What is a Millennium Evo battery watering system?

The Millennium Evo Battery Watering System simplifies the difficult task of watering industrial batteries. The system consists of automatic shut-off valves, interconnected with tubing, that replace the existing vent caps. A quick coupling allows the system to be connected to a water supply. Once connected, water flows into each cell until it reaches the correct level. A flow indicator built into the water supply tells the operator when filling has been completed. The entire process takes just 30 seconds per battery.

What can a battery watering system do for you?

Save Time: Take a 15-minute hassle and turn it into a 30 second task!

Improve Safety: Fill batteries without removing vent caps to avoid acid burns, ruined clothing, and noxious fumes.

Optimize Battery Life: Over-filling and under-filling batteries both result in lost capacity. Millennium Evo fills to the correct level every time, giving you optimal battery life.

Save Money: Contact Flow-Rite or your local dealer to receive your custom payback analysis showing your operation’s labor cost savings.
