Go get you a new camera and let it set for a while. You can buy good cameras now for ~$100 and they will last atleast a month, and up to 5-6 months, on a set of batteries. I like the Truth Cam 35 made by Primos. It is a very good camera for the money ($99). Battery life is supposed to last for 30,000 pictures. Last years model would last about 2 months for me. It is an IR flash, so the deer would be less likely to notice. Just my opinion, hope it helps.
