I've found battery life has as much to do with the camera, as with the batteries. I had some that were battery eaters, others that would last a long time. Of course, a lot of it has to with the settings on the camera, and whether or not you're taking videos. I have mostly Moultries, and a Spypoint. The Spypoint is still running on the original Energizers, for over a year now. I prefer Duracell, or Energizer, with Ray-O-Vacs a distant third.
