ABSTRACT:
A container for a remotely-vented lead-acid storage battery includes a multi-compartment base containing individual cells of the battery and an overlying cover in vapor-sealed engagement with the base. A gas collection manifold positioned within a recess in the bottom surface of the cover includes a plurality of interconnected expansion chambers which communicate with respective ones of the battery cell compartments, and a discharge port exterior to the battery container. Battery gas collected within the expansion chambers is conveyed within the manifold to the discharge port, thereby avoiding the need for additional gas collection elements external to the cover and the attendant possibility of leakage of battery gas in the vicinity of the battery.
