Operations Desert Shield and Desert Storm the reality that it is not enough for a battery to be safe at high temperature. The military also requires them to operate reliably at high temperature.This paper first discusses some of the problems encountered with aircraft batteries during Operations Desert Shield and Desert Storm. It then describes testing vented Ni-Cd batteries at temperatures as high as 190°F that simulated flying multiple sorties with the engine start battery charged from the aircraft bus. This paper then presents the test results that indicate current airborne charge limit parameters can be increased and allow military aircraft operate in greater temperature extremes. This paper concludes with recommendations on further improvements to low maintenance Ni-Cd batteries that will further enhance the operational flexibility of this robust battery design.
