Abstract
The present invention is directed to a single point watering system for use with a lead-acid battery having a plurality of battery cell access ports. The system comprises a plurality of refill valves and a plurality of refill valves and a manifold having (i) a water feed tube with at least one external port and a plurality of outlets each communicating with one of the plurality of refill valves, and (ii) at least one passageway housing a flame arrestor to permit the discharge of gases from the battery cells to the surrounding environment only through the flame arrestor. The manifold is removably and sealably mountable to the battery so that each refill valve is in fluid communication with one of the battery cell access ports.
