How many mAh in AA battery?

Zinc-carbon AA =400-900 mah

Alkaline AA = 1700-3000 mah

:: I believe the above answer to be misleading/misguiding, the question is "How much mA does a single AA battery have?" not how many mAh.

in mA a single AA batter will have about 3.6mA to 4.0mA

it is important to distinguish mA from mAh, if one were to connect a device that required 4.0mA to a power source of 400-900mA this would likely destroy the device. mAh deals more with how long the battery life lasts.
