Single-Point Battery Watering System


Eliminate the hassles that accompany battery watering

Proper maintenance and periodic watering are critical to maximizing the performance and life of your Trojan deep cycle, flooded lead acid batteries. But battery maintenance can be a costly, time-consuming, messy job. A Trojan Single-Point Watering System can make the watering process much easier.

Flexible design

Designed to work with flooded deep cycle batteries, it takes the guesswork out of your flooded battery watering. And the flexible tube routing allows the watering system to work with various battery bank sizes and configurations.

Three configurations

The system comes in three configurations: 12V, 24V and 48V. All are designed for single string installations with Trojan Premium, Industrial and Signature line flooded batteries. (For systems with multiple, parallel strings, order multiple systems at the required system voltage.) You can choose from six different kits. There are:

  • Three for the Trojan Industrial line (12V, 24V and 48V)

  • Three for the Trojan Premium and Signature lines (12V, 24V and 48V).

These six kits use different sized vent caps.

Automatic shut-off valves

You can extend the performance and life of Trojan flooded lead acid batteries by maintaining proper electrolyte levels. However, determining that level can be a challenge. The kit includes automatic shut-off valves, interconnected with tubing to replace the existing vent caps. A quick coupling allows the system to be connected easily to a water supply. Once the watering system is installed, water flows to each battery cell until it reaches the correct level. With the built-in flow indicator, you can easily see when filling is complete, which generally takes 30 seconds per battery.

Extend battery life and performance

A properly watered battery lasts longer and performs better. Overfilling a battery can result in loss of acid, while charging with low electrolyte levels can result in permanent damage to the lead plates. Both can result in loss of capacity and life expectancy.


Filling your deep cycle batteries without removing the vent covers means you avoid battery acid burns, poisonous fumes and ruined clothing.
