Use Identical BatteriesMake sure the batteries are the same capacity and use type. Connecting different types of batteries can cause shortened working life of the batteries, fire or explosion.ConnectionsConnect the positive terminal of the first battery to the positive terminal of the second battery. Connect the negative terminal of the first battery to the negative terminal of the second battery. Connect the positive terminal of the first battery to the negative terminal of the load. Connect the negative terminal of the first battery to the negative terminal of the load.ConsiderationsConnecting batteries in parallel preserves the voltage. Two 12-volt batteries connected in parallel will provide 12 volts of energy.
