I've noticed occasional discussion on D70 battery life. It seems to be the belief that battery life is less when the camera is used with VR lenses. I was at an airshow on Saturday evening and took 1135 shots in a 2 and a quarter hour period. I was using a 70-200 VR with TC-17e and VR on throughout the event. Not only did one battery last the whole evening, but I haven't recharged it since and there is still life in it. I am impressed.
