Your battery maintenance is faster, safer, and more reliable with the Flow-Rite Millennium EVO Single-point Battery Watering System. This watering system is engineered with automatic shut-off valves and interconnecting tubing. Simply replace the existing vent caps with your new valves, then add the quick coupler. Once connected to a water supply, the water flows until each battery cell independently reaches the correct electrolyte level. <strong>*Note: A Pressure Regulator is required to use the battery watering systems. The models shown are for use with industrial batteries with bayonet style caps only. Millennium EVO Valve lengths are 2.1”, we strongly recommend measuring the battery cell depth to ensure a proper fit. </strong>
