Okay guys and gals. My D200 is the best camera in the universe. Everything is great. Including the fact that I can monitor my battery performance. But even in Miami, I noticed my battery life was a bit less than the 1800 shots/charge they claim. And just FYI, my shooting style with the D70 lined up just about perfectly with their battery life figures if not even erring on the side of more shots! Ok I mean a LOT less. I've charged my battery at least 5 times since the first shot. I'm 307 shots in. Almost always using available light or my SB-600. Used the built in maybe 10 times. AF assist light on camera is off. True, I'm using the LCD a bit more than usual, but i've got the brightness turned down to -2, and it doesn't justify the amount of battery drain i'm seeing. My counter right now is at 17 shots, 93% battery remaining. This is minimal image reviewing, and so on. My battery performance up to now has been worse...much worse. 50 shots and down 26%, and the like. The cold weather up here may affect the battery in some ways...but not this much. In fact I had the same battery life in Miami- the first 100 shots or so brought me down almost 50%! I've noticed a few other posts on other forums complaining about poor battery life- maybe we've got a few defective batteries out there? I'm going to write Nikon about this ASAP. I wish i'd had a chance to get spare batts :frown: Anyone else?
