What this software will and will not say.
Suggestions from a model stay proposals until a person confirms them. The customer remains responsible for the passport.
Extraction and the readiness file reader quote the document or say the value was not found. They do not invent a chemistry, a registration, or a seal.
Exporting a registry file is not a submission. The app never shows a unique registry identifier unless a person types the identifier the Commission actually returned.

Questions every importer asks
When is a battery passport required?
From 18 February 2027, for each LMT battery, each industrial battery above 2 kWh and each electric vehicle battery that is placed on the market or put into service (Regulation (EU) 2023/1542, Art. 77(1)).
What does a battery passport contain?
Four levels of information (Annex XIII): public information about the battery model, model information for people with a legitimate interest and the Commission, test reports for notified bodies and authorities only, and data about the individual battery for people with a legitimate interest. The Commission's guidance lists 71 data points. Not all of them apply to every battery, and some are not due yet.
Does a battery passport belong to a model, a batch or an item?
We read Article 77(1) as one passport for each battery, so we create one per serial number and keep the model data once. For other product groups the Commission sets the level per group, and we keep that as a rule that can change.
Are there recycled-content requirements?
The Regulation introduces recycled-content rules (Article 8), but the Commission's FAQ says they are not required in the passport on 18 February 2027 and follow later. We mark such fields as not yet applicable and do not count them as missing.
Who is responsible for the passport?
The economic operator that places the battery on the market. It may give another operator a written authorisation to act for it (Art. 77(4)). Whether that is you depends on how the battery reaches the Union market. Check it with an adviser.
Do you register the passport in the EU registry?
No. Registering the identifier is the responsible operator's own act, and it needs a verified organisation in the registry. We prepare the submission file and a checklist, and we never send anything for you or show a result the Commission did not return.
How long does a passport stay available?
A battery passport exists until the battery has been recycled (Art. 77(8)), and it stays available when the responsible operator ceases to exist or stops its activity in the Union (Art. 78(e)). Anyone may read the public level free of charge (Art. 78(b)).
Is the readiness score a certification?
No. It is a completeness check of the fields you confirmed against the Commission's list. It does not certify a battery, it is not legal advice, and it registers nothing.
