Having worked with and around electric golf carts for more than 20 years. I am here to tell you you cannot accurately test golf cart batteries with a common load tester like you can automotive batteries. They need to be tested as a pack and then individually for voltage. It is very wise to test them with a hydrometer also. You can tell the state of charge for each cell with a hydrometer. Doing this test will let you sometimes shuffle batteries around to get the weak ones all together and the stronger ones in another cart. That will allow the batteries to all charge at the same rate. One weak cell in a pack will make the charger boil all the other batteries trying to bring the weak one up to par. Golf cart chargers depend on seeing the voltage rise over the rated voltage to kick the charger off. The multi meter is important in checking batteries and also the load tester, but when you really want to know the health of your battery, take a reading of each cell with the hydrometer. Gene Davis
