Which batteries need a passport
Article 77(1) names three categories: LMT batteries (light means of transport such as e-bikes and e-scooters), industrial batteries with a capacity greater than 2 kWh, and electric vehicle batteries. Portable batteries, SLI batteries and industrial batteries of 2 kWh or less need none, but from the same date they carry the QR code of Article 13(6), which links to their information instead.
What the passport holds, and who sees it
Annex XIII has four parts. Point 1 is public: the label information, material composition, carbon footprint, responsible sourcing, recycled and renewable content, and the performance and durability values of the battery model, its markings, declaration of conformity and waste information. Point 2 (detailed composition, spare parts, dismantling, safety) is for persons with a legitimate interest, notified bodies, market surveillance authorities and the Commission. Point 3 (test reports) is for notified bodies, market surveillance authorities and the Commission only. Point 4 holds the data of each individual battery over its life: state of health, status, cycles and negative events, for persons with a legitimate interest (Article 77(2)).
Who counts as a person with a legitimate interest, and what they may download, share and re-use, is for a Commission implementing act that Article 77(9) required by 18 August 2026. It had not been adopted on 25 October 2026.
QR code, identifier and registry
The QR code links to a unique identifier that the economic operator placing the battery on the market attributes to it, following ISO/IEC 15459 parts 1 to 6 or equivalent (Article 77(3)). The operator uploads that identifier to the digital product passport registry of Regulation (EU) 2024/1781 (Article 77(10)). The data must be based on open standards, machine-readable and transferable without vendor lock-in (Article 77(5)).
Who keeps it up to date
The economic operator placing the battery on the market keeps the information accurate, complete and up to date, and may authorise another operator in writing to act for it (Article 77(4)). A battery prepared for re-use, repurposed or remanufactured gets a new passport linked to the original one, and the duty passes to whoever places it on the market again; once the battery is waste, it passes to the producer, its producer responsibility organisation or the waste management operator (Article 77(7)). The passport ceases to exist after the battery has been recycled (Article 77(8)).
From the checklist to your files
The Battery Regulation document kit writes, for each model that needs a passport, an Annex XIII data sheet as Word, CSV and JSON, quoting the Annex and filled in from what you entered, with every missing value marked TO COMPLETE. It is the record you give your passport provider; the kit does not issue the identifier, the QR code or the hosted passport.
