MINERAL CONTENT
For the longest battery life, use distilled water in batteries. However, if tap water is to be used, be sure the min-
eral 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.
See Battery Replacement on page 14-1.
BATTERY CHARGING
See General Warning, Section 10, Page 10-1.
CAUT ION
• Only IQ Plus chargers should be used with IQ Plus vehicles. Long-term use of a PowerDrive
battery charger with IQ Plus vehicles will damage the batteries.
The charger supplied with the Club Car electric vehicle resolves the most common problems associated with
battery charging. Undercharging and overcharging are prevented provided the charger is allowed to shut off
by itself. Also, all cells are automatically given an equalization charge at low current, which prolongs battery
life. Batteries should never be left in a discharged state, as this too affects the internal components and can
reduce the capacity of the battery. The batteries should be charged every day they are used. However, the
batteries should not be charged if they have not been used.
CHARGER SHUTS OFF AFTER 16 HOURS
This may be due to 1) new batteries, 2) hard use, or 3) cold temperatures. A catch-up charge may be neces-
sary when these conditions are present. On those days when all or some of the vehicles do not get used,
