in a residential area I can get 50 or more pics a night with does fawns coyotes coons etc over bait.....usually change at 30 days with or without low bat indicator, however, it can go much longer with fewer pictures
I always date them with a magic marker because I can't remember which ones I put in each camera at different times
buy them at Costco.....much cheaper, especially on coupon....my recycle bin is unbelievable this time of year....
and just for the record, my Capture IR (in my opinion) never lasted...same experience with a buddy.....dumped it and stuck with flash....unless you are trying to capture criminals stealing your tools, I like the quality of flash over IR
