AAA batteries can be measured using voltage for the most part. They are rated at 1.5 volts each and depending on the battery will depend on how much wattage is produced from those volts. It seems on average that AAA batteries have a measurement of a bit less than 2 watts per battery.
Similarly one may ask, how many watts is a AA battery?
A typical AA battery contains about 3.9 watt-hours, or 0.0039 kilowatt-hours, which is plenty of energy to keep your small flashlight bulb lit for hours before you have to change the batteries.
Keeping this in consideration, how many watts is 8 AA batteries?
You have 8 AA batteries, which deliver 2800 ma/h at 1.5 V each. If you connect them in parallel, then you have a 2800x8 ma/h 1.5 V battery pack.
Starting the engine will require 250 amps for a half second, and the most current a 1.5-volt AA battery can produce is 10 amps. Given the above, you'd need to start with a string of eight AAs to get your necessary 12 volts.
