Just a word of advise, if you try using regular alkaline batteries in the digital camera itself, you will always be disappointed. Regular Alkalines will drain in some cameras just by turning it off & on 5 or 6 times.

I have alwas used NiMH in my digital with good luck. But it isn't in a game camera, it is sitting on my table at home and my wife takes pictures of the kids almost daily. I really only have to charge the batteries like once a month. But it is not apples to apples.
