What is Pro-Fill RV?
Pro-FIll RV on-board watering system for 6V batteries simplifies the routine chore of re-filling your RV 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. Fits all standard 6V batteries.
What can Pro-Fill RV do for you?
More Convenient: Fill up to six batteries in seconds from a single fill point. Several batteries can be connected and filled at the same time.
Safer: Eliminates need to routinely remove vent covers which could expose you to battery acid.
More Reliable: Over-filling and under-filling batteries both result in lost capacity. Pro-Fill RV fills to the correct level every time, giving you optimal battery life.
Easy to Use: Installs in minutes, no tools required. Use with any distilled water container.
