Battery life isn't nearly as good as a lot of trail cameras, but it's a lot better than my old Moultrie D40's. It takes 6 C batteries, and I think I could get at least 6 weeks out of them, at least in the summer with warmer temps. However I normally run it on a Stealth Cam 6 volt external battery. When I'm baiting regularly I get two to three hundred pictures per week.
What I like most about the camera is the color night pictures and very little blur, like you usually will get with most infrared cameras.
