Surely this is easy for an unofficial battery to replicate... You just have a step during installation where you put the new and old batteries face to face briefly so the data lines touch, and the new battery can read the old batteries ID and memorize it?

There were some devices that would let you copy the ID over but they fell out of popularity / couldn't keep up. Just not worth it for a low margin item I guess.
