What is a Pro-Fill RV battery watering system?
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 a battery watering system 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.
