A device for venting dangerous pressures within a cylindrical battery. Pressure relief is provided by special score lines in a container to give way under a pressure increase prior to the pressure rising to the level that might cause an explosive condition. To insure the score lines give before any other part, re-enforcig members are provided to re-enforce the other parts of the container.
