New EU battery rules taking effect early next year are pushing tech makers toward user-replaceable batteries in products like headphones, e-readers, handheld consoles, laptops, and possibly earbuds. But carve-outs for smartphones and tablets may mean replaceable batteries won't necessarily return to phones in the way many users remember. The Verge's Dominic Preston reports: Since the upcoming law doesn't actually come into force until February 18th, 2027, companies still have plenty of time to get their ducks in a row. Still, it's likely that before then we'll see more and more manufacturers launch products with user-replaceable batteries, across audio, e-readers, gaming handhelds, and more. Only time will tell whether most of those products are EU only, or whether the new European laws shape the nature of tech worldwide. It's likely that some product categories will move slower than others. Tech companies will have breathed a sigh of relief that wearables look likely to be exempt, but if wireless earbuds aren't carved out as well then there may be a scramble to adapt the miniature designs for easy replaceability. "The in-ear form factor demands extreme miniaturization, to fit the driver, antenna, processor, microphones and battery," notes a recent report from consultants Futuresource, going on to suggest that meeting the requirements will make earbuds both bigger and more expensive to manufacture. There also remains uncertainty about how some elements of the law will be interpreted. The law requires that user repairs be possible using "commercially available tools," which are "tools available on the market to all end-users." Right to Repair Europe's Alberico points out that this is a broad definition, likely to include a lot of tools not found in most houses, so there will likely be nothing to stop manufacturers requiring the sorts of less common screws that require dedicated electronics tool kits. There's also no strict definition of the "reasonable" price that manufacturers are required to set for spare parts. "That will likely take time -- and possibly litigation -- to clarify in practice," Alberico says. "But without fair access to affordable spare parts, repair will struggle to become the simplest and most attractive option for consumers." The big disappointment is that the separate phone and tablet legislation means we won't see any real changes there, so long as manufacturers make their batteries and devices durable. "This creates a false tradeoff between durability and repairability," Alberico says. "Robust, waterproof devices should not have to come at the expense of user-replaceable batteries. While the ecodesign legislation requirements meant an improvement in battery durability and replaceability, at Right to Repair Europe we'll continue to advocate for all products to be designed with user-replaceable batteries." Whether the EU will listen remains to be seen. Otherwise, the main product people seem to want to replace the battery in may remain one of the only ones where they can't.Read more of this story at Slashdot.
