Whether the RV engine battery or the house battery bank, checking electrolyte levels and adding water often involves bending, squatting and stretching to reach them. But with a Pro-FillTM Onboard Battery Watering System from Flow-Rite, routine maintenance is fast and easy. This manifold and battery fill port valve assembly enables filling all cells to the ideal level simultaneously, without contortions by the user.
The Pro-Fill single-point solution overcomes two important safety issues. First, its unique design has a built-in water barrier and flame arrestor to prevent sparks from igniting adjacent battery cell gases. Second, because it’s a sealed system, there’s no chance of acid splashing. It’s the safest method of watering batteries on the market today.
Installing the Pro-Fill Onboard Battery Watering System is a simple DIY project that doesn’t require modifying the 6-, 8- or 12-volt battery case. Each vent cap is replaced with a patented Flow-Rite shut-off valve and interconnected via the manifold assembly; multiple batteries are linked with the acid-resistant tubing. The array attaches to a water supply with a quick coupler. A flow indicator signals when filling has been completed. A video is at www.bit.ly/Pro-Fill-Install.
