The short answer
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.
What the regulations say
Who uploads the unique identifier
“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”
How a legal person verifies its identity (where required to be established in the Union)
“where required to be established in the Union, they submit evidence of their identity and of their establishment by means of a qualified electronic seal supported by a qualified certificate for electronic seal, issued by a qualified trust service provider pursuant to Regulation (EU) No 910/2014; or after submitting evidence of their identity and of their establishment by means of a qualified electronic attestation of attributes issued under Union law that enables the identification of the economic operator;”
How a legal person verifies its identity (where not required to be established in the Union)
“where not required to be established in the Union, they submit evidence of their identity and, where applicable, of their establishment by means of a qualified electronic seal supported by a qualified certificate for electronic seal, issued by a qualified trust service provider pursuant to Regulation (EU) No 910/2014, or an electronic attestation of attributes issued under Union law that enables the identification of the economic operator.”
How long the verified status lasts
“Economic operators shall retain the status as verified economic operators until their electronic identification means expire but no longer than three years from the date of verification in accordance with paragraph 1 or 2.”
How to register
“The relevant actor referred to in paragraph 1 shall register a digital product passport either through the secure user interface of the registry as provided for in Article 3, point (a), or through the API as provided for in Article 3, point (b).”

The steps of registration
| Step | Rule | Source |
|---|---|---|
| Who registers | The economic operator that places the battery on the market or puts it into service | Battery Regulation Art. 77(10) |
| What is registered | The battery passport's unique identifier | Battery Regulation Art. 77(10) |
| Verify identity first | A legal person uses a qualified electronic seal (backed by a qualified certificate from a qualified trust service provider) or an electronic attestation of attributes issued under EU law. Which provision applies depends on whether the company is required to be established in the Union | Registry Regulation Art. 4(2) |
| How long verification lasts | Until the electronic identification means expire, three years at most; afterwards no new passport can be registered and no registered data changed unless the company verifies again | Registry Regulation Art. 4(4) |
| How to register | In the registry's web interface, or through the API | Registry Regulation Art. 8(6) |
| A third party acting for you | Where EU law lets a third party act in the registry for the economic operator, that party can register once it has been verified | Registry Regulation Art. 8(2) |

Common mistakes
Can I register a battery passport in the EU registry today?
Not yet. The opening date for batteries is not set. The key dates will say so once it is.
Is an e-seal the same as being registered?
No. The e-seal only verifies the company's identity in the registry. Only after verification can the passport's unique identifier be registered.
Is one registration good for ever?
No. Verified status lasts three years at most, or until the electronic identification means expire if that comes first. After that the company has to verify again before it can register new passports or change registered data (Art. 4(4)).
