Thanks for the info. I'll pick up a set of the energizer and try them out. The ones I have are Sanyo 1650mAH I bought a couple years ago. They worked well at first, ran my digicam through two 16m cf cards on the same set of batteries. Now I have to swap around just to get the camera to turn on. I didn't treat them as well as I should, the digicam forums all say to keep them together in sets and such, I would just grab the first three that were charged. I got to where I stopped using them in anything else because I feared that they would be dead when I tried to use them.
