Universal 36 Cell (TBU)

  • A Universal battery watering system will fit on nearly any make and model of battery, no matter the layout of your battery bank. Everything is provided for the system, however the tubing is not cut or attached to any of the valves.

    All battery watering systems are equipped with self-regulating valves that are assembled with clear tubing. Pairing the quick-connects allows water to flow through the tubing and into the valves, filling each cell with the precise amount of water. Water your batteries in a matter of seconds!
