Problems with AA Alkaline batteries in the MB-D100
To any D100 owners who have yet to try AA Alkaline batteries in their camera via the MB-D100:
Only once, out of curiosity, did I try AA batteries in the MB-D100. I got a few shots off, then the camera would fire, the mirror would lock up, and I'd get "Err". Normally after a few seconds I'd press the shutter button again and the camera would reset. Eventually I noticed that the battery icon was dropping to low or empty each time. I switched back to the EN-EL3 battery and all was well again. I can only conclude that there is either a voltage or current supply issue with the AA batteries. I used fresh alkaline batteries. I don't know what the results would be with NiMH rechargeables or Lithium AAs.
I have given up on using AA Alkalines in the MB-D100. Nikon specifically states that these are acceptable in the instructions, but IMHO they are obviously wrong.

This info was previously posted in a reply and to Victor Newman whose re-intro appears above, I strongly encourage all of you who can duplicate this problem to phone, email and if neccessary scream at Nikon, I was very disturbed at their initial denials.
I just purchased a D100 and the MBD100. I walked into a serious problem using any battery type in the cheap soft plastic battery holder.
Problem: I running the EN lithium in the MBD100, no problem. I remove it (go thru turn off and turn on)and load in the battery tray with 6 new AA alkalines, read 9 VDC at the holder terminals for the AA's and plug it in. Upon turn on, battery icon in the control panel is full. As soon as I autofocus or shoot a frame, the battery icon shows empty and an Err meassage pops up next to the icon. I cant shoot or autofocus, the camera appears frozen just like a computer crash. I remove the AA holder, replace the En lithium and upon turn the battery icon is still empty and Err message still present. If I now try to shoot a frame, the frame is shot and the bat icon shows full and the Err message disappears (microprocessor probably reboots and clears the Op Sys). The voltage across the AA holder is still 9VDC. This charming behavior repeats with NiCd and MnH batteries freshly charged. I went back to the dealer and repeated this failure test on my salesmen's personal D100/MBD100 and the stores inventory of 2 more units, interchanging the battery hold did not alter the results.
The battery holder shares the neg terminal with the EN lithiums-they are the same tab--but the right hand (pos) terminal for the bat holder is seperate, I believe this terminal is not making proper contact or in the case where some of you are actually using AA's and experiencing very short life, that terminal is intermittent or the path thru the camera body is. I emailed Nikon Support(?) a complete report and got back a one line form memo telling me to call Customer Support. After much difficulty trying to communicate between phone support and email support, Nikon admitted that they have a problem and I should be patient. I would appreciate it if those of who have not tried using AA's please do and post your results and if needed also to Nikon. Use the basic AA alkalines, Nikon states no support or reccomendation for use of the MnH or NiCD AA's.
Response to those comments about NiCd, MnH and Alkalines. The alkalines and lithium AA's are 1.5 VDC, the NiCd and MnH are ~1.2 VDC.
AA MnH are available in 1.5 and now 1.8 A-H capacities, 6 in series gives somewhat greater than 7.2 VDC (my freshly charged were 8.1). AA NiCd's are available at 1 A-H and 6 of them give somewhat more than 7.2 VDC. The En lithium is only 7.4 VDC and has a 1.4 A-H capacity, this is less than the MnH's; I believe the discharge curve for the EN and the MnH's should be similar, I have not checked this out yet. If this is so and Nikon fixes this problem we should get comparable performance, both chemistries and construction yield low source impedance batteries, surge currents( think flash/strobe) should not be a problem.
I'm quite certain Nikon is using a switch mode power supply to generate a fixed camera system voltage, such a supply properly design will perform as the battery voltage sags to its discharge value and its impedance increases which will exacerbate the situation.
One more requested comment, how many of you are comfortable swapping the memory card in and out? In my D100 I get scared, I have to carefully rock the card as I get to the bottom--if not I get resistance requiring more force-then I stop and start again. I dont think the guidance tolerance is tight enough to maintain safe alignment. Secondly, this type of pin connector is not designed for multiple insertions, the pin diameters are only 10-12 mils, for PCMIA where the insertion is infrequent or only once it is fine. There are submin connectors using ribbon blades that wipe (like your Printer connector)which will satisfy this requirement. Better to have a self cleaning sliding/wiping action than a head on collision.
I'm brand new to the Nikonians and have been using Nikons for the past 50 yrs. I'm very glad to have found this discussion session, especially at this time.
Thank you all Irving Weiner

You really shouldn't be having problems swapping memory cards. The Compact Flash specification states the connectors should withstand a minimum of 10,000 connect/disconnect cycles, so they should certainly be able to withstand the kind of use they'll get in a digital camera.
It is normal to have to apply some pressure to get the card to go fully home, and my D100 definitely requires a firmer push than my D1.
From your description it sounds as if your camera may have either a badly made or damaged socket: it may be worth getting it checked by your dealer or a Nikon service centre.
