An aaa or triple a battery is a standard size of dry cell battery commonly used in low drain portable electronic devices.
We have started the test of the 1 5v aaa duracell alkaline batteries as we normally do with a low constant current discharge rate of 0 1a and the result we got was 970 mah as capacity and that is a very good result close to 1a.
Warming the battery increases the capacity slightly and cooling decreases capacity.
Evidently for high current applications the rechargeable battery is a much better choice both for amp hours and for keeping the voltage high during discharge.
Just found this online.
A circuit that draws 10 ma powered by a 9 volt rectangular battery will operate about 50 hours.
