I just called the shop to replace the perfectly fine e-Call battery in my soon four year old Hyundai car. 250€ to change a battery that has a ten year lifespan. I am not allowed to replace it on my own as it would invalidate the five year long guarantee provided by the manufacturer (not the one by law). Why is this stuff not considered as well?

Also curious whether the "specialized devices" exemptions are AND requirements. Even if those are AND, wouldn’t smartphone manufacturers try to satisfy all three of them?
