What deadline applies for updating existing Battery Act registrations?

Companies already registered with Stiftung EAR under the previous Battery Act must update their registration by 15 January 2026 to meet the new requirements of the EU Battery Regulation. This particularly affects information on battery categories and assignment to extended obligations added by the regulation. Whilst the registration number itself remains unchanged, the substantive update is mandatory and should not be postponed to the last moment. Companies that miss this update risk their existing registration being deemed incomplete — with the same consequences as a missing initial registration, including potential fines.
