I agree with using Lithium batteries as well. They cost about 3x as much but WELL worth it. I use them in all my Trophy Cams and have had 4 cameras up for 2 years (running 6 months a year, July to January) and all are still on full charges. I don't run my cameras in 0 degree tempatures but they are running from 15 degrees to 90 degrees and I usually get about 4000 pictures a year. I went with just the regular AA batteries for a while but have learned the better the batteries the better than camera runs.
