Read the multimeter. A 12-volt deep cycle battery in good condition has a reading of between 12.4 and 12.7 volts; consider a replacement battery if the reading is lower than 12.4 volts. A 6-volt battery in good condition will read between 6.2 and 6.3 volts.

Can you test a deep cycle battery?

You can test your deep cycle battery's charge level in several ways. The most common methods use a multimeter, voltmeter, or watt meter.
