There are a few ways that you can revive a 12-volt golf cart battery. One way is to use a battery charger to charge the battery. Another way is to use a jump start box. Finally, you can also use a solar panel charger.
If you are using a battery charger, make sure that the voltage is set to 12 volts. If you are using a jump start box, make sure that the amperage is set to 12 volts. If you are using a solar panel charger, make sure that the wattage is set to at least 120 watts.
Once you have the right charger, connect the battery cables to the battery. The black cable should be connected to the negative terminal (the – terminal), and the red cable should be connected to the positive terminal (the + terminal).
Once the cables are connected, turn on the charger. The charger will start charging the battery. Once the battery is fully charged, disconnect the charger and reconnect the cables to the battery.
