The Problem with Traditional Battery Maintenance
While the Philadelphia Scientific Battery Watering Gun is designed to make battery maintenance fast, easy, safe, and precise, the traditional screw-on/screw-off vent caps create a significant time bottleneck. For every cell, operators must waste valuable time unscrewing the cap, finding a safe place for it, filling the cell, retrieving the cap, and carefully screwing it back on. These repetitive manual steps interfere with the core efficiency goal of the watering gun, often leading to lost caps, which compromises battery health.
The Ideal Solution
Flip-Top Vent Caps are the perfect, affordable accessory designed to eliminate the frustrations of screw caps. With these caps, operators flip open the lid, insert the watering gun, fill the cell to the correct level, and then snap the lid securely shut. This seamless process eliminates the time wasted on handling screw caps and ensures the cap is never lost or dropped. Furthermore, the Flip-Tops feature huge openings that simplify routine electrolyte level checks, making them the ideal and fastest possible match for our automatic-shutoff Battery Watering Gun.
Wide Openings
The extra-wide opening enables the use of the Philadelphia Scientific Battery Watering Gun-X. This exclusive design is a new standard in the industry. The large vent opening makes it significantly easier to check electrolyte levels compared to smaller vent openings.
Built-in Acid-Splash Baffle
The vent caps’ design incorporates a baffle that prevents acid splashing from the cell. This reduces watering frequency and keeps the battery surface cleaner.
Self-Draining
The Flip-Top also avoids the problems common to screw caps, such as acid dripping onto the battery where screw caps are placed during filling. With the Flip-Top, any liquid in the lid stays contained within and drains back when the lid is snapped shut.
Rugged Construction
The acid-resistant polyolefin construction and rugged mechanical hinges are designed to withstand years of service, unlike some flexible hinge designs that can break during rough usage — especially at low temperatures.
Locks In Place
When a Flip-Top is installed on a cell, it locks in place with a positive detent action that you can feel. This prevents it from vibrating loose during the truck's operation.
