An AA battery is a 1.5 volt battery so if you connected 8 together in series you would have the 12 volts, but you would have no where near the amount of amps necessary to turnâ¦ the engine over.
It should be 12.6 volts, but for a battery that is fully charged and both battery cables disconnected. You will see more and more systems using a 42 volt battery. Basically (12.6v * 3 = 37.8) + charging voltage = 42 volts.
