Battery Charger – Ferroresonant BATTERIES
As long as the charger is allowed to shut off by itself, the batteries will be fully charged. Overcharging and
undercharging will normally be prevented.
Batteries should be put on charge even if they have been used for only a short period (10 minutes). The charger is
automatic and will turn off when batteries are fully charged. If the charger does not seem to be operating properly, or
if the batteries seem weak, contact your local Club Car distributor/dealer.

PLUG AND RECEPTACLE

The charger cord, plug, and receptacle are wear items and should be inspected daily. Visually inspect them for cracks,
loose connections, and frayed wiring; they must be replaced when worn or damaged. If charger plug or receptacle
show signs of corrosion or the plug is difficult to insert or remove, the receptacle contacts and plug terminals should
be cleaned with a good electrical contact cleaner or lightly sprayed with WD-40 ® brand spray lubricant. The plug
should then be inserted and removed several times to ensure ease of insertion, ease of removal, and good electrical
contact. See following NOTE.
NOTE: If the warning tag has been damaged or removed from the DC cord, have it replaced immediately.

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 necessary when
these conditions are present. On those days when all or some of the vehicles do not get used, check the batteries
for state of charge. Any battery with a specific gravity lower than 1.250 will need a catch-up charge. If the problem
continues after a catch-up charge has been performed, check the battery charger. Refer to the appropriate battery
charger maintenance and service manual. See Section 19 – Battery Charger.

DEEP-DISCHARGE

Never discharge batteries to the point the vehicle will no longer operate. This will considerably shorten the cycle life of
the batteries, and may permanently damage the batteries. It is possible the batteries will not accept a charge if they are
completely discharged. The deeper the discharge, the harder it is on the batteries. For this reason, it is recommended
that electric vehicle batteries be charged after each use (provided the charge cycle will not be interrupted and the
charger will be allowed to shut off automatically). Placing the batteries on charge after each use reduces the depth of
discharge and prolongs battery life.

EARLY EXCESSIVE DISCHARGING

When vehicle batteries are new, they do not reach their full capacity until they have been used and recharged 20 to 50
times. If they are excessively discharged early in their life, their effective service life will be shortened. It is advisable to
limit the use of any vehicle with new batteries for at least the first four weeks and then gradually increase their range.

INCOMING AC SERVICE

Make sure the incoming AC line service is sufficient. If circuit breakers are tripping, fuses blow during the night or the
charger does not give the required starting rate when sound batteries are put on charge, an AC line problem exists.
The electrical service to the vehicle storage facility should be sufficient to deliver adequate voltage and current to each
charger with all the chargers turned on. If not, consult your local power company or electrical contractor. Refer to the
appropriate battery charger maintenance and service manual. See Section 19 – Battery Charger.
