Yes. I charged mine as soon as I got them. They lasted over a month, and have worked flawlessly down to -13 degrees. You know, I've heard a lot of complaints about the stealth cams on here but I've had minimal problems with mine, and I have two of them. The only "problem" I've had is with the rewind, and even then I manual rewind mine everytime I pick it up anyways. I may upgrade to a digital this next year, getting a little tired of developing film. Gets kind of expensive when you're bringing in 4+ rolls a week.
