Received my battery today, bought from the link pvdas posted. It came totally unlabeled (not as the picture). It took me a while to even understand what it was. I thought it was some lsd backlight or something.
Anyway, I disassembled my M92 and removed the original battery, just to realize the new one is not identical. It has a smaller connector and the battery itself is a little narrower. I have sent a question to the seller. We'll see if/how he replies.
Until further notice, I would not recommend buying this battery.
