With Qwik-Fill, adding water to your batteries has never been easier or more accurate.

Qwik-Fill 12 Volt Battery Maintenance/Watering System

Why use the Qwik-Fill Battery Maintenance/Watering System?
Water level in lead acid batteries must be checked on a regular basis - a minimum of every 4 to 6 weeks; more in some climates. Improper water level will shorten battery life and result in poor performance of batteries, trolling motors, and battery chargers.

The Qwik-Fill On-board Battery Watering System provides the most convenient and accurate means of filling and maintaining proper battery water level. Hard to reach batteries are just as easy to fill as batteries on a workbench. Several batteries can be safely and simultaneously filled from a remote position without ever having to touch a battery or remove a cap. Qwik-Fill's automatic control valves ensure each cell is closed when the precise level is reached. Qwik-Fill fits all group size 24 and 27 and most 29 through 31 lead acid batteries.

Join manifold assemblies together using the appropriate tube segment for your battery group size.

Remove the vent covers and install manifolds assemblies into each battery.

Connect batteries together with 1/4" tubing.

Install water supply tube (a) to one barb and a red cap (b) to the remaining barb.

Connect the bulb pump to the fill line and Insert the other end into your container of distilled water.

Begin pumping the squeeze bulb until it feels rigid. Your batteries are now filled to the proper level.
