This professional quality deionizer system is not just a filter, which only removes particles, but a real ion-exchange medium that electrostatically removes dissolved impurities. Purity is comparable with distilled water and ideal for batteries.

Lead-Acid Battery Water Deionizer System

Maximize battery performance with pure water from the tap.

Our water deionizer reduces the high cost of buying bottled water and is more convenient. Each disposable cartridge purifies about 600 gallons of water (2400 liters). Why let impurities in your water reduce the life of your battery, when this system is so easy to use and cost effective?

How Does it Work?

Inside the deionizer, tap water is passed through a cartridge containing beds of cationic and anionic resins which electrostatically remove impurities. The result is very pure water. When the cartridge is exhausted, simply replace it with a fresh one. Cartridges are available for a fraction of the cost of distilled water, enabling you to produce your own pure water for less money than it would cost to buy it.

Why Use a Deionizer for Battery Water?

Metallic impurities in water can poison the battery, affect cell voltages, and increase self-discharge, all of which can result in shortened battery run time and reduced battery life. Calcium and magnesium compounds found in hard water 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. Using deionized water is a simple and effective way to maximize battery life.
