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)?

If you compare two 'fresh' batteries, one alkaline and one NiMH, you'll find
that the NiMH has a much higher capacity. But the NiMH *also* have a much
higher self-discharge rate. If the application uses power at anything like
the 20-hour discharge rate, the NiMH will win hands down. But if the

ANS2300 - NiMH - 1.2V - 2300 mAh (Ansmann)

ANS2400 - NiMH - 1.2V - 2400 mAh (Ansmann)
RB102746 - NiMH - 1.2V - 2300 mAh (Uniross)

RB100880 - NiCd - 1.2V - 800 mAh (Uniross)
RB104358 - NiMH - 1.2V - 2500 mAh (Uniross)

4106 - Alkaline - 1.5V - 2600 mAh (Varta)
MN1500 - Alkaline - 1.5V - 2700 mAh (Duracell)

e2 lithium - 2900 mAh (Energizer)
alkaline copper top - 2850 mAh (Duracell)

NiMH are quickly catching up with alkaline primaries.
