A User Friendly Solution for Watering Your Batteries All battery watering systems are equipped with self-regulating valves that are assembled with clear tubing. Pairing the quick-connects allows water to flow through the tubing and into the valves, filling each cell with the precise amount of water. Water your batteries in a matter of seconds! The Gravity Tank The Gravity Tank was designed with golf cart users in mind. The 2.5 gallon tank allows for a steady flow of water from a single connection. Place the tank at least 3 feet (or higher) above the batteries, hook it up to the battery watering system, and let gravity do its thing! Once the flow indicator stops spinning, the watering cycle has completed. Disconnect the connectors and you’re all done! The Manual Pump Simply place the open end in a jug of distilled water and attach the quick-connects to the watering system. Squeeze the bulb on the manual pump to begin the water flow.
