Title: Vented battery cap

Patent ·
OSTI ID:6493444

A vented cap for a multiple-cell storage battery comprises a base member having a plurality of integrally molded vent plug portions adapted to fit into individual filler wells of the battery and a cover member which snaps in place over the base member to form a chamber for gas egressing from the battery. The base member includes interior walls and a plurality of integrally molded latch members which engage the rim of the cover member to secure the cover member in abutting relationship to interior walls. The interior walls are dimensioned to space the rim of the cover member from the rim of the base member, whereby a continuous vent slot is formed around the periphery of the cap, which allows battery gas to escape from the chamber with wide dispersion while inhibiting inward propagation of an externally generated flame. The latch members may be alternatively provided on the cover member so as to engage the rim of the base member. The vented cap may also be constructed in single-cell form having a single vent plug portion for insertion into a single battery filler well.
