| br>Anyone with an M-EX board in their D-50/D-550 know where to get a replacement battery? It is a CR2450 coin cell, but the opposite polarity to any modern coin cell I've ever seen. Like an old mercury cell, but it is 3V lithium.
I've been through a lot of datasheets and found nothing. Googling the thread title brings up a couple of posts on other forums, all unanswered. I'll probably just end up replacing the holder with one that will a take a commonly available cell. br> br>
