Replacing rechargeable batteries in Oticon More

As I didn’t have any batteries, I went to my audiologist. While Oticon literature indeed says that the batteries should be replaced by the audiologist, I was surprised to hear that the audiologist needed to enter the batteries IDs in the system for the HAs to work with the new batteries. Does this make any sense? Can’t the user replace the rechargeable batteries by himself?
