Hello, from my research I gather changing the internal coin battery on these "requires factory service", which is EOL. Regardless of being soldered in or whatever I would like to at least look at it to satisfy my curiosity, maybe attempt something with copper tape or the like for patching in a fresh battery. Does anyone know where it is located to help in which side of the camera to start dismantling?
I have 3 of these with one no longer holding settings between external battery swaps so worth it to me to give it a go.
Anyone ever done this, or gone inside for another reason and seen the battery set up?
