I'm with doubleA, I have three moultrie cameras and three feeders. I bought rechargable batteries and solar chargers. It costs a little more up front, but In the last 10 days my cameras took about 1800 pics. That would have been a load of regular batteries. Plus I would have missed some of the pics because of a dead battery ( s ) . I checked the cameras this afternoon and all three batteries were fully charged, and like I said, I got about 1800 pics.

It is the only way to go.
