Abstract
A method for rejuvenating Ni-H.sub.2 battery cells suffering a voltage anomaly providing an improved cell output voltage and capacity. After the battery containing the cells suffering the voltage anomaly is removed from service, the battery is discharged. Discharging the battery reduces the hydrogen pressure within the cells, thereby increasing the rate of mass transport of free water back to the electrode stacks of the cells. The cells are then left to stand for a period sufficient to allow any free water to diffuse back to the electrode stacks. If gravity is available, the cell can simply be rotated to return the free water to the stack.
