A galvanic cell is described comprising a conductive container open at one end and closed at the opposite end and including in the container a positive electrode, a negative electrode and an electrolyte with the container being in electrical contact with one of the electrodes. A cover mounted over the open end of the conductive container, is secured to and electrically insulated from the conductive container and in electrical contact with the other electrode. A conductive member, comprises a central portion and a peripheral flange portion and the central portion is in electrical contact with the peripheral flange portion. The central portion is secured by electrically insulating means to the external central area of the closed end of the container with the peripheral flange portion being secured to and electrically connected to the external peripheral area of the closed end of the container thereby adapting the central portion of the conductive member as the terminal for the electrode in electrical contact with the container. The central portion will separate from the peripheral flange portion of the conductive member when the center area of the closed end of the container bulges a predetermined amount thereby electrically isolating the central portion terminal from the electrode in electrical contact with the container.
