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.

I claim: 1. A single point watering system for use with a lead-acid battery having a plurality of battery cell access ports, the system comprising: a plurality of refill valves; a manifold having (i) an elongated water feed tube with at least one external port and a plurality of outlets positioned at intermediate locations along its length 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; said manifold also having a plurality of cylindrical enclosures each configured to receive one of said refill valves such that each refill valve inlet is in sealed relationship with one of the feed tube outlets, and said at least one gas discharge passageway in fluid communication with adjacent enclosures; and said manifold being removably and sealably mountable to said battery so that each refill valve is in fluid communication with one of the battery cell access ports. 2. The single point watering system of claim 1 wherein said feed tube has opposing ends with one external port located at one end and two external ports located intermediate said ends. 3. The single point watering system of claim 1 wherein each of said refill valves includes a valve body and an acuator, the valve body of each valve being housed within one of the manifold enclosures and the acuator of each valve extending from the manifold into one of said battery cell access ports. 4. The single point watering system of claim 1 wherein said water feed tube has an external port at each of its ends and two external ports intermediate its ends. 5. The single point watering system of claim 1 wherein two manifolds are sealably mounted to said battery and are connected so that the feed tube of each manifold is in fluid communication with the other. 6. The single point watering system of claim 1 wherein said manifold comprises a base and a cover which are sealably joined and cooperate to form said enclosures for each valve body, and the gas discharge passageway is located between adjacent enclosures. 7. The single point watering system of claim 6 wherein the base includes a baffle positioned between adjacent enclosures to substantially isolate the water and electrolyte for one cell from that of an adjacent cell. 8. The single point watering system of claim 7 wherein said manifold base includes sloping surfaces to direct water and electrolyte from the gas discharge passageway into the battery cells. 9. The single point watering system of claim 1 wherein said lead-acid battery is a marine deep cycle battery. 10. The single point watering system of claim 1 wherein the battery has threaded access ports and said system further comprises an externally threaded adaptor which mates with the battery access port and cooperates with said manifold to removably and sealably mount the manifold to the battery. 11. The single point watering system of claim 1 wherein said manifold houses three refill valves.
