Water Quality

PREFERRED SOURCES

DEIONIZED WATER
Deionized water is water that has all charged mineral ions removed (example: sodium, calcium, iron,
copper, and chloride).
Obey the manufacturers' recommendation for filter replacement. A clean filter will make sure that the
deionized water quality stays high.
DISTILLED WATER
Distilled water is the most common type of water used in batteries. Distilled water is made by boiling
water, collecting the steam from the boiling, and allowing the steam to condense back into water. The
distilling process results in a water source which is free of minerals that can lead to the degradation of
battery performance and life.

ALTERNATE SOURCES

REVERSE OSMOSIS
Reverse osmosis involves the movement of water through a membrane that lets water pass while
trapping solids. The selection of membranes and usage frequency determines the quantity of solids or
impurities which get caught and hence the purity quality of the filtered water. Because of the variance
in water quality consistency, Club Car recommends the use of the deionizer or distilled water.
TAP WATER
Because of the levels of dissolved minerals and chemicals that can degrade battery performance and
life the use of tap water without filtering should be limited. Regular water analyses must be done to
check for impurities if unfiltered tap water is used.
