Abstract
A golf cart, powered by a plurality of electrolytic, lead-acid batteries has an on-board battery water replenishing system. Each battery includes a manifold that feeds water to each battery cell and is capable of transmitting out of the manifold gas generated during recharging. The watering system includes a water storage tank positioned above the batteries, with inlet and outlet tubing connecting each battery manifold to the tank in a separate, parallel circuit. The outlet tubing has a critical size of internal diameter (ID) to assure the formation of gas generated during recharging as bubbles in the outlet tubing so as to trap liquid between bubbles and to cause flow of liquid back to the tank. A one-way flow control valve is positioned in the inlet tubing to assure unidirectional flow. The outlet tubing ID must be less than ⅜ inch, with a preferred size being ¼ inch.
