Even when they're new, I've been told that Nicker Metal Hydride
batteries
lose about 1% of their charge everyday even when not being used and out
of
the camera. That's just the nature of the beast. The new Lithium ion
batteries are much better that way.

Hi Punk... (somehow that doesn't feel right

I agree that they do self-discharge as all batteries do;
but I think that 1% per day is greatly exaggerated...

NiMH batteries have some interesting drawbacks, here's a good URL:

Couple the facts that NiMH batteries are only good for about 500 cycles,
deep discharges shorten battery life, and that they can self-discharge 15%
to 20% within the first day, and with moderate use, it doesn't take terribly
long before you're just not getting much use out of them.

I have a good number of AA NiMH batteries that I've used on my digital
camera (light to moderate duty) for about two years, and they still work -
but don't hold nearly as much as when new, and if I want a lot of use out of
them, I have to grab them straight from the charger.
