The Batteries Regulation refers to the 2023 European Union law aimed at making batteries in most portable electronic devices user-replaceable by 2027. This regulation is part of the EU’s broader effort to promote sustainability, reduce electronic waste, and empower consumers to extend the lifespan of their devices. It sets strict requirements for battery design, labeling, and end-of-life management, impacting manufacturers, importers, and distributors of electronic products. The regulation also covers responsible sourcing of raw materials, recycling targets, and improved information for consumers. While primarily an environmental measure, it has cybersecurity implications, as easier battery access may affect device integrity and security if not managed properly.
