The battery of the electric Golf cart should often be checked and serviced in order to maintain them at their top performance. The main battery types are the 36v and 48 v battery. Here we discuss on how to check them.

First step you have to do is to charge the battery to its peak. If it has an automatic disconnection facility, leave it to charge until it is fully charged. If it does not have such a facility, follow as per the directions given in the manual.
Once it is fully charged, it is time for conducting the On-Charge Voltage Test. For this test set the voltmeter setting to 200V dc. Then plug it to the charging point again and start the test. All the battery cells have to be tested individually. Start by checking the first battery and slowly move downwards. Make sure to make a note of all the individual battery readings. Place the +ve terminal of the voltmeter on the +ve of the battery terminal and like wise connect the -ve terminals too. Now check the voltmeter reading. For a good condition battery we need a voltmeter reading of 7.0V for carts with 36V (6 x 6V battery) and a reading of 9.3V for 48V carts (6 x 8V battery).
Replace the battery if:
1) If the 36V battery does not give a reading above 7.0V and if its does not give an error correction of + or - 0.5V of the other batteries.
2) If the 48Vv battery does not give a reading above 9.3V and if its does not give an error correction of + or - 0.5V of the other batteries.
A Hydrometer test can be conducted on both the 36V as well as the 48V battery. This test is conducted without the charger plugged ON. Make sure to wear the protection devices for your safety. Remove the battery caps and connect the hydrometer terminals to the battery terminals. Check each battery individually and note down the readings. The reading should be between 1100 and 1300. (1100 being near to water and 1300 near to being acid). If you find a 50 point or more difference between the battery cells, then it is time to change your battery.
