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.
German insurance cards are also EU cards, I have no idea why any country which has cards wouldn’t include the necessary EU stuff on it.
The UK were a reasonable exception as they don’t have insurance cards, you just walk into the doctor’s office they don’t care as long as you’re a human you’re getting treated. And because they didn’t record anything they never got reimbursed when non-UK EU citizens went to the NHS, and then they complained that it’s unfair that they have to reimburse when UK folks get treatment in other countries. You know, complaining about issues they themselves created, typical Brit stuff.
