Yes, NiMi's lose their charge just sitting there. I have 4 or so C Series
cameras that use them and my photo shoots were on 10 hour walks, I only
turned the live view screen off between shots.
I would up getting a Digipower DPS 9000 7.2V 2200 mAh LiIon battery.
I did a variety of tests, but basically with the fresh 2700 mAh in the
camera, I had to change batteries at least once in 8 hours and after 250
shots, with the DPS 9000 I get over 500 shots and it is just starting to
slow down at the end of the day as it cools off, where as the NiMi's slow
down about 1/4th of the way through their use.
Now I have the E-500 and the Li Ion battery in this just blows me away, I
have a spare, but don't use it until I know the other battery has had many
hundreds of shots or have a long day to take pictures in.

What suprised me was how quick Ni Hi lose there charge. I recently bought an
all singing all dancing
Hannell charger which has a charge meter etc on, it refreshes the batteries,
detects bad cells etc.
I charged up some new 2700 batteries and within a week with no use they had
lost 30% of the charge.
There are apparently some new sanyo batteries called eneloop?? they are
reported to hold 85% of there
charge after one year, a guy from the Oly forum on DP review has given
positive feedback on there
performance, I am about to order some and give a try, they are approx 10ukp
for a set og 4 if I recall.
