The world's best selling battery watering gun!

No battery room should be without this essential maintenance tool. Simply connect the Battery Watering Gun to a standard water hose or a Deionizer, put the gun's tip into the cell and squeeze the ergonomic handle. The mechanism will automatically shut off at precisely the correct electrolyte level. The reliable Philadelphia Scientific Battery Watering Gun speeds up battery watering, improves filling accuracy, and improves operator safety. It also saves money; compared to hand watering, our battery watering gun reduces labor costs up to $150 a year for each 18-cell battery. It's no wonder that our watering guns have been the world's most popular battery maintenance tool since 1983.

Feature and Benefits
