For repairers and recyclers
The parts of a passport made for your work.
A battery passport has parts anyone can read and parts the law keeps for readers with a legitimate interest: repairers, remanufacturers, second-life operators and recyclers, for taking the battery apart safely and knowing what is inside it, and the buyer of an individual battery. On a passport served by Odal Node, those parts open with a credential.
This page covers the battery passport, the first one the law requires, from 18 February 2027. For other product groups, no act sets these access rights yet.
What you can read
Open to anyone, and open with a credential.
Without a credential
Point 1: public information about the battery model
Material composition, carbon footprint, recycled content, rated capacity, expected lifetime, declaration of conformity, waste management information.
With a credential
Point 2: model information for readers with a legitimate interest, and the Commission
Detailed composition, part numbers and where to get spare parts, dismantling information, and safety measures.
Point 4: the individual battery's own history
State of health, battery status, and "data resulting from its use, including the number of charging and discharging cycles and negative events, such as accidents, as well as periodically recorded information on the operating environmental conditions, including temperature, and on the state of charge".
Test reports proving compliance are for authorities only, and a battery's own history is for readers with a legitimate interest only: neither group sees everything. Visibility shows the split field by field, and the example passport shows a whole passport sorted this way.
Getting a credential
Two ways to be let in.
From the company behind the product
The company that runs the passport can issue you a credential from its own node, naming your role: repairer, recycler, remanufacturer, preparer for re-use or distributor. It lasts up to 90 days, and you ask for a new one when it ends.
From an issuer the company trusts
A company can also accept credentials from other issuers, such as a trade body, and chooses which ones. Where that issuer publishes a list of withdrawn credentials, the node checks it.
There is no EU-wide issuer of these credentials yet. EU law lets the Commission set out how credentials are issued and checked, and the Batteries Regulation required it to specify, by 18 August 2026, who counts as having a legitimate interest and what they may do with the information. Until the software follows those acts, it applies the Regulation's own wording.
Keep it safe
Treat a credential like a password.
A credential works on its own: anyone holding a copy can use it until it expires or its issuer withdraws it. Keep it inside the business doing the work. A credential issued by a company's own node cannot be withdrawn, which is why it lasts 90 days at most.
After the sale
When the battery changes hands, and when it ends.
Repurposed or remanufactured
Whoever puts a re-used, repurposed or remanufactured battery back on the market takes over the passport duties, and the battery gets a new passport linked to the original.
Waste
Once a battery becomes waste, the duties pass to its producer, the producer's take-back scheme, or the waste operator chosen to handle it.
Recycled
After the battery has been recycled, its passport ceases to exist.
Odal Node records a handover inside the passport: the outgoing company signs it and the node signs its acceptance. It exports the whole record as one signed file anyone can check without a network connection. Lifecycle follows a passport from start to end.
Check it is genuine
Verify a passport yourself.
Every passport served by Odal Node is signed with an identity on the issuing company's own web domain. Drop its proof file into Verify to check the signatures and history in your browser, without Odal.
