The wife and I have only recently ventured into the world of Digital Photography and
we were very disappointed with the cycle life of rechargeable NiMo batteries. We then
discovered Rayovac Hybrids (NiMh). They are fantastic. You can pop them into a
charger whenever you feel like it...no charge memory problems. They last like forever,
and if you charge some up ahead of time, they hold that full charge for several months in
storage. They come out of the package ready to shine.

We found ours at Circuit City. They're all we use now.
