Ampere-hours far from tell you the whole story on the suitability of a
particular battery - discharge rate - type of load (resistive or
inductive "looking" and it will be the latter in a lot of consumumer
products - DC to DC convertors etc) - constant current to constant
power load ?

To my environmental shame, I've given up on NiMH for my digital camera,

So have I, again to my shame, because they simply didn't last long enough.

I don't use the display unless I have to.

I think that's a very important point. The display eats power.


I'm really surprised at this actually... I've run my camera (Canon
Powershot A40) on NiMhs ever since I bought it. I always carry a
spare set (4) of charged cells around, and never worry about how long
the display is on for or how much I use the camera; if I have to
change the cells during the day I can always guarantee there'll be
more than enough juice available from the second set to last till I
can get back to my charger that evening. (Only problem comes when I
find the kids have raided my AA's to power their GameBoys again! cue
sense-of-humour failure from pa...)

I guess it depends on how much you use the camera during the day,
whether it auto-powers down (mine does), etc etc - but to be honest
I've never felt that alkalines lasted any longer than a set of freshly
charged NiMHs.
