HydroPure Battery Filling Unit

The system comes with everything you need to make your own pure water right from your own tap: a wall-mounting plate, one high-capacity Deionizer cartridge, purity light, hose hanger, quick connects and input and output hoses. Installation takes just minutes — and replacing spent cartridges takes just seconds.

Battery water should be free from metallic impurities because they can affect cell voltages and self-discharge. Also to be limited are calcium and magnesium compounds found in hard water because these may cause mossing and dendrite growth through the separators. Note that these impurities are dissolved in the water and cannot be removed by conventional filters.
