What If the Battery Passport Record Is Wrong

A battery passport record that is wrong must be corrected under the same unique identifier, with the error, the correction, the date and the evidence preserved, so that a later reader can see what was wrong, what was changed and why. The correction method matters because a silent fix, in which the wrong entry is overwritten without a trace, hides the error and leaves a later reader unable to tell whether the present entry is the original entry or a corrected entry. A correction that creates a new record for the same battery is worse, because it breaks continuity and creates two records for one battery, each claiming to describe it. The correct method preserves the history, including the error, and adds the correction as the next dated entry in the same history.

The scope is correction of errors in Annex XIII records for batteries within Article 77, as checked on 28 October 2026. The guide does not state the market surveillance or enforcement consequences of an error, which need a case specific reading.

What kinds of record error occur?

Record errors divide into identity errors, model errors, individual errors, date errors and access errors. An identity error puts the wrong identifier on a record or the wrong record on a battery. A model error states the wrong model, category, chemistry or capacity. An individual error states the wrong performance, status or use information for that battery. A date error misdates an entry, so that the sequence is wrong. An access error puts information in the wrong tier, so that a reader sees too much or too little. Each kind needs a different correction, because an identity error needs an identity resolution, a model error needs a model correction, and an access error needs a tier correction, and a correction that treats every error as a data entry error will miss the kind that matters.

How is an error found and recorded?

An error is found by comparing the record with the battery, the specification, the documents and the test evidence, in the identity first order, and the finding should be recorded with the date, the finder, the entry in question, the evidence that shows it is wrong, and the correct position as far as it is known. A finding that states only that the record is wrong, without the entry, the evidence and the correct position, cannot be corrected, because the corrector will not know what to change. The finding should be kept with the record file, linked by identifier, so that a later reader can see the error work without repeating it. An error found by a buyer, a repairer or an authority should be recorded in the same form, regardless of who found it.

Who corrects the record, and how?

The record is corrected by the operator responsible for the entry, or by the record holder on the basis of evidence supplied by that operator, with the correction recorded as a dated entry that states the error, the correction, the evidence and the corrector. A later holder who finds an error should notify the responsible operator and the record holder, with the finding record, rather than correcting the record directly, because a direct correction by a holder who does not own the entry creates a second version of the truth. Where the responsible operator cannot be reached, the finding should be recorded as an open correction, with the holder, the date and the notification recorded, so that a later reader can see that the error is known but uncorrected. An open correction is stronger than a silent error.

What does a correction table look like?

A correction table pairs the error kind with the correction method, so that the correction can be chosen without breaking continuity. The table below uses general error kinds.

What should a reader do with a record known to contain an error?

A reader who knows that a record contains an error should read the record with the error and the correction together, should not rely on the erroneous entry, and should record the reliance limit in the reading note. Where the correction is open, the reader should state that the entry is disputed, name the finding, and seek independent evidence for the fact in question, such as a test or an inspection, rather than relying on the disputed entry. A reader who proceeds as if the record were correct, despite knowing of an error, risks a decision based on a fact that the file already shows to be wrong. The reading note should state the error, the correction status and the independent evidence relied on.

How are corrections prevented in future records?

Corrections are prevented in future records by quality checks at record creation, by independent reading of a sample of records, by a gap and error register that is reviewed, and by fixing the method that caused the error, not only the record that contains it. A method that allows an identifier error, for example, needs a duplication check, while a method that allows a date error needs a date sequence check, and each method fix should be recorded with the error that prompted it. Prevention is a method discipline, and a record system that fixes records without fixing methods will correct the same error repeatedly. The error register and the method fix record together show that prevention happened.

What limits apply to correction readings?

The limits are that a correction cannot prove that the corrected entry is accurate, and the corrected entry still needs its own evidence. This guide gives general educational information only and is not individual legal advice. An operator with a specific error should check the Regulation text as checked on 28 October 2026 before acting.
