You ought to be able to find the info on a Duracell web
site. A couple of years ago, they said 2215 mAh at a cutoff
voltage of 0.8 volts. Problem is, most modern cameras won't
run with a battery that low,

Asside from that, you must specify the drain rate. Compare the Ah
capacity at 20 hour rate and 1 hour rate. Quite a difference. It
depends on both cell chemistry and structure.

I have a 12V (10 cell), 60Ah set of vented cell, sintered plate NiCd's
that *tested* 500a for 5 minutes to a 9V end point after cold soaking
overnight at -40. Try that with a 60Ah lead-acid battery!
