I know AA batteries are the most convenient to get and cheap but here's my observation after owning many digital cameras. The propriatory batteries in my Canon S400 & S300 last a long time, maybe 200+ pictures but so do the AA batteries on my other digital camera, the difference is that the AA batteries drain on their own, a fully charged battery seems to lose it's charge in 2-3 weeks but the propriatory batteries on my Canon's stay charged for months and this is important as I leave the camera in my car and I don't want to charge it every week, I can leave it in there and I see something I want to take a picture of, it's ready to go. I've tried different brands of NiMh AA batteries and they're all the same.
