It is important that you use purified/deionized water to water your batteries. We offer solutions for deionizing water quickly and easily, but first, let’s look at why water should be deionized.
Tap water contains minerals, like calcium, magnesium and iron, and other impurities. The amount of impurities vary depending on your location and water source. When tap water is used to water batteries, the minerals within the water can react with the battery’s components. This alters the chemical composition of the electrolyte and plates, causing damage, corrosion and reducing the battery’s lifespan and ability to hold a charge.
Deionized water is water that has had most of the dissolved solids, like minerals or inorganic materials, removed. An ion is a molecule that has a positive or negative charge. Therefore, to remove ions from water, use an ion-exchange resin which exchanges positive ions (cations) and negative ions (anions) for hydrogen and hydroxyl ions. After passing through the ion-exchange resins, what’s left is highly purified water.
At Battery Watering Technologies, we offer our own solution for deionizing water. Our deionizer kit easily and inexpensively removes harmful impurities from water with a simple system. The kit includes an input and output hose and connects to your choice of a Direct Fill Link, Manual Watering Gun or an approved competitor filling device. It can also be used to fill a tank (link our AquaSub).The deionizer kit uses a replaceable, mixed bed resin cartridge to route water through the system and undergo the deionization process. How many gallons of water you can expect to flow through the deionizer before having to replace the cartridge depends on the level of dissolved solids in your water.
We also offer a water quality tester (WQT) which tests the total dissolved solids (TDS) in a given volume of water. Total dissolved solids would include charged ions, like minerals, salts or metals dissolved in the water. This is typically measured in Parts per Million (ppm). If your WQT indicates <100 ppm, the water should be fine to use (doesn’t require deionizing), if your water is between 100 ppm and 200 ppm, the water is typically okay for use, but you may want to consider a deionizer. If your water is >200 ppm, water treatment is needed, and you should purchase a deionizer.
Using a deionizer on water that is over 200 ppm will prevent corrosion and extend the life of your batteries. Our deionizer kit is simple to install and it’s long-lasting. All you have to do is replace the interior cartridge once the purity light reads “service.” For more information on the Battery Watering Technologies deionizer kit, visit our website.
