sorry, mignon is the battery size as we call it in germany. It is 13mm in diameter and about 49mm high cylindrical battery, I don't know but I think you call that "AA". If you don't understand what I mean (f... languages...), I'll send some photos to your private address.

The "two battery- trick" is useful, if there IS something you need in the memory. It is easy: you connect a second battery in parallel, replace the first, load it, and then remove the second again. But, in your case, there is nothing in the memory, so you don't need to use that trick.
If you have doubts about the polarity: Negative is close to C1 (a little yellow Capacitor) and if you are looking for +, look for the printed "1984", there is a point near the "8", leading to R1 and D2, this is a nice + for you.
Have fun
Michael
