ABSTRACT:
A battery seal is disclosed which non-destructively vents gases in response to abnormal pressure buildup, and substantially prevents moisture loss from or oxygen ingress into a battery cell. An airtight, preferably non-conductive plug is pressed downward onto a receiving member such as the top of a battery's container of active ingredients by a crimped battery jacket comprised of material of sufficiently elastic characteristics to regain its original configuration after deformation under temporary pressure.
