Picked up a Duracell charger with four AA NiMH batteries. I searched until I found one that said "charges 1 to 4 batteries". It's the one that says "15 minute fast charge", and that it shuts off completely when the batteries are charged.

They all came out of the box with a hair over 1.5v (I have an "inexpensive" analog multimeter). I love that rechargeables now come pre-charged.

I put a pair in the camera, put everything else away, and we'll see what happens.

Thanks again to all!
