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.
1 The actual voltage of AAA, AA, C, and D (and 9 volt) batteries weakens as the batteries are drained of charge. 2  Different types of batteries start out with different maximum voltages. 3  NiMH batteries, in the sizes AAA, AA, C, and D, provide a maximum voltage of about 1.40 to 1.45 volts.
