Earlier quoted context omitted.
The final law just makes replacing batteries more accessible (i.e. no glue or special screws), but it doesn't mandate battery packs. Also some devices like hearing aids are exempt. I question whether battery packs would be a good thing to bring back now. USB power banks have 100% interchangeability among many device classes, which is something that not even dry cell batteries achieved. I can choose to leave the house…
Agree - I read this as it will be easy to replace the battery when it reaches its end of life and no longer can hold my charge. It will still take time to replace it, but that's okay since it'll only be done once every few years. It's not meant to re-introduce swappable battery packs, so you won't be able to carry spares on long trips etc.
Or when phone manufacturers realise they may as well do so, at least on some models, because why not. And yes, the battery compartment can be waterproof with a rubber seal... but even so? Many would prefer battery swap to full waterproof, if that was the cost.
