To test the quality and power of a golf cart battery, you’ll need a voltmeter, a load tester, and a hydrometer. The voltmeter will connect to the terminals at the top of the battery to read its voltage. The load tester uses the same terminals to pump the battery full of current and assess how the it handles high levels of amperage.
