The present invention provides for a wet, multicell, lead-acid electric storage battery comprising a venting system having vent plugs comprising an inventive sealing arrangement. Specifically, the vent plugs provide a seal to be molded onto the vent body as a permanently attached feature. The present invention consequently eliminates the need to separately manufacture and apply a gasket to a vent body, thus reducing manufacturing costs and greatly improving reliability and safety during both use and handling.

Vent plug having an integal seal

A wet, multicell, lead-acid electric storage battery is provided for. The battery comprises a container, a cover, one or more partition walls dividing the space within the container and cover into two or more cell cavities. The cover defines generally cylindrically shaped process holes associated with each cell cavity. The battery further comprises a venting system. The venting system comprises a manifold defined by the cover, the manifold having at least one opening in each process hole and at least one opening in the cover. The manifold is adapted to provide gaseous communication between the process holes and the ambient. The venting systems also comprises a venting plug associated with each process hole and adapted for insertion therein. The venting plugs have a generally cylindrical side wall, a closed upper end, an open lower end, and a central cavity. A vent aperture is located in the side wall of the venting plug and is in gaseous communication with the manifold and the venting plug central cavity. A baffle is positioned within the venting plug central cavity between the vent aperture and the lower end of the venting plug. The baffle is adapted to allow the passage of gases and to retard the passage of electrolyte from the cell cavity through the venting plug central cavity.
