I am getting only about 500-600 frames off a single charge with my camera with new batteries that have been refreshed. This is with IS lenses, but only moderate chimping. I know some folks have reported 1200 and more. As I am planning another trip with no possibilities of recharging, I am hoping to find a way to improve this and not need to take my extra batteries. Any ideas? I was considering taking the camera for evaluation to see if there is a problem there.

Depends on the ambient temperature as well as use of IS, chimping, autofocusing etc., but 600 frames sounds about right to me. That's what we're getting this week on a photo trip to Acadia, with outside temps about 70 - 80Ā° F. At times I've gotten as few as 200 frames in cold weather. Manual focus everything, turn off the IS, minimize your chimping and keep batteries warm to eke out the maximum battery life. But by all means, take extra batteries if you'll have no ability to recharge. Otherwise you're guaranteed to see something like an ivory-billed woodpecker landing on a tree 30 feet away ten seconds after your battery goes dead. In the old days the saying was "film is cheap, so shoot it". If you're lugging a 3 lb. camera that costs $8,000 (U.S.) new, it hardly makes sense to leave the spare battery at home.
