Add water to your batteries without ever having to touch a battery or remove a cap. Pro-Fill on-board battery watering system lets you fill up to 6 batteries from a single fill tube, using a simple hand pump.
Safer and more accurate than conventional filling, it installs in minutes without tools. Simply replace the existing battery caps with the Pro-Fill manifolds and connect together with flexible tubing. The system automatically sends water only to low cells by using automatic shut-off valves at each cell, providing electrolyte level accuracy to 1/8". Makes maintaining proper electrolyte levels in hard-to-reach batteries easy, improving battery life and performance.
Systems are reusable and can be installed on new batteries when old batteries are replaced.
