per million and their impact on battery performance. Your local water company should be able to perform test-
ing and compare their results to the chart.
If using tap water, Club Car's Service Parts Department offers two different deionizer systems: one for vehi-
cles equipped with the Single Point Water System (SPWS) P/N AM1240701 and the other for vehicles without
SPWS, P/N AM10974.
Mineral Content
For the longest battery life, use distilled water in batteries. However, if other water is to be used, be sure the
mineral contents are below these levels:
VIBRATION DAMAGE
The battery hold-downs should always be tight enough to keep the battery from bouncing. Battery life may be
severely shortened if the battery hold-downs are too loose. Battery hold-downs should be tightened to 40 in-
lb (4.5 N·m). Excessive vibration causes the plates to shed prematurely and shortens the life of the battery. It
may also cause acid to leak out of the vent caps and corrosion to build up on surrounding metal parts. The
acid which is lost reduces the capacity of the battery and cannot be replaced. Battery hold-downs should NOT
be so tight as to crack or buckle the battery case. This may cause leaks which would dry out a cell or cause
internal short circuits.
