EU Battery Regulation 2023/1542: Complete Guide

Reviewed 7 November 2026. A guide to Regulation (EU) 2023/1542 for battery manufacturers, energy storage operators, second-life businesses and compliance teams.

Introduction: why the EU Battery Regulation matters

Batteries are central to Europe's transition towards cleaner transport, renewable energy and sustainable industry. But producing and using batteries also creates challenges involving raw materials, emissions, safety, waste and recycling.

The European Union introduced Regulation (EU) 2023/1542 to address these challenges across the entire battery lifecycle.

Unlike rules that focus mainly on battery disposal, this Regulation considers the full journey of a battery — from raw material extraction and manufacturing through to use, repair, repurposing and recycling.

For battery manufacturers, importers, distributors, energy storage businesses and second-life operators, understanding these requirements is increasingly important. This guide explains the seven key areas businesses need to understand.

1. Understanding the scope of EU Battery Regulation 2023/1542

The EU Battery Regulation entered into force on 17 August 2023 and generally began applying on 18 February 2024, with individual obligations following different implementation dates. It replaces the previous Batteries Directive and establishes a more comprehensive regulatory framework.

The Regulation covers five main battery categories:

• Portable batteries: household batteries and portable electronic devices.
• Light means of transport (LMT) batteries: e-bikes, e-scooters and similar vehicles.
• Starting, lighting and ignition (SLI) batteries: conventional vehicle starter batteries.
• Electric vehicle batteries: electric cars, buses and other qualifying road vehicles.
• Industrial batteries: commercial energy storage, backup power and industrial equipment.

The rules generally apply whether batteries are sold separately or incorporated into equipment or vehicles, subject to specific exclusions.

The framework addresses:

• Sustainability and carbon footprint information
• Battery performance, durability and safety
• Restrictions on hazardous substances
• Recycled material requirements
• Responsible sourcing and due diligence
• Labelling and consumer information
• CE marking and conformity assessment
• Waste collection, recycling and material recovery
• Digital battery passports and traceability

The central principle is that battery responsibility extends beyond manufacturing and into the battery's entire lifecycle.

2. Who must comply with the Regulation?

The Regulation affects different organisations depending on their role in bringing batteries into the EU market.

Battery manufacturers

Manufacturers must ensure applicable batteries meet technical, safety, sustainability, documentation and conformity requirements. They are also central to the provision of battery information, including digital battery passports where required.

Importers

Importers bringing batteries into the EU must check that applicable conformity obligations have been satisfied. Importing a battery manufactured outside Europe does not automatically exempt it from EU requirements.

Distributors

Distributors must carry out their applicable checks before making batteries available, including checking required markings and documentation.

Battery operators

Operators of electric vehicle fleets, commercial energy storage and industrial battery systems are not automatically subject to every manufacturer obligation simply because they operate batteries. However, they may need access to technical and lifecycle information for maintenance, warranty management, resale or regulatory purposes.

Second-life battery businesses

Businesses that repurpose or remanufacture batteries can take on additional responsibilities. For example, repurposing an electric vehicle battery for stationary energy storage may require reassessing its characteristics, documenting the changes and creating a linked battery passport.

The important distinction: compliance responsibilities depend on the organisation's legal role, battery category and activity — not simply whether it owns a battery.

3. Sustainability, safety and the circular economy

The EU's battery framework aims to reduce environmental impacts while improving battery quality and making valuable materials recoverable.

Carbon footprint requirements

Article 7 introduces carbon footprint requirements for specified battery categories, with phased implementation and detailed methodologies. These requirements aim to make the emissions associated with producing batteries more transparent.

Relevant information can involve emissions from:

• Raw material acquisition
• Material processing
• Battery manufacturing
• Distribution
• End-of-life treatment

Businesses should collect reliable source information and understand which product categories and implementation stages apply to them.

Performance and durability

Battery performance matters for both sustainability and economics. Longer-lasting batteries can reduce waste and replacement demand. Depending on category, relevant measures include capacity, durability, energy efficiency and performance over repeated charging cycles.

Recycled materials

The Regulation introduces recycled-content documentation and minimum-content requirements in stages. Relevant materials include cobalt, lithium, nickel and lead. Companies should distinguish between declaring recycled content and meeting future minimum recycled-content thresholds.

Repair, reuse and recycling

The Regulation encourages a circular battery economy by addressing removability, replaceability, collection, recycling and material recovery.

For second-life operators, reliable information about a battery's age, condition, operating history and remaining usable capacity becomes commercially important. A battery with credible technical evidence may be easier to evaluate for a second-life application than one with an incomplete history.

4. Due diligence and responsible battery sourcing

Battery production depends on internationally sourced minerals and materials. Some supply chains are associated with environmental damage, unsafe working conditions, human rights risks and limited traceability.

The EU Regulation introduces battery due diligence requirements intended to help covered companies identify, prevent, mitigate and account for relevant adverse impacts. The materials addressed include:

• Cobalt
• Natural graphite
• Lithium
• Nickel

What does responsible sourcing involve?

Depending on applicable obligations, a battery business may need to:

1. Establish a written battery due diligence policy.
2. Identify relevant supply-chain risks.
3. Gather information from suppliers.
4. Assess environmental and human rights risks.
5. Implement risk-management measures.
6. Arrange independent verification and audits where required.
7. Maintain supporting documentation and required disclosures.

Important date change

The EU amended the original Regulation to postpone the application of battery due diligence obligations until 18 August 2027. This was introduced through Regulation (EU) 2025/1561. Businesses should use the revised legislation rather than outdated references to the original 2025 date.

The due diligence rules also include scope limitations and exemptions, so companies should verify whether the obligations apply to their particular organisation.

5. Digital battery passports and traceability

One of the Regulation's most significant changes is the introduction of the digital battery passport.

From 18 February 2027, a digital battery passport is required for newly placed-on-market or put-into-service batteries in these categories:

• Electric vehicle batteries
• Light means of transport batteries
• Industrial batteries with a capacity greater than 2 kWh

The battery passport is an electronic record connected to a specific battery through a digital identifier and QR code.

What information does a battery passport contain?

Depending on the battery category and applicable obligations, the passport can include:

• Battery identity: manufacturer, model, unique identifier.
• Technical characteristics: chemistry, capacity, voltage.
• Sustainability: carbon footprint, recycled content.
• Performance: durability, efficiency and relevant test information.
• Lifecycle: original, repurposed, remanufactured or waste status.
• Operational history: charging cycles, operating conditions and relevant events.
• End of life: dismantling, handling and recycling information.

Not all information is publicly available. The Regulation establishes different information-access categories, including public information and restricted information available to specified authorities or persons with a legitimate interest.

Not every data field is mandatory for every battery from February 2027. Some information depends on the battery type, technical relevance or when its underlying legal obligation becomes applicable.

Why operational battery data matters

A battery passport is not simply a digital certificate. Some of its information relates to how an individual battery performs during use. For example, a battery's:

• Charging and discharging cycles
• State of health
• Operating temperature
• State of charge
• Relevant abnormal events

can provide evidence about its condition and history.

A battery management system (BMS) may provide some of this information, depending on the hardware and available interfaces. Reliable monitoring and recordkeeping can therefore support the accuracy of lifecycle information.

However, monitoring alone does not establish regulatory compliance. Information must still meet the applicable data, verification and access requirements.

What about second-life batteries?

Article 77(7) addresses batteries that have undergone preparation for reuse, repurposing or remanufacturing. Where its requirements apply, a new battery passport must be linked to the original passport or passports.

This is particularly relevant when an electric vehicle battery is repurposed for stationary energy storage. The new responsible economic operator may need to update information that no longer accurately describes the battery.

The European Commission also clarifies that relevant batteries originally placed on the EU market before February 2027 may require a passport when remanufactured after the rules become applicable.

6. Battery labelling, documentation and CE marking

Digital passports are only one part of the regulatory framework. Businesses must also understand physical labelling and conformity requirements.

Labelling

Depending on the battery category and implementation date, requirements can include:

• Battery identification information
• Capacity information
• Separate collection symbols
• Relevant chemical markings
• QR codes
• Other applicable safety and information labels

From 18 February 2027, Article 13(6) provides for QR codes on batteries, although the information made accessible differs by battery category.

Technical documentation

Manufacturers must prepare documentation demonstrating conformity with applicable requirements. Relevant records can include technical specifications, test evidence, assessments and conformity information. The precise documentation required depends on the product and applicable provisions.

CE marking

Where required under the Regulation, CE marking indicates that the manufacturer declares the battery meets applicable EU conformity requirements.

The conformity process includes assessing the battery against the relevant obligations, preparing required documentation and issuing the EU Declaration of Conformity. Some conformity assessment routes involve a notified body.

A battery passport does not replace CE marking or the required conformity assessment. They serve different functions.

7. Integrating battery regulation into ESG and corporate strategy

The EU Battery Regulation is not only a technical compliance exercise. It also influences broader environmental, social and governance decisions.

Environmental strategy

Organisations can use battery data to better understand:

• Product lifespan
• Replacement frequency
• Resource efficiency
• Waste generation
• Battery reuse opportunities
• Relevant environmental performance indicators

Social responsibility

Responsible sourcing policies can help businesses identify and address human rights and labour risks in battery supply chains. This requires evidence and processes rather than unsupported sustainability claims.

Corporate governance

Battery compliance benefits from clear accountability. A business should identify who owns responsibility for:

• Product conformity
• Supplier information
• Battery lifecycle records
• Regulatory reporting
• Data access and security
• Documentation retention
• Regulatory change monitoring

Operational data and regulatory documentation should be managed consistently so that different departments are not working from contradictory records.

Turning compliance into business value

Beyond meeting legal requirements, reliable battery information can help organisations make better decisions. For example, an energy storage operator may use verified battery history to support maintenance decisions, while a second-life business may use credible performance data to assess whether a battery is suitable for reuse.

These benefits depend on the quality and relevance of the available evidence.
