EU Battery Regulation: deadlines & battery passport timeline (2025–2027)
The EU Battery Regulation (Regulation (EU) 2023/1542) has applied since 18 February 2024. Its carbon-footprint and supply-chain due-diligence obligations phase in via delegated acts — several of which have been delayed — and the digital battery passport becomes mandatory on 18 February 2027 for EV, industrial (>2 kWh) and light-means-of-transport batteries.
Next deadline: 18 February 2027 · 227 days
Deadline timeline
-
Regulation applies · passed
Most provisions of Regulation (EU) 2023/1542 begin to apply, replacing the 2006 Batteries Directive.
Applies to: All batteries placed on the EU market
Source ↗ -
Due-diligence guidelines · passed
Commission to publish operational supply-chain due-diligence guidelines. The binding due-diligence obligations themselves were postponed by roughly two years (see 2027 below).
Applies to: Economic operators above turnover thresholds

Battery passport mandatory
Every EV, industrial (>2 kWh) and light-means-of-transport battery placed on the EU market must carry a digital battery passport, accessible via QR code.
Applies to: EV, industrial and LMT battery manufacturers
Source ↗ -
Supply-chain due diligence
Binding supply-chain due-diligence obligations on critical raw materials apply, following a roughly two-year postponement from the original August 2025 date.
Applies to: Economic operators above turnover thresholds

Who’s in scope
- EV batteries, industrial batteries above 2 kWh, and light-means-of-transport (LMT) batteries — e-bikes, e-scooters
- Portable and SLI (starting, lighting, ignition) batteries for labelling and collection rules
Exclusions
- Batteries in equipment for national security, defence, or space
- Some detailed due-diligence obligations have been proposed for extension to 18 August 2027 — confirm the current applicable date
The EU Battery Regulation replaced the old Batteries Directive and phases obligations in by battery type and size. Most provisions have applied since 18 February 2024, but the carbon-footprint declarations and binding supply-chain due-diligence obligations depend on delegated and implementing acts — several of which have slipped. The carbon-footprint methodology and declaration-format acts for EV batteries (originally due in 2024) were delayed, and the due-diligence obligations were postponed by roughly two years, to 18 August 2027. The date still ahead for most manufacturers is 18 February 2027, when the digital battery passport becomes mandatory for every EV, industrial (>2 kWh), and light-means-of-transport battery placed on the EU market.
The battery passport is a sibling of the ESPR Digital Product Passport — same QR-code delivery, similar typed data structure — and it is the first DPP-style obligation forcing a fully populated, publicly accessible digital passport. The data it must carry includes carbon footprint (kg CO₂e per kWh), recycled-content percentages for cobalt, lithium, nickel, and lead, and supply-chain due-diligence declarations.
The engineering work compounds with the ESPR DPP: the identifier infrastructure, versioned endpoint, and supply-chain data assembled for the battery passport become the foundation for the broader product passports that follow. Note that some detailed due-diligence dates have been subject to proposed extension — confirm the current applicable date for your battery class against the regulation before relying on it.
