A safety electrical disconnect is incorporated within the battery terminal to break the circuit upon excessive internal pressure build-up due to extended discharge or over charge, A burst diaphragm ruptured by excessive pressure forces a ball through a normally restraining split ring to thereby interrupt the electrical circuit continuity. The ball, upper seat and split ring can be designed to either prevent further escape for internal gas or provide for controlled venting. The burst diaphragm may be replaced by another pressure sensing device such as a pop-off valve. For high current capability, the ball and ring may be replaced by a suitable arrangement such as a sliding cylindrical connector. Author
