A battery capable of safely venting its contents without exploding includes a casing which defines a cavity in which the electro-chemical contents of the battery is confined. A rigid partition is disposed across an opening at the end of the casing, and a relatively bendable cover is positioned so that its under surface overlies the partition. A passageway connects the cavity with the under surface of the cover, and the cover is attached to the partition at at least one location. If the internal pressure of the battery reaches a predetermined limit, as may occur if the battery is overheated, the cover is deformed away from the partition to vent the contents. However, the cover does not become detached from the partition.
