The battery life on the Reconyx camera is almost magical. I have no clue how many pictures in the last year and a half the camera has snapped but it must be in the 50k range and the batteries are still kicking no problem. I feel like someone is changing the batteries without me knowing because it is unbelievable. I use the Lithium batteries as well. Coupled with great pic quality, trigger speed off the charts, and ease of use....unmatched in my opinion.
