Do I need one?
What is a battery passport, and who is responsible for it?
A battery passport is an electronic record that goes with the battery; scan the QR code on the battery to open it. From 18 February 2027, LMT batteries, electric vehicle batteries and industrial batteries above 2 kWh need one to be placed on the EU market. The economic operator that places the battery on the market is responsible for what is in it.
Do I need one?
Does my battery need a battery passport?
From 18 February 2027, three kinds of battery need a battery passport to be sold in the EU: light means of transport (LMT) batteries such as e-bike batteries, electric vehicle batteries, and industrial batteries above 2 kWh, home storage included. Every other battery needs no passport, but must carry a QR code from the same day.

2 kWh, 5 kg and 25 kg: how the three thresholds work
2 kWh decides whether an industrial battery needs a battery passport; 5 kg and 25 kg decide which type a battery is. The regulation says “greater than”: an industrial battery needs a passport only above 2 kWh, not at exactly 2 kWh. An LMT battery weighs 25 kg or less, an L-category vehicle traction battery above 25 kg is an electric vehicle battery, and a portable battery weighs 5 kg or less.
Dates
What to prepare before 18 February 2027
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 to fill in
Which data goes in a battery passport? The table of 92 data points
The platform's battery passport field list has 92 data points, compiled from Annex XIII of the Battery Regulation. Which ones you fill in depends on the battery type: for a stationary battery energy storage system 88 apply, of which 59 are required from February 2027. The table to download gives every data point's Chinese and English name and who can read it.
What to fill in
Public, restricted, authorities only: how the three kinds of information are split
The information in a battery passport comes in three kinds: public information that anyone can read by scanning the QR code; information only for notified bodies, market surveillance authorities and the Commission; and information only for companies with a legitimate interest, such as those that dismantle, repair, remanufacture or recycle. The public page never shows the content of the last two.
QR code and registration
QR code and unique identifier: one code per battery
From 18 February 2027 every battery carries a QR code, including batteries that need no passport. For a battery with a passport, the QR code leads to the passport, which is tied to the unique identifier the economic operator gives that battery; for the other batteries it leads to the label, the declaration of conformity and similar information. The QR code and the unique identifier must follow the ISO/IEC 15459 series or an equivalent.
QR code and registration
How to register in the EU registry, and what about the e-seal
The EU digital product passport registry (the EU registry) cannot take battery passports yet, and the opening date is not set. Once it opens, the economic operator that places the battery on the market uploads the battery's unique identifier. Before that the company has to verify its identity; a legal person does so with a qualified electronic seal or an electronic attestation of attributes issued under EU law. What you can do now is get the documents ready.
Who is responsible
Manufacturer, importer, authorised representative: who does what
The economic operator that places the battery on the EU market answers for the battery passport: it has to keep the information accurate, complete and up to date, and may authorise another operator in writing to act for it. When a Chinese manufacturer is not established in the EU, the company that places the battery on the EU market is usually an EU importer, and the manufacturer can prepare the passport first. If you are unsure who carries the responsibility, ask a professional.
