What the term actually covers
Two document families cover a built-in lithium cell in a neck massager. One is the transport test record for shipping the cell by air or sea. The other is a battery-safety document covering the cell or pack in the finished product. They are separate records, issued against separate identifiers, and a transport record for a bare cell does not cover the pack inside a finished unit.
The checklist discipline is to ask for both families by name, to check that each names the exact cell identifier used in the sample, and to confirm which document accompanies the shipment versus which one sits in the technical file.
A third family often sits behind both: the pack drawing. The pack drawing shows how the cell is wired, retained and protected inside the shell, and it is the record that connects a bare-cell document to the finished product. Ask for it separately, because without it a battery-safety document describes a pack nobody can inspect.
The two documents that matter most
The transport family covers the movement of the cell. It should carry the cell identifier, the test summary, the issue date and the identity of the cell maker. The battery-safety family covers the cell or pack in the product. It should carry the same cell identifier plus the pack configuration and the test method.
Ask what happens when the cell maker changes. A new cell identifier means both families must be re-issued, and the change must be visible in the file before the next shipment leaves. A supplier who answers "the old document still works" has not answered the question.
Comparison table
| Document family | What it covers | Key identifier | What to check |
|---|---|---|---|
| Transport record | Cell movement by air or sea | Cell maker and cell ID | Issue date and summary |
| Battery-safety document | Cell or pack in the product | Cell ID and pack config | Method and revision |
| Pack drawing | Pack layout and retention | Pack revision | Matches sample |
| Charging note | Charge limits and cut-off | Firmware or charger ID | Matches sample |
| Traceability | Batch and lot marking | Batch code | Printed on product |
| Cell change | New maker, new identifier | Buyer and supplier | Re-issued families before shipment |
A transport document is not the same as a retail label
Transport record ≠ battery-safety document, and neither is the retail packaging or the listing label. The transport record is for the carrier. The battery-safety document is for the technical file. The labelling on the box and the listing copy carry different information entirely. A buyer who reads one as the others will ship without the right paperwork.
The second boundary is between a bare cell and a finished pack. A record for a bare cell does not describe how the cell is wired, retained or charged inside the shell. Ask for the pack configuration separately.
A third boundary is between the shipping copy and the file copy. The copy that travels with the goods carries the carrier's identifiers; the copy in the file carries the full record. Both should exist, and they should match. Ask which is which before the container is booked.
The third question is the pack drawing's currency. A pack drawing that shows the cell wired in a certain order describes a pack that may no longer exist if the wiring has changed. Ask whether the pack drawing revision matches the sample in hand, and read a mismatch as an open question rather than a discrepancy to be explained later.
A second habit belongs beside the identifiers: the batch trace. The cell identifier tells the buyer which cell maker and which cell type; the batch trace tells the buyer which lot a given unit came from. Both are needed, and neither substitutes for the other. Ask how a unit's lot code is printed and where it sits, because a lot code that is only on the carton cannot be read from the product.
The identifier is the join between every record
Every document family in this checklist is joined by one field: the cell identifier. The transport record names it, the battery-safety document names it, the pack drawing references it and the traceability marking carries it. A buyer who checks each document for that one field catches the mismatch that matters most, because a transport record for a different cell will still look plausible on its own. Ask the supplier to list the identifier on every document and to explain what happens when the cell maker changes. A change of maker is the moment both families must be re-issued, and it is also the moment a file assembled from old documents silently describes a cell nobody shipped.
A second join is the pack revision. The battery-safety document and the pack drawing should name the same pack revision, and the charging note should name the same charger or firmware. A buyer who matches the cell identifier across families but ignores the pack revision can still accept a document that describes an earlier pack. Ask for the pack revision beside the identifier on every line of the matrix.
Questions to ask a supplier
- Which cell identifier is used, and does it appear on both document families?
- Who issued the transport record, and when was it issued?
- Which battery-safety document covers the pack as built, and at what revision?
- What change would trigger a re-issue of either document?
- Which document travels with the shipment and which stays in the file?
A fourth family is often missing from a checklist: the change log. A battery document that is re-issued after a cell change should carry the change, and the buyer should see the re-issue rather than the original. Ask for the change log for each document family, because a re-issued document without a log is indistinguishable from an original.
Common mistakes buyers make
- Accepting a transport record for a different cell identifier. Read the identifier against the sample.
- Reading a bare-cell record as a pack record. Ask for the pack configuration.
- Storing the battery documents with the product files and losing them at shipment. Separate the travelling copy from the file copy.
Each is caught by building the battery document matrix per cell identifier and by naming the owner who updates it after a change.
