Batteries placed on the EU market from 18 August 2026 must carry labels covering capacity, chemistry, and hazardous substance markings, and the burden lands hardest on manufacturers with fragmented supplier data. Missing or inaccurate labelling is not a cosmetic issue: it blocks market access, invites enforcement exposure, and forces costly rework once products are already in distribution.
