General Comments

I have a total of 8 Energizer AA size 2500mAH NiMH batteries in use, with 4 of them powering an Olympus C740UZ digital camera, and a pair each in Sony DSC-S60 and DSC-H1 cameras. I've been using them for over a year and they sometimes get pretty heavy use, but they always provide reliable power, even when taking a lot of flash photos.

By comparison, 8 Sanyo 2100mAH NiMH batteries I originally used in the C740UZ had lost a lot of their capacity by the time they were a year old, even though they hadn't had a lot of use.

The Sony cameras are quite picky about what kind of batteries are being used. They will operate for only minutes with some cheap Chinese ones, but take a lot of photos with these Energizers.

In common with other high capacity NiMH batteries, these ones will go flat by themselves in a few weeks when left just sitting around. The moral of the story is to always fully charge them just before you use them.
