What is Pro-Fill?

The Pro-Fill Battery Watering System is the only system on the market specifically designed to water deep cycle (i.e. golf car style) batteries. The system consists of automatic shut-off valves, interconnected with tubing, that replace the existing vent caps. A quick coupling allows the system to be connected to a water supply. Once connected, water flows into each cell until it reaches the correct level. A flow indicator built into the water supply tells the operator when filling has been completed. The entire process takes less than one minute.
