Regarding battery life, if you put over bait/feeder and set it to take pictures on zero to little delay, batteries will drain just like a normal camera. You can play with the settings and save life by having a delay between pictures taken but may miss the pic your looking for in that case. I've since moved mine to focus it more on trails. Out 3 weeks and battery life still on full. It is really about how you plan on using it. I did have it on a feeder earlier in the year and batteries still lasted a few weeks before going dead. I'm sure there are better quality batteries that may extend the life. I just use the regular run of the mill energizers or whatever is on sale.
