tl;dr: Ahead of EU battery regulations taking effect in February 2027, Nintendo will roll out revised Switch 2 hardware, Joy-Cons, and controllers in Europe starting summer 2026 with user-replaceable batteries, along with battery replacement kits sold via Nintendo Store. Most revisions carry minor weight increases and small battery capacity changes (the Switch 2 Pro Controller drops ~16%). Nintendo will also stop selling original Switch, Switch Lite, and Switch OLED hardware in Europe from mid-February 2027, and several accessories (NES/SNES/Mega Drive controllers, Pokémon GO Plus+) won't get replaceable-battery revisions.
