Don't believe it...
I was on a trip to the NWRs in northern CA last week. Thought I'd try out the Lithium AAs to see how many shots I'd get so I loaded them the night before the drive. My first picture the camera had problems. It was like it got set to a 3 sec shutter speed. I double checked everything and all settings were set. Next shutter press, nothing. Got the ERR message.
I did the power off/on bit and tried again. Same exact thing. I tried it 3 times. At this point I thought great, camera dies at the beginning of a week long photo trip. Then I remembered I put in brand new Lithium AAs so I pulled them and put back the D100 battery. Everything worked prefectly from then on for the entire week.
When I got home I tried another set of Lithium AAs (bought from a different store about 100 miles away) just in case I happened to get a bad batch. Same problem. When I put them in the F100 they worked prefectly, just not in the D100 (you know, it's a shame, this is the only time my F100 has been used since getting the D100!).
I've completely given up on AAs for the D100. I had called Nikon about it once. They wouldn't confirm or deny there was a problem. They just said I should send in the camera and MB-D100 and they'd look at it. I never bothered. Fortunately the camera batteries have such an incredible life I don't think I'll really need AAs as a backup.
