I bought some nimh rechargeable batteries and a charger for my camera. They
are AA 1.5 v. size.

When I need to test batteries, I use a pretty good Craftsman tester. On
alkaline batteries, when new, they test up to 1.6 volts. I had some of
these nimh batteries on charge for a good while on an automatic charger.
The indicator light had gone out, indicating a full charge.

I wanted to see how much they read. They read from 1.42 to 1.45 volts. Is
this normal? Do they just last longer, but don't charge up as much? I know
they last a LOT longer in my GPS, and have saved me money already in
batteries. In my radios, the nimh runs circles around alkalines or nicd for
lasting.

Just curious.

It's impressive to see the energy storage improvement in Ni-MH
batteries. A few years ago the best AA Ni-MH batteries I could find
stored 1500 maH, now they're up to 2500 maH.

Duracell has a pretty good tech section pdf about Ni-MH batteries at:
