Abstract
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.
