I have owned the BG-11 for a few years now and only recently got around to trying out the BGM-E11A "AA" battery pack.
I noticed that the battery info says "BGM-E6" instead of BGM-E11A. ("BGM-E6" is the AA pack for the 5D Mk II)
Is this normal? Does anyone else see the same thing when using the AA pack with a 5D Mk III?
Did you previously own a gripped 5D II and may have grabbed the wrong battery magazine?
I still have my gripped 5D III... so I looked at my AA battery magazine and it is the BGM-E11A and it does fit my grip.
So barring the possibility that you simply picked up the wrong AA battery magazine from a 5D II grip... then I'd say they somehow sent you the wrong battery magazine.
My magazine clearly says BGM-E11A on it, so it is the correct one.
If possible, could you check your 5D3 with AA batteries and confirm what your battery info says. I am thinking it just may be a glitch.
Ok... NOW I see what you mean. When I load it with batteries, insert it into the camera, and navigate to the Battery Info menu, it reports that it is the BGM-E6 (just is your image shows) even though it is really the BGM-E11A.
My guess is the 5D III firmware is probably based on the 5D II firmware (but modified as needed) ... except they failed to update the label on that menu.
