You should not have a problem getting a couple of weeks out of it. I have gotten a month easily from mine. It takes great pics. The only thing is the trigger time is a bit slow compared to the top of the line models. Just make sure you put it in front of a scrape, bait, or facing towards a well used trail to allow time for a trigger. If the critter does'nt stop, you may get alot of empty pics. Good luck!
