Automatic shutoff: The Watering Gun fills cells to precisely the correct level. The shutoff is so positive you can actually feel it.
Safe: It keeps eyes and face away from battery hazards, and reduces backache from bending over batteries. It is insulated to prevent sparking on connectors.
Reliable: The shutoff mechanism has been tested to 1 million cycles and proven in hundreds of thousands of tough applications worldwide. Powered by the water itself, it has no solenoids, no electronics and no wiring.
Fast but gentle: The flow rate is 1.7 gallons/minute (6.4 liters/minute), which is fast enough for the largest cells. Yet the flow is gentle enough to fill a coffee mug.
Easy Installation: Attach the Battery Watering Gun to any standard garden hose, our HydroFill Watering Cart or our Deionizer System and you have a fully operating battery filling system.
