The short answer
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.
What the regulation says
Information anyone can read
“information accessible to the general public in accordance with point 1 of Annex XIII;”
Information only for notified bodies, authorities and the Commission
“information accessible only to notified bodies, market surveillance authorities and the Commission in accordance with points 2 and 3 of Annex XIII; and”
Information only for people with a legitimate interest
“information accessible only to any natural or legal person with a legitimate interest in accessing and processing that information for the purposes referred to in points (a) and (b) of the third subparagraph in accordance with points 2 and 4 of Annex XIII.”
What counts as a legitimate interest
“concern dismantling of the battery, including safety measures to be taken during the dismantling, and the detailed composition of the battery model and be essential to allow repairers, remanufacturers, second-life operators and recyclers to conduct their respective economic activities in accordance with this Regulation; or”
Quotes are from the English text of the regulations; the text published in the Official Journal prevails.
The three kinds, and how many data points each has
The numbers come from the platform's field list, 92 data points in all.
| Kind | Who can read it | Data points |
|---|---|---|
| Public information | Anyone, by scanning the QR code on the battery | 62 |
| Information for notified bodies, market surveillance authorities and the Commission | Only these three; it cannot be granted to other companies | 5 |
| Information for companies with a legitimate interest | Status and usage data of the individual battery, dismantling information and detailed composition, part numbers and spare parts, and safety measures, each with its own readers | 25 |
Who counts as having a legitimate interest is for the Commission to specify in an implementing act, together with how far they may download, share, publish and re-use the information (Art. 77(9)). Who may read each single data point is in the “Who can read it” column of the table of data points.
Common mistakes
Can a scan of the QR code show dismantling information and the detailed composition?
No. The public page shows public information only. Restricted information such as dismantling information, detailed composition and usage data of the individual battery is for the parties entitled by law, after they sign in, according to their rights.
Does restricted mean nobody can read it?
No. The regulation says who may: notified bodies, market surveillance authorities and the Commission; companies with a legitimate interest that need the information to dismantle, repair, remanufacture or recycle; and the purchaser of the battery or parties acting on the purchaser's behalf, in order to make the battery available to independent energy aggregators or energy market participants.
Would it be easier to put all the data on the public page?
It would not be allowed. Restricted information on the public page is information for everyone, which does not follow the split of access rights in the regulation. The platform filters by access right on the server, and the page source of the public page does not contain the restricted values either.
Are the detailed rules on who reads which restricted information settled?
Not yet. The Commission is preparing an implementing regulation under Art. 77(9) of the Battery Regulation that sets who may read which restricted information and what they may do with it. The draft was opened for comments in October 2026 and is planned for adoption in January 2027. This guide follows the current text of the Battery Regulation; while the act is a draft, its final text is what will count, and we will update this guide once it is published.
