Abstract
A water by-passing, submersible, flame retardent vent plug is adapted for use in storage batteries of the type containing liquid electrolyte. The plug has inlet and outlet slots and a hollow portion providing a gas communication path. A porous flame arrester is positioned in the path. A circular raised seat is positioned in the path between the flame arrester and the outlet slots to allow water from the battery's exterior which enters the outlet slots, to exit the vent plug without entering the battery.
