The simulation of a worst-case situation for the nickel hydrogen battery during the shuttle launch of INTELSAT VI has led to some interesting and unexpected results, such as: 1) a significantly higher self-discharge rate during the first eight hours of open circuit stands, 2) a pressure-depleting self discharge which does not result in capacity loss, and 3) a pressure decay and capacity loss dependent on the overcharge rate. Based on these observations, it is postulated that more than one-self-discharge reaction occurs, and that under some circumstances pressure decay cannot directly be related to capacity loss.
