Flow-Rite Battery Watering Systems

Forklift Industrial Battery Single Point Watering Systems


Flow-Rite makes battery maintenance easy with a full line of Single Point Battery Watering systems and flip top watering caps. Fill batteries faster, safer, and more reliably than ever before with Millennium Evo, Pro-Fill, or Qwik-Fill on-board watering systems.

Each application-specific 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. The entire process takes only 30 seconds per battery.

Millennium Evo

Millennium Evo is designed for all of your industrial battery watering needs including forklift, AGV, walkie pallet jack, sweeper, scrubber, locomotive, and standby batteries.


Pro-Fill is the only watering system designed for use on commercial "golf car" style batteries typically found in golf cars, pallet jacks, scissor lifts, sweepers, scrubbers, and small backup power systems.

Pro-Fill RV / Qwik-Fill

Qwik-Fill and Pro-Fill RV Edition are consumer battery watering systems for 12 volt marine deep cycle batteries and 6 volt golf car batteries typically found in bass boats and recreational vehicles.


WaterWise is the world’s first patent-pending flip top watering cap designed for use with automatic watering guns. WaterWise provides quick and easy cell access and has a built-in stop for accurate watering.
