Build a battery passport under the Batteries Regulation

What applies today

The Batteries Regulation (EU) 2023/1542 applies now, and its battery passport (Article 77) applies from 18 February 2027 to light means of transport (LMT) batteries, electric vehicle batteries and industrial batteries with a capacity above 2 kWh. Portable batteries carry no passport obligation: for them the pack records the Annex XIII data as product information only.

Other obligations have their own dates, which the pack follows: the separate-collection marking from 18 August 2025, removability and replaceability information from 18 February 2027, the due-diligence policy from 18 August 2027 for operators above the turnover threshold, and the recycled-content documentation from 18 August 2028. A carbon footprint declaration is recorded only once the delegated act for the battery category applies.

What the pack checks

DPP Shield validates a passport against the bundled EU-BATTERY pack, which is a draft readiness pack, plus the ESPR core checks every category shares: identifiers, the economic operator, the data carrier, substances of concern and passport availability. Required findings block publication; findings to check are flagged for review. Each finding in the console names its rule and source.

Required - blocks publication

• Battery type (portable, LMT, EV, industrial or stationary), chemistry and capacity - the type decides which checks apply.
• Model identifier, batch or serial, place and date of manufacture, weight and nominal voltage.
• Manufacturer name and address, the EU declaration of conformity reference and the waste-prevention and end-of-life information.
• Suitable extinguishing agent, critical raw materials present, and hazardous substances other than mercury, cadmium and lead.
• Rated capacity, the separate-collection symbol among the markings and a QR code carrier.
• Removability: whether the end user or a professional can remove and replace the battery, with the instructions.
• Where they apply: the due-diligence policy, the recycled-content declaration for cobalt, lithium, nickel and lead, and SVHC information with the SCIP number.
• From 18 February 2027, for LMT, electric vehicle and industrial batteries: renewable content, original power capability and its limits, the cycle-life reference test and its C-rate, the storage temperature range and its test, round-trip efficiency at 50 % of cycle life, cell and pack resistance, the six Article 74 waste information items, the restricted model data (detailed composition, part numbers and spare-part contacts, dismantling, safety measures), the test reports for authorities and the battery's status. Electric vehicle batteries also need their capacity threshold for exhaustion.

What it flags for review

These do not block publication, but resolve each one before the passport goes public.

Check - flagged for review

• Round-trip efficiency, expected lifetime in cycles and the operating temperature range.
• State of health - dynamic data for the restricted group, not for the public view.
• Replacement instructions for user-removable batteries.
• Third-party verification of the due-diligence policy and publication of its report.
• Recycled shares between 0 and 100 %, and evidence for any voluntary recycled-content claim.
• A UK responsible person, only if you place the battery on the UK market.
• The commercial warranty period where one is offered, dismantling warnings, and the charge and discharge cycle count once the battery is in use.

Evidence to collect

Attach these in Documents and link them to the passport, or request them from suppliers.

Typical evidence

• EU declaration of conformity, and the test reports behind the performance figures (kept restricted).
• Cell and material supplier declarations for chemistry, critical raw materials and hazardous substances.
• Dismantling information - exploded diagram, disassembly sequence, tools - and safety instructions for repairers and recyclers.
• Due-diligence policy, its third-party verification and the published report.
• Recycled-content declarations and chain-of-custody certificates.

Build the passport step by step

1. Create the product with the category Battery - in Products, by CSV import or from a connected store.
2. Open DPPs and choose Create passport: the form shows the battery fields together with the shared blocks (identifiers, manufacturer, materials, substances of concern, data carrier and passport availability).
3. Set the battery type first: it decides which checks apply.
4. Keep part numbers, test reports, dismantling and state-of-health data in their restricted fields; they are withheld from the public page and readable through access grants.
5. If you declare a carbon footprint, fill the carbon footprint declaration - methodology, life-cycle boundary, functional unit, verification - so the public page shows how the figure was produced.
6. Print or apply the QR code from Labels; leave the carrier link empty unless your own resolver serves it.
7. Attach the evidence in Documents and send supplier requests for anything you cannot support yourself.
8. Run Validate EU and work through the findings until no required finding is left.
9. Preview the public page, redact commercially sensitive fields, then publish.

Before you publish

Because the bundled packs are drafts, publishing needs an accountable override approved by a second owner or administrator until your platform operator activates a legally reviewed pack. The readiness score is not a legal assessment: confirm the obligations that apply to your product with your compliance adviser.

Battery data is layered: public information on the passport page, information for persons with a legitimate interest - such as state of health for the battery's owner - and information for authorities. DPP Shield models these layers with redaction and access grants: give repairers, recyclers and second-life operators a grant of the matching tier instead of publishing their data.
