A rechargeable electrochemical cell is provided having a pressure-responsive apparatus for determining a charge termination point. In particular, a reversible pressure-responsive switch may be disposed in a rechargeable cell. A sensor determines when the switch has reacted in a predetermined manner, thus indicating that the internal pressure within the cell has reached a predetermined threshold. The sensor is part of sensing circuitry that is linked to a charger having automatic charging modes depending on the status of the sensing circuit.
