Short answer
The Battery Regulation itself is a single European text that applies directly in every Member State; there is therefore no separate Dutch, German or French version of the rules. But that does not automatically mean that the practical implementation is identical everywhere. In product regulation, it is customary for the content of mandatory information to be laid down EU-wide, while the language in which that information must reach the end-user may differ from one Member State to another. Whether and exactly how this applies to the battery passport is something you should best enquire about with the competent supervisory authority in the country where you place the battery on the market, or with a lawyer who reads the text for your situation.
For a company that only sells in the Netherlands, this is usually a straightforward question. As soon as you also supply to Germany, Belgium or other Member States, it becomes more interesting: the same battery, the same passport, but possibly a different expectation about the language in which certain data must be readable for the user who scans the QR code.
What is already established at European level
The Regulation determines which data belong in the passport and that those data are accessed via a QR code on the battery. That part of the setup does not change from country to country: an importer in Rotterdam and an importer in Antwerp work from the same basis. the knowledge base with explanations per subject shows per concept what is established at European level and what is still filled in per country, always with the source in the official text.
The point is that the uniformity of the rules at EU level does not automatically mean that every detail of implementation is identical. This is often the case with European regulations: the core is the same, the way a Member State organises supervision or sets requirements on language and legibility can differ.
Where countries may have room for manoeuvre
With comparable product regulations, such as instructions for use or safety information, it is repeatedly the case that Member States may determine that information for the consumer must be available in the national language, even if the underlying standard is European. Whether and in what form this also applies to the battery passport is not stated in this article as an established fact, precisely because that can differ from situation to situation and because the implementing rules for the passport are still being developed. What you can determine with certainty is which countries are relevant for your own assortment, and that is a good starting point for the question you then put to a lawyer or supervisor.
The same applies to the way supervision is organised: authorities in different Member States may have slightly different expectations about how quickly information must be made available or how a complaint is handled, even if the underlying obligation is identical.
What this means if you sell in multiple countries
If your company places batteries or products containing batteries on the market in multiple EU countries, it is advisable to map out in advance which Member States are involved and to check per country whether there are additional requirements for language, packaging or labelling beyond what is already in the Regulation. This prevents you from having to make separate adjustments per country afterwards to something you had already set up.
For companies that are unsure whether their situation affects multiple countries, or that want to see where their own assortment stands on this point, the product scan that provides an initial indication in a few questions is a practical first step. The result is not a legal opinion, but a direction to continue searching in.
Where you can enquire about this yourself
Because language requirements and the precise implementation can differ per Member State, and because implementing rules on the battery passport have not yet crystallised in every respect, this is typically a question for the competent supervisory authority in the country of supply or for a lawyer who places the official text alongside your assortment. the frequently asked questions about the passport in practice provide an overview of similar questions that other companies have already asked, each with a reference to the source text.
If you want to understand how we merge data from the official text and from manufacturers or importers into a passport, and why that traceability always remains transparent, you can read about it on the page about how the information is created.
In short
The core of the battery regulation is European and does not change from country to country. The way in which language, supervision and practical implementation are carried out can differ per Member State, and that is precisely why enquiry with the supervisory authority or a lawyer remains worthwhile as soon as you operate in multiple countries.
