Abstract
A group of electrically interconnected energy storage cells, such as nickel-hydrogen energy storage cells, is pressure balanced and its precharge reset by discharging the energy storage cells of the group to a substantially fully discharged state, venting all of the energy storage cells of the group to the same reduced internal hydrogen pressure, and thereafter discontinuing the venting. The venting occurs without recharging the energy storage cells, and after venting is complete the energy storage cells of the group are recharged.
