Hi Malte, Looks like you¹ve made a fairly detailed study, one which I will have to make myself when the board comes back to me. The patch assigned logic was

As far as battery holders go: There actually are holders with a much smaller rim. They almost fit the holes on the PCB (both old and new). Usually I bend one

Yup! Although I must recap, the part that fits is a CR2032 with tabs on. Lithium leaks would cause an explosion so I don t think this will be an issue. Of
