I'd appreciate it if someone with expertise can comment on why the market shifted to non-replaceable batteries. I know the suspicion that it's for planned obsolescence, but does someone really know?
My impression is that replaceable batteries limit the shapes, materials and engineering that can be used, reducing capacity while increasing weight and size. For example a replaceable battery must be safely handled by end users, shaped and placed so it can be easily removed, and its connection is limited to something quickly and easily utilized.
