★Pro-Fill Battery Watering System - $40 (Yuma)

Pro-FIll RV on-board watering system for 6V batteries simplifies the routine chore of re-filling your RV batteries.

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.
