Abstract
A container for a maintenance-free lead-acid storage battery includes a multi-compartment base wherein individual cells of the battery are contained. An overlying cover in vapor-sealed engagement with the base includes a plurality of integrally-molded filler wells which extend from a recess in the top surface of the cover into respective cell compartments of the battery. A one-piece molded vent cover seated within the recess includes a plurality of vent plug portions which extend through the filler wells into respective ones of the cell compartments. An annular flange associated with each filler well coacts with ribs on the vent plug portions to lock the vent cover in place. Escaping battery gas is conveyed from each of the cell compartments by axially-extending recesses on the vent plug portions, which form passageways from each cell compartment, and by ribs on the underside of the vent cover which space the vent cover from the battery cover to provide an additional passageway extending to the escape gas gap through a peripheral gap formed between the vent cover and the side walls of the recess.
