One thing I've found with the *ist D and 20D is that when the battery indicator shows half-full (half the battery icon is shaded), you're done. Replace the batteries ASAP or risk dealing with the previously mentioned malfunctions. In my view there is no "low battery" warning on these cameras. Just an indicator to "CHANGE THE BATTERY NOW!!!"
Same here with the *ist D. Also sometimes those same 'low' batteries, taken out and put back in, will subsequently show as full. When a battery is low, it most often results in the shutter not firing, and then the camera not turning on.
