I've used Energizer rechargeable D size batteries and C size batteries as well as the AA's. With the D and C size it depends on the camera. They lasted less than a week in our Cuddeback and about a week or two in the Bushnell, and Wildview cameras and they seemed to last longer in the Leaf River cameras. For some reason the rechargeables do not outperform the alkalines in these battery sizes and cameras.

On the other hand as you mentioned it is exactly opposite with the AA's.
