A storage battery, particularly adapted for automotive applications, includes unique cover, venting and terminal constructions which, in their various embodiments, can accommodate virtually any automobile cable arrangement. Each of the several embodiments utilizes an identical container, electrode construction, intercell assembly and venting arrangement. Various types of exterior battery terminals, accommodating both conventional pressure clamps and threaded connectors, are connected to the battery electrodes through an intermediate primary cover. An outer secondary cover encloses the entire top of the battery, except for direct access to the exterior terminals, and the venting assembly is totally enclosed between the primary and secondary covers.

Storage battery construction

A composite battery plate grid comprising a plastic support molded to engage portions of a metallic conductive member. Using first and second mold halves, the conductive member is cast in a first pattern in the first and/or second mold halves. The plastic support is then injection molded in a second pattern in the first and/or second mold halves. In the alternative, after casting the conductive member in the first pattern, the second mold half is replaced by a third mold half with the conductive member remaining in the first mold half, and the plastic support is injection molded in a second pattern in the first and/or third mold halves. In all cases, during injection molding, the plastic material is caused to flow at selected portions of the conductive member, where, upon solidifying, the plastic support engages portions of the conductive member.
