ABSTRACT:
The negative precharge of a sealed nickel-cadmium battery cell is reduced and the uncharged negative capacity is correspondingly increased to increase the overcharge protection of the cell by overdischarging the cell at a relatively high rate and reacting hydrogen evolved in the cell during such overdischarge with a hydrogen getter which forms a hydride with the hydrogen to prevent excessive hydrogen pressure buildup in the cell.
