ABSTRACT:
A venting plug for a wet, lead-acid storage battery, a battery containing the same, a method of molding the venting plug body, and a mold for molding the venting plug body are disclosed. The sealing surfaces of the venting plug do not include a mold parting line along which acid from inside of the battery could seep between the seal and sealing surfaces. The venting plug body, however, includes a coupling structure that includes a mold parting line. The sealing surfaces of the venting plug body are molded by a single plate such that no mold parting line results along the sealing surfaces, while the coupling structure is molded by plurality of mold components such that a mold parting line results in the vicinity of the coupling structure.
