In the middle of last year I bought a digital SLR that runs on 4 x AA
cells. The instructions say that alkalines are OK for checking the
camera, etc, but 2400 mAh NiMH are the preferred option for normal use.

However, I've yet to find a 2400 mAh cell that, according to my chargers,
can hold more than 50% of the rated charge and I've tried some that can
barely manage 500 mAh. I've tried Maplins hybrids, cheapo budget
batteries, and Ansman, but none seem as good as a vanilla set of
alkalines. This has never been a problem with NiCDs of all sizes (except
those made by GP), but all the NiMH cells I've tried have been
disappointing to say the least.

I have decent peak chargers: a PC-controlled Vencon UBA III+ and a Pro-
peak Prodigy II set up for 500 mA charge and 250 mA discharge. Both
chargers measure input charge and capacity on discharge.

I'm asking here because I've never had a good experience with NiMH - not
with this camera or in the past.

I know there are people on r.a.s who know a lot about batteries. So, what
brands of NiMH battery have you had good results from, i.e. that actually
do what it says on the tin?
