global Surveyor (MGS) is described. The mission itself is briefly described. This is followed by a description of the full electric power subsystem, and the design of the MGS 20 AH cell design. Graphic presentations show characteristics of the battery's performance. In summary, even though the charge control seems to be well, the method used is not recommended, due to an unexpected increase in pressure observed in flight. The operations have been modified to further minimize overcharge, and the pressure increase is not expected to impact the mission.
