How do you know if your golf cart batteries are bad?

Answer 1

If you have a manual charger follow the charging instructions. After a full charge, do an On-Charge Voltage Test. Get your volt meter out and set it to 200v dc with the charger on. We will be checking individual battery voltages, start with the #1 battery (where the positive lead goes to the cart) placing the positive lead of the voltmeter on battery positive and the negative lead of the voltmeter on battery negative, move down the line until the last battery. For 36v carts with six 6v batteries we want each battery to read at least 7.0v. For 48v carts with six 8v batteries were looking for at least 9.3v on each battery. Put your safety glasses and safety gloves on. Remove all battery caps. Get your hydrometer out and start with the #1 battery take your sample from each battery cell and write it down. You should have readings of 1100 to 1300, 1100 being close to water and 1300 being acid. Start with the #1 battery. If there is a difference of 50 points or more between cells you have a bad battery. Here is an example of a good battery. 1265 1275 1265 Here is an example of a bad battery: 1265 1175 1265

Answer 2

You can put them on a charger and see if they accept a charge.

You can also use a battery tester (though you will need a tester large enough to handle Golf cart batteries).

Answer 3

Rechargeable batteries eventually wear out. They probably need replaced.
