I have a moultrie d40 and i had it out for two weeks and the battery power was down to 50% i didnt change them since i did not have any. i went and checked it sunday(two weeks later) and it had 40% power and it had only taken two pictures. my question is will it completely shut down once it gets to a certain amount of power. I had to manually turn it back on to see how many pictures it took.
