Have you considered Eneloops? Not sure if others like them or not.
Put it this way: I bought a Canon SX110 a few years ago, and was very disappointed when I consistently got less than 100 shots using alkaline batteries. I kept thinking, "either I'm buying old batteries off the shelf, this camera is a battery hog, or the chip is shutting the camera down when it thinks the batteries are low, even though they aren't."
It wasn't unusual to get only 60 shots on a pair of Duracells, and that's without flash.
Then I bought a four-pack of Eneloops for ten bucks (came with the charger) at Best Buy and consistently got (no joke) 900 shots for two batteries, and about half that with consistent use of flash.
Those things are stupidly strong. It's like they are possessed by ghosts.
