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) CC P/N AM1240701 and the other for vehicles without SPWS,
CC P/N AM10974.

BATTERY CARE – VEHICLES EQUIPPED WITH THE SINGLE-POINT WATERING SYSTEM
WARNING
• When replacing batteries in the Single Point Watering System, place the battery cap from the new
replacement battery onto the used battery being removed from the car. Important safety warnings on
the battery cap must remain with the battery after it has been removed from the car.
To keep batteries in good working condition, follow this maintenance program on a regular basis:

EFFECTS OF IMPURITY
-
-
Corrosion of positive plates
Slight self-discharge of both plates
Self-discharge, reduces life, lower
on-charge voltage
Self-discharge, can form poisonous gas
Increase of positive plate shedding
Loss of capacity in plates, greater loss
in positive plates
Increased self-discharge, lower
on-charge voltage
Increased self-discharge, lower
on-charge voltage
Reduced life
Intense lowering of on-charge voltage
Increased sulfation of negative plate
Plate corrosion, loss of capacity, reduced life
Violent self-discharge, lower on-charge voltage
Positive plate shedding
Slight self-discharge of negative plates
