MAINTENANCE

Read all of this manual to become thoroughly familiar with this vehicle. Pay particular attention to all Notices, Cautions, Warnings, and Dangers.

•

The charger is automatically turned off during the connect/disconnect cycle and therefore no electrical arc is 
generated at the DC plug/receptacle contacts.

In some portable chargers, there will be a rattle present in the body of the charger DC plug. This rattle is caused by an internal 

magnet contained within the charger plug. The magnet is part of the interlock system that prevents the vehicle from being driven 

when the charger plug is inserted in the vehicle charging receptacle.

AC Voltage

Battery charger output is directly related to the input voltage. If multiple vehicles are receiving an incomplete charge 
in a normally adequate time period, low AC voltage could be the cause and the power company should be consulted.

Troubleshooting

In general, troubleshooting will be done for two distinct reasons. First, a battery that performs poorly and is outside of 
the manufacturers specification should be identified in order to replace it under the terms of the manufacturer’s war-
ranty. Different manufacturers have different requirements. Consult the battery manufacturer or the manufacturer’s 
representative for specific requirements.

The second reason is to determine why a particular vehicle does not perform adequately. Performance problems 
may result in a vehicle that runs slowly or in a vehicle that is unable to operate for the time required.

A new battery must 

mature 

before it will develop its maximum capacity. Maturing may take up to 100 charge/dis-

charge cycles. After the maturing phase, the older a battery gets, the lower the capacity. The only way to determine 
the capacity of a battery is to perform a load test using a discharge machine following manufacturer’s recommenda-
tions.

A cost effective way to identify a poorly performing battery is to use a hydrometer to identify a battery in a set with a 
lower than normal specific gravity. Once the particular cell or cells that are the problem are identified, the suspect 
battery can be removed and replaced. At this point there is nothing that can be done to salvage the battery; however, 
the individual battery should be replaced with a good battery of the same brand, type and approximate age.

HYDROMETER

A hydrometer 

(

P/N 50900-G1

) 

is used to test the state of 

charge of a battery cell. This is performed by measuring 
the density of the electrolyte, which is accomplished by 
measuring the specific gravity of the electrolyte. The 
greater the concentration of sulfuric acid, the more dense 
the electrolyte becomes. The higher the density, the higher 
the state of charge.

To prevent battery explosion that could result in 
severe personal injury or death, never insert a 
metal thermometer into a battery. Use a hydrom-
eter with a built in thermometer that is designed 
for testing batteries.

Specific gravity is the measurement of a liquid that is com-
pared to a baseline. The baseline is water which is 
assigned a base number of 1.000. The concentration of 
sulfuric acid to water in a new golf car battery is 1.280 
which means that the electrolyte weighs 1.280 times the weight of the same volume of water. A fully charged battery 
will test at 1.275 - 1.280 while a discharged battery will read in the 1.140 range.
