Game camera - battery life
To the comment about rechargeables not being recommended by camera manufacturers, I don't believe that to be the case entirely. Many manufacturers market solar rechargeable add ons for their cameras.
Wow...how many pics would you say you've gotten in that time period? I get a legitimate 11 months out of a set of Duracell or Energizer AA's in my Trophy Cams and Scoutguard and I thought that was impressive (especially here in central MN)
