Introduction
A battery manufacturer selling into the EU today already has one regulatory deadline behind them. EV battery carbon footprint declarations became mandatory on 18 February 2025, and three more requirements converge in 2026 and 2027.
Regulation (EU) 2023/1542 replaced the EU's decades-old Battery Directive with a single, binding framework covering sourcing, manufacturing, labelling and end-of-life handling. Unlike a directive, it applies uniformly across all EU member states without national variation, and it reaches beyond EU-based companies to any manufacturer placing a battery on the EU market.
This article sets out what the Regulation requires, which deadlines are already in force, which have been delayed, and what manufacturers worldwide should prepare for next.
Article Section
What the Battery Regulation Is and Why It Exists?
Regulation (EU) 2023/1542 entered into force on 17 August 2023, repealing Directive 2006/66/EC. It applies to nearly all battery categories placed on the EU market: portable batteries, batteries for light means of transport such as e-bikes and e-scooters, industrial batteries, starting-lighting-ignition batteries used in vehicles, and electric vehicle batteries, with exemptions only for batteries used in military, space or equipment designed to be sent into space.
The Regulation pursues three objectives: strengthening the functioning of the EU internal market for batteries, promoting a circular economy by improving collection and recycling, and reducing the environmental and social impact of batteries across their full life cycle, from raw material extraction through to waste management.
Because it is a regulation rather than a directive, its requirements apply directly and identically across all EU member states, removing the national implementation variation that existed under the previous framework.

How the Battery Regulation Works?
Carbon Footprint Declaration Requirements
Carbon footprint declarations became mandatory for electric vehicle batteries on 18 February 2025, requiring manufacturers to calculate and declare emissions generated across the battery's production process. The same requirement extends to rechargeable industrial batteries with a capacity above 2 kWh from 18 February 2026, meaning manufacturers currently supplying only EV batteries have a second, separate deadline approaching for any industrial battery lines.
Due Diligence Obligations and the 2027 Delay
The Regulation requires economic operators above a turnover threshold to adopt a due diligence policy covering the sourcing, processing and trading of cobalt, natural graphite, lithium and nickel, verified by a notified third-party body. These obligations were originally set to apply from 18 August 2025, but Regulation (EU) 2025/1561 delayed them by two years to 18 August 2027, after roughly half of EU member states had not yet appointed the notifying authorities needed to accredit verification bodies. The Commission's guidelines on due diligence requirements, originally due in February 2025, are now expected by July 2026.
Labelling and Information Requirements
From 2026, batteries and the devices they power must carry readable labels showing capacity, expected lifespan, performance, chemical composition and disposal instructions. From 2027, much of this information must also be available digitally through a QR code, allowing users and recyclers to access up-to-date data beyond what fits on a physical label.
The Digital Battery Passport
A Digital Battery Passport becomes mandatory from 18 February 2027 for electric vehicle batteries, batteries for light means of transport, and industrial batteries above 2 kWh. Accessible through a QR-linked unique identifier, the passport records sourcing, carbon, performance and end-of-life data across the battery's life. The Commission is required to adopt a delegated act by 18 August 2026 setting out access rights and update procedures for the passport system.
Who Must Comply?
The Regulation applies to any manufacturer, importer or authorised representative placing a battery in the EU market, regardless of where the company is headquartered. A manufacturer based outside the EU that exports batteries into the Union carries the same obligations as an EU-based manufacturer once its products reach EU customers.

What Manufacturers Should Do Now?
Start Carbon Footprint Calculations Now for Industrial Batteries
Manufacturers of industrial batteries above 2 kWh have less than a year from this Regulation's February 2026 deadline to establish lifecycle carbon accounting, and the calculation methodology takes time to align with supplier data.
Use the Due Diligence Delay to Build Systems, Not to Wait
The two-year postponement to 2027 exists because notified bodies are not yet ready, not because the underlying supply chain mapping and risk assessment work has become optional. Manufacturers that start this work now will not be scrambling once verification becomes available.
Prepare Battery Passport Data Architecture Ahead of 2027
Since the passport draws on carbon, sourcing and performance data that must already be collected for other requirements, manufacturers can treat passport readiness as a data integration exercise built on existing compliance work rather than a separate project.
Article Section
Conclusion
The EU Battery Regulation replaces a patchwork of national rules with a single framework, and its deadlines are arriving in stages rather than all at once. Carbon footprint rules are already partly in force, due diligence has been pushed to 2027, and the battery passport follows shortly after.
Manufacturers worldwide that treat 2026 and 2027 as a connected compliance cluster, rather than separate deadlines, will be better positioned than those addressing each requirement only as it becomes unavoidable.

Frequently Asked Questions
What is the EU Battery Regulation?
It is Regulation (EU) 2023/1542, a binding EU-wide framework covering nearly all battery categories that replaced the earlier EU Battery Directive from 17 August 2023.
When do carbon footprint declaration requirements apply?
They have applied to EV batteries since 18 February 2025, and extend to industrial batteries above 2 kWh from 18 February 2026.
Has the due diligence deadline been delayed?
Yes, Regulation (EU) 2025/1561 postponed raw material due diligence obligations by two years, to 18 August 2027.
When does the Digital Battery Passport become mandatory?
From 18 February 2027, for EV batteries, light means of transport batteries, and industrial batteries above 2 kWh.
Does the Regulation apply to manufacturers outside the EU?
Yes, any manufacturer, importer or authorised representative placing a battery on the EU market must comply regardless of where the company is based.
