We tried using rechargeable batteries in our game cameras — eight batteries per camera, and we have three cameras … so it’d be nice not to throw out two dozen double-a batteries. The question, though, was how long they’d last. (Well, the first question is if they’d work at all … nuance of battery chemistry and electric production … the cheap rechargeable AA’s are lower voltage than throw away ones. But we quickly proved that the cameras would run on these batteries). We put the cameras out on October 3, and the cameras are still operational today. That’s over two weeks on a charge. We’ll see when the last videos record, but they’ve already proven to be functional for our purpose.

The first batteries to discharge stopped recording overnight 11/6 to 11/7 … 34 days on a charge. One set was still working, but we pulled them all to discharge / charge them.
