What goes in the battery passport

Public: anyone who scans the QR code

• Manufacturer’s name, trade name or trademark, postal address and website or email

• Battery category and identification: model and serial or batch number

• Place and date (month and year) of manufacture

• Weight, capacity and chemistry

• Hazardous substances other than mercury, cadmium and lead, and critical raw materials above 0.1%

• Usable extinguishing agent

• Material composition

• Rated capacity; minimum, nominal and maximum voltage; original power capability and its limits

• Expected lifetime in cycles, temperature range, warranty period, round-trip efficiency, internal resistance and C-rate

• Share of renewable content

• The separate collection symbol and, where they apply, the cadmium and lead markings

• The EU declaration of conformity

• How to prevent waste and how the battery is collected and recycled

Later: carbon footprint, recycled content and due diligence

• Carbon footprint: for LMT batteries from 18 August 2028 at the earliest, or 18 months after the Commission’s detailed rules take effect if that is later

• Recycled content documentation: for LMT batteries from 18 August 2033

• Responsible sourcing from the due diligence report: from 18 August 2027, and only for companies with a net turnover of EUR 40 million or more, or part of a group above that. A provisional EU agreement would raise this to EUR 200 million.

The Commission’s guidance of August 2026 confirms that these data points are not filled in from February 2027.

For parties with a legitimate interest

Such as repairers, remanufacturers, second-life operators and recyclers. A draft act published on 19 October 2026 sets out who qualifies, and is open for feedback until 16 November 2026. For the battery model they see:

• Detailed composition, including the materials of the cathode, anode and electrolyte

• Part numbers and sources of spare parts

• Dismantling information: exploded diagrams, disassembly steps, fastenings, tools and the number and layout of cells

• Safety measures

And for the individual battery, which the draft opens to the battery’s buyer and those acting for them:

• Performance values when the battery is placed on the market and whenever its status changes

• State of health

• Status: original, repurposed, re-used, remanufactured or waste

• Usage data, such as charge cycles, negative events like accidents, temperature and state of charge

For authorities

Notified bodies, market surveillance authorities and the European Commission can also see the results of the test reports that prove compliance.

Model data and battery data

Most of the passport describes the battery model and is the same for every battery of that model. The serial number, status, state of health and usage data belong to the individual battery. That is why every battery needs its own passport, not every model.

Where the state of health comes from

Since 18 August 2024, LMT batteries have had to keep up-to-date state-of-health and lifetime data in their battery management system, with read-only access for the buyer and independent operators. That data feeds the state of health in the passport.
