I have bought some AA Nimh batteries and find that they are vary
slightly bigger than standard alkalines. I'm talking about a
millimetre or two and not much more, but it's enough to make them an
extremely tight fit in devices that have two batteries stacked on top
of each other.
I was wondering whether anyone could recommend to me Nimh batteries
that that don't have this problem of being slightly bigger than normal
ones, and I am looking for 2000mah and upwards.

Thanks

These people make pretty good AA NiMh cells and chargers
