Mike I'm not familiar with the moultrie, but I would'nt think you would have to change the batteries in your camera that often, I have a Hawkeye camera and it will take about 3 or 4 rolls before having to replace any batteries. What size batteriesa does your camera take, if they use standard type batteries you can get the duracell ultra with the little tester on the side, thats what I use and it will tell you when the batteries are weak. I'm not sure about the 6 volt if you can get one of them with a tester one it or not.

THE NRA, WHERE WOULD YOU AS A GUN-OWNER BE WITHOUT THEM.
