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 not go below 9.6 volts. A battery with a volt reading less than 9.6 volts means the battery is sulfated and not holding/accepting the charge.
