Battery Grade Labels: What Evidence Should a Buyer Request?

Ask the seller to define the label in writing, then request the document that would support that definition for the exact SKU and batch. “Original,” “OEM,” “premium” and “A+” are sales terms unless a document ties them to something checkable. None of the transport or commercial rules cited in this article sets those words as a grade, so one seller’s “OEM” may not match another’s. Treat each label as a claim with three states: documented, stated by the seller only, or unconfirmed.

Why the wording matters in a B2B purchase

A written definition protects both sides. In New York’s Uniform Commercial Code, a description of goods that becomes part of the basis of the bargain creates an express warranty that the goods will conform to it, and a sample or model can do the same for the whole of the goods (UCC 2-313). Federal trademark law separately addresses false or misleading descriptions and misrepresentations about the nature or qualities of goods in commercial advertising (15 U.S.C. 1125(a)). Disclaimers and governing law can change how these rules apply to your order, so read the seller’s terms too.

For a repair shop, the immediate effect is practical. If the quote says “OEM” without defining it, comparing the delivery with the agreed description becomes harder. Ask for the manufacturer, condition and supporting evidence so you can describe the part accurately to your customer.

Label, evidence and what stays unconfirmed

Sales label	Evidence to request	What it still does not prove
Original or genuine	Written definition, purchase chain to the device maker or its authorized channel, and label images	Identity of the specific units, unless the chain reaches that batch
OEM	Name of the claimed manufacturer, what relationship the seller means, and part number on the unit	Authorization by the device brand. Factory identity alone does not show it
Pulled, used or take-off	Source of the parts, the seller’s screening record, and return terms	Remaining life. It also does not settle whether the device will show a status message
Premium, A+, AAA	Seller’s written grade criteria, what is measured and the failure allowance	Comparability with another seller’s grade name
High capacity	Specification sheet, watt-hour rating on the case, and the basis of any capacity claim	Real capacity on your units, unless a dated test covers that batch
New or zero cycle	Manufacture date or batch code, condition definition, and how cycle status was determined	Storage history, or accuracy of a health reading on an unverified battery
UN 38.3 tested	Test summary matching the battery type and manufacturer	Grade, device compatibility or brand authorization
UL or other certified	Certificate or file number, then a check on the certifier’s own database	Coverage of this model, unless the record names it

Reading the evidence you receive

Device-maker status messages

For iPhone, Apple’s own status screen is informative, but it is narrower than it looks. Apple says an Unknown message can appear when a battery is not genuine, is not functioning as expected, has not been verified and linked after repair, or has been modified or cannot be verified. A separate Used message can appear on iPhone 15 and later with iOS 18 (Apple: About genuine iPhone batteries). In Parts and Service History, a Genuine result means the repair used genuine Apple parts and processes (Apple: iPhone Parts and Service History).

Because the process counts along with the part, a single message does not grade a whole batch. An Unknown result on a sample raises a question for the seller, while a seller’s label cannot override the device’s message. Apple also says battery health information might not be accurate on an unverified battery, so a health percentage is weak evidence for a “new” claim on such a unit.

Test summaries

Each manufacturer and subsequent distributor covered by the federal rule must make a UN 38.3 test summary available. Required elements include the testing laboratory, a unique test report identifier, the list of tests with results, and a responsible person’s name and title (49 CFR 173.185(a)(3)). Check that the battery description matches the part being sold. Then treat it as what it is: a transport-testing record for a battery type. It should not appear on a quote as proof of “premium” quality.

Third-party certification marks

UL’s Product iQ lets buyers verify certification by keyword, category code or file number, and UL describes its Recognized Component Mark as covering assessment for use within a larger certified product, under defined conditions of acceptability (UL Solutions: Components). If a record cannot be found, UL lists several explanations, including a discontinued certification, a very recent one, a manufacturer’s self-declaration, or certification by another third party (UL Solutions: Code Authority FAQs). Ask the seller which applies. If the certification is very recent, UL says the manufacturer should be able to supply documentation from UL.

Samples

A sample only helps if you can link it to the delivery. Ask whether it comes from the same manufacturer and batch you will receive, and keep the sample’s label photos with the quote.

Questions to send with a quote

How do you define [label] for this SKU, in one or two sentences?
Who manufactured the battery, and who supplied it to you?
Which document supports that statement, and does it cover this batch?
Is the part new, used or otherwise processed? How do you determine that?
What should we expect to see on the listed device models after installation?
What is your failure allowance, and what is the remedy if the label proves inaccurate?

Record the answer in three columns

Claim on the quote	Documented (file name)	Seller statement only	Unconfirmed
Example, fictional: “Premium”	Grade sheet, version 2	Consistent batches	Cell manufacturer
Your claim
Your claim

An unconfirmed cell is not automatically a reason to reject a quote. It shows what you are accepting, and it stops your shop from repeating a claim to customers that you cannot support. Describe the part in your own paperwork only as far as your evidence reaches.

Next step

Take your last battery quote and put every descriptive word through the table above. MRG Platform quotes are specific to each request, so ask for any label to be defined for that request, with its supporting documents, before you commit.
