It had been in the works for a while, but now it has formally been adopted. From the article:
The regulation provides that by 2027 portable batteries incorporated into appliances should be removable and replaceable by the end-user, leaving sufficient time for operators to adapt the design of their products to this requirement.
I respect that there’s a government out there that actually does things good for the individuals. US government would probably allow laws to make it illegal to replace your own batteries even if you knew how to. Or to outlaw making batteries that are compatible with a company’s devices.
