What the screen is built on
Every determination traces to the regulation itself and the Commission's own guidance. These are the primary sources — each linked, with what we use it for and how current it is.
Regulation (EU) 2023/1542 — the Batteries Regulation (EUR-Lex, consolidated)
Used for: the core of every result — the battery categories, the passport requirement and its 18 February 2027 start, the definition of the economic operator, and the phased obligations (carbon footprint, labelling, due diligence). Every scope and responsibility call cites an article here.
Freshness: primary law. We read the EUR-Lex consolidated version so it reflects amendments in force. Re-checked before each material update; last reviewed 9 July 2026.
Amending regulation to 2023/1542 (EUR-Lex)
Used for: catching corrections and adjustments to the original text — including changes to the sequencing of due-diligence and other dated obligations — so the screen reflects the regulation as amended rather than only its first-published form.
Freshness: we track EUR-Lex for amendments to 2023/1542 and fold them into the screen. Where the linked instrument has been superseded, EUR-Lex resolves to the current version. Last reviewed 9 July 2026.
European Commission — Batteries Regulation guidance
Used for: the Commission's own plain-language explanation of the regime, the timeline of obligations, and pointers to the delegated and implementing acts that fill in the detail. We use it to confirm dates and interpretation, not as a substitute for the legal text.
Freshness: Commission pages are updated as the delegated acts land. We check this page for movement on the passport delegated act (due 18 August 2026) and the standardisation work. Last reviewed 9 July 2026.
European Commission — battery passport and Digital Product Passport materials
Used for: context on the battery passport as the EU's first mandatory Digital Product Passport, the QR/identifier direction, and how the data-carrier and access model are expected to work — which informs the passport data inventory we hand you.
Freshness: this is the area still converging. We treat it as a watch item and describe the passport contents as a plan, not a frozen specification, until the delegated act and standards are final. Last reviewed 9 July 2026.
A note on freshness
Two of the things this report depends on are not yet final: the delegated act on the passport's data and access (due 18 August 2026) and the QR/identifier standards. A regulation-dependent figure can change, so we date every report and re-verify the regulation's status before each material update. If a source below has moved since you read this, the EUR-Lex and Commission links resolve to the current version.
