Note: Battery capacity is measured in Amp-hours. This corresponds
to the maximum current that can be delivered by the battery
for 20 hours, before the voltage drops below 0.8 Volts.
So, a capacity rating of 2,870 milliAmp-hrs means that the battery
can deliver 143.5 mill-Amperes of current for 20 hours.
If the average voltage over the 20 hours is 1.15 Volts
(half-way between 1.5 and 0.8 Volts),
2,870 milliAmp-hrs corresponds to about 3.3 Watt-hours
of energy
(0.1435 [Amps] * 1.15 [Volts] * 20 [hours]).
AA Alkaline batteries have been
shown
to produce a peak of 3.75 Watts
of power each.
This corresponds to 10 Amps of current when shorted.
