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.
The voltage on a fully charged battery should be about 12.7-12.8 volts. If it's higher, the charger is on. Batteries will usually fail to start an engine at 12 volts or less. This is dependent on the age of the battery. A new, but depleted battery may only fail to start at a voltage as low as 11.5 volts. Be wary of electric panel meters; they are often very inaccurate.
