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.
This could be a 9 volt battery or 6 volt dry cell for rejuvenation of small, low voltage battery packs, or a 12 volt car battery or charged up power tool battery for higher voltage power packs. If you need more than 12 volts, you can connect two 12 volt batteries in series as shown below to get 24 volts.
