I also have a Stealth Cam DIGRC-XTR and it is definately a battery HOG. I have tried all kinds of batteries (including the ones made for digital cameras) and cannot get more than 4-5 days oout of a set. Has anyone out there tried hooking a 12 volt to the solar charging port on the bottom of the cam? I am to the point of trying it myself and if it destroys the cam then at least that will give me a reason to buy a cuddleback!
