How does the capacity of a Duracell-brand AA cell (Duracell ordinary
or Duracell ultra) compare to one of the high-capacity NiMH cells (eg
2100 mAh)?


I am assuming, of course, that any applicance using the cells would
work down to the 1.2 volts of the NiMH.

A quick google returned this page:
http://www.jr.com/JRProductPage.process?Product=882423 stating 2850mAh.

NiMH and LiON reghargables do better in digital items though (digital
cameras, MP3 players, mobile phones) because the current drain is not a
constant drain, but a high drain pulsed on and off (think memory clock
cycles). A 1800mAh battery would probably outperform Duracells in a digital
camera.

ISTR my camera manual saying not to use ordinary alkaline batteries because
they overheat with the large current drain, so you have to use photo
alkaline batteries.
