Thanks David! That means the upper limit for continuous operation is in the range of 1-2 hours with the K10D. If used with NR, only half the time is available for exposure.
Great to hear the camera is able to switch battery source in real time. I suspected the opposite from the messages in the display when one battery runs low.
