ABSTRACT:
The present invention comprises a battery housing suitable for holding a battery which may generate a dangerously high level of internal pressure. The housing includes a receptacle having a vent passage covered by a rupture disc, the rupture disc in turn covered by a diffuser head having a longitudinal bore therein extending from the rupture disc to a blind end, the bore being traversed by at least one lateral passage leading to the exterior of the housing. Upon reaching a predetermined internal pressure level, the rupture disc ruptures and vents the interior of the housing safely to the exterior through the lateral passage.
