Battery Charging, Continued:
A catch-up charge may be necessary when these conditions are present. On a rainy day or an off day, when
all or some of the cars do not go out, check the batteries in the cars for state of charge. Any batteries with a
specific gravity lower than 1.250 need a catch-up charge. If the problem continues after a catch-up charge
has been performed, refer to Section 23 (Battery Chargers).
Deep Discharge
Never discharge a vehicle’s batteries to the point that the vehicle will no longer run. This will shorten the cycle
life of the batteries considerably, and may permanently damage the batteries. It is possible that the batteries
will not accept a recharge if they are completely discharged. The deeper the discharge, the harder it is on the
batteries. For this reason, it is recommended that cars be charged between rounds. Placing the batteries on
charge between rounds reduces the depth of discharge and prolongs battery life.
Early Excessive Discharging
When golf car 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 car with new batteries to 18 holes per day (V-Glide 36 volt vehicle) or 36
holes per day (48 volt vehicle) for at least the first 4 weeks and then gradually increase their range.
Incoming AC Service
Insure that 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 perfectly good batteries are put on charge,
an AC line problem exists. The electrical service to your car storage facility should be sufficient to deliver 115
volts (minimum 105 volts, maximum 128 volts) and 10.7 amps per charger with all the chargers turned on. If
not, consult your local power company or electrical contractor.
Fleet Rotation
Rotate your cars. Put a different set of cars out first each morning. It is very hard on batteries if the last cars
in at night are the first ones out in the morning and also are required to go 36 holes. Spread the workload
evenly, giving all cars the same amount of play. This will keep your fleet in balance and will not overwork cer-
tain sets of batteries.
Numbering Cars and Chargers
Return the cars to the same charger each night if possible. If the cars are put in a storage facility at random
and a car dies on the course and testing shows the batteries are good, you know you may have a bad
charger - you just don’t know where. Numbering the cars and the chargers and returning each car to its des-
ignated charger each night can be a great aid in troubleshooting a problem.
BATTERY TESTING
Four tests have been developed to test a set of batteries that has not lived up to its expected performance.
Each test becomes progressively more thorough and time-consuming. It is therefore suggested to begin with
the first test and follow through with the other tests until the problem has been found as outlined in the Bat-
tery Troubleshooting Chart (Figure 22-8, Page 22-10). See DANGER at top of page 22-9.
• WHEN A FLEET OF POWERDRIVE SYSTEM 48 VEHICLES IS BEING ROTATED, THE CLUB CAR
CDM (COMMUNICATION DISPLAY MODULE) CAN BE A VERY HELPFUL SERVICE TOOL. BY
MONITORING THE VALUE OF FUNCTION 3 WITH THE CDM, IT CAN BE DETERMINED WHICH
CARS SHOULD BE USED (SEE PAGE 20-22). HOUR METERS CAN BE USED TO MONITOR
USAGE OF V-GLIDE 36 VOLT VEHICLES.
