Thanks. I had some difficulties installing the batteries and was wondering later, if I maybe soldered something incorrectly, hence I would be really glad about a detailed photo.
Back then I also had to wait for the batteries to arrive, that’s when I created this guide. Feel free to upload some additional instructions for the battery changing as well. Btw. the original batteries are connected with (narrow) pins. I bought the same batteries as you intend, but had a tough time to cut the pads to “shape”. I am curious how you will solve the problem.
Btw. did you actually open it and manage to change the batteries? If yes, can you take a photo of the lower side of the IC (the side where there is only a single battery)? Back then I forgot to document that.
