To determine whether your cart batteries are the culprit or not, you will be required to take a digital test. It will help you to read and test every single battery. You have to charge your cart entirely before you test the batteries.

Keep testing your volts after every fifteen minutes when the Charger is running. Once you start to see the same voltage, again and again, it will show that up to what extent your batteries’ voltage will rise. It may give you a clear idea about how well or bad are your batteries.

If you have a six-volt battery with a thirty-six volts system, you will want to check the readings of around 6.2 or 6.3 volts for each battery. If the results show something like, on a six-volt golf cart battery, it offers four-volt charges; it merely means you have a bad battery. It would be best if you replaced that battery as soon as you can.

One battery can affect the performance of the entire set to turn down. If you have a system with eight batteries in a forty-eight-volt system, you will be required to check the readings around 8.2 or 8.3 volts for each battery. If it shows something like a six-volt charge on an eight-volt battery, that means you have a bad battery. It would be best if you replaced that battery.
