I just got a brand new D810 with the MBD-12 battery pack. I was shooting with it the last three days and it's been great. Today the batteries in the battery pack died. I was using AA batteries because the Nikon battery I ordered hasn't come yet, this is where the fun began. When the batteries in the pack die it suppose to go to the camera battery which I think it did. The camera was still shooting but, all of a sudden I would take a picture and on the back of the camera it said "Image cannot be displayed" I took another on with the same result but the previous image was there for review. The I would get the "ERR" message every so often. the camera stopped and I would hit the shutter release button, the shutter would go off, and then back to normal. Finally the camera would just freeze, so I would turn the button to off but the camera stayed on. I would have to take the battery out to reset the camera. Finally it dawned on me to remove the battery pack, which I did and everything now seems normal.Any ideas of WTF is going on. I'm thinking of returning the camera, I have only had it for five days.
