The short answer
Work out which battery type each model is, gather the spec sheets and test reports, complete the passport data and pass the checks, decide which company places the batteries on the EU market as the economic operator, then publish the passport and print the QR code on the battery. Once the EU registry opens for batteries, the passport's identifier also has to be registered.
What the regulation says
The passport is due from 18 February 2027
“From 18 February 2027 each LMT battery, each industrial battery with a capacity greater than 2 kWh and each electric vehicle battery placed on the market or put into service shall have an electronic record (‘battery passport’).”
The QR code is due the same day
“From 18 February 2027, all batteries shall be marked with a QR code as described in Part C of Annex VI.”
The unique identifier goes into the EU registry
“The economic operator placing the battery on the market or putting it into service shall upload the unique identifier in the registry referred to in Article 13(1) of Regulation (EU) 2024/1781 of the European Parliament and of the Council”

Six things, in order
| Step | What to do | Notes |
|---|---|---|
| 1 | Work out the battery type of each model | The type decides whether a passport is needed and how many data points. Does my battery need a battery passport? |
| 2 | Gather documents | Spec sheets, test reports, safety data sheets (SDS) and so on. Some data only cell and material suppliers have, so ask early. |
| 3 | Complete the passport data and pass the checks | Which data points apply depends on the battery type. Which data goes in the passport |
| 4 | Decide who places the battery on the EU market | An EU importer or your own company. That company is the economic operator and answers for the content; an authorised representative only acts within its written mandate. Who does what |
| 5 | Publish the passport and print the QR code on the battery | Each battery gets a unique identifier and a QR code. QR code and unique identifier |
| 6 | Register the passport identifier once the EU registry opens | The opening date is not set; get the documents ready now. How to register in the EU registry |
How long one model takes depends on how complete your documents are and how fast suppliers deliver data; we do not print a number of days we cannot back up. All the dates are on the key dates page.
Common mistakes
Is it fine to wait until the EU registry opens?
Do not wait. The registry is needed only to register the identifier, but the passport data and the QR code are due from 18 February 2027. The Commission has published its guidance on battery passport data points (version 3.2, 19 October 2026); the battery semantic catalogue the EU registry will use to check passport content has not been published yet. The platform's field list follows the regulation, this guidance and the data model.
If my battery needs no passport, is there nothing to prepare?
There is the QR code. From 18 February 2027 every battery carries one (Art. 13(6)).
Can I not start until all documents are in?
You can start now. Work out the battery type, sort the documents you have, and ask suppliers for what is missing.
