Abstract
A multicell storage battery, especially of the nickel/hydride type, is provided with pressure safeties for protection against high internal pressures. The pressure safeties respond at a preassigned critical pressure, causing mechanical changes in shape or through destruction which can be optically or electrically monitored. For example, a hinged lid is caused to swing up responsive to a rupture disk, interrupting a light beam. Alternatively, a rupture disk is coated with a conducting enamel and is connected by lead wires to form an electrical circuit which is interrupted responsive to damage of the enamel layer (e.g., responsive to bursting of the membrane).
