Under Regulation (EU) 2023/1542 a portable battery is a battery that is sealed, weighs 5 kg or less, is not designed exclusively for industrial use, and is neither an EV, LMT, nor SLI battery — the typical batteries in consumer electronics and household devices. Portable batteries are not subject to the Article 77 battery passport requirement, but they are covered by other obligations such as removability and replaceability rules, collection targets, and labelling.
