WATER QUALITY

To keep batteries in good working condition, the purity of water used is very important. Distilled water is quite pure
and is the most common type of water used in batteries. Other acceptable types are deionized water and water from
reverse osmosis. Ordinary tap water should not be used because it contains an excessive amount of impurities that
will degrade battery performance.
Distilled water is produced by distillation, a process in which water is boiled, the steam is collected and then condensed
back into water. This process creates a finished product free of minerals, having left all the impurities in the original
water sample. Club Car, along with our battery manufacturers, highly recommends that distilled water be used in
electric vehicle batteries.
Deionized water is the purest form of water, but it is also the most expensive. Deionization removes all ionizable
particles (organic and inorganic) from water through ion exchange. Positively and negatively charged ions are removed
from the water and replaced with H+ and OH- ions. When these two ions are combined, they form H2O, or purified
water.
Reverse osmosis is a method of removing solids from water by forcing it through a membrane. The membrane
rejects all solids while allowing purified water to pass through. The choice of membrane determines the amount
of impurities that the water may contain.
Water from municipal supplies, ponds and wells usually contain detrimental levels of dissolved minerals and chemicals.
If using tap water, it is important to use an in-line deionizer to remove impurities that can damage batteries and
significantly reduce battery life. If tap water is used without a deionizer, regular water analyses must be conducted to
check for impurities because water companies commonly revise their additives on a periodic basis. The following
chart lists the maximum allowable minerals, solids, and contaminates in parts per million and their impact on battery
performance. Your local water company should be able to perform testing and compare their results to the chart.
If using tap water, Club Car's Service Parts Department offers two different deionizer systems: one for vehicles
equipped with the Single Point Water System (SPWS) P/N AM1240701 and the other for vehicles without SPWS,
P/N AM10974.
