are you using the moultrie rechargable batteries and the moultrie charger? I use both (about $10 each) and i usually get 2-3 weeks out of mine on a charge. but lately this cold weather has got em runnin out pretty quick. I once forgot my rechargable batteries and got some junk cheapo 6V batteries and it only lasted a day or 2, i'd say go with the rechargables, a much better deal in the long run. just make sure though that you're spraying your camera and the tree down with scent killer when you put it up, and maybe even use rubber gloves. My buddy and i have both had cameras swatted at by bears and one of my older 35 mm cams has a puncture in the sensor from a bear. so make sure you're using a bear box or scent killer if you know there are bears in the area. Also, i'd recommend installing the camera and turning it on then placing the bait, in that order, so as to not get any scent from the bait on your camera.hope this helps
