How do I verify a buyer's claim about my EV battery pack's remaining capacity before accepting their offer?
Short answer: Ask whether the buyer's capacity assessment came from an actual diagnostic test on your specific pack or from a general estimate based on the vehicle's age and model, and request the test results directly if available — a buyer who tested your pack should be able to share concrete data, while a generic estimate presented as a specific measurement is worth questioning.
Skip the phone calls. List your EV or lithium battery scrap once and let verified buyers on ScrapTrade come to you with real offers.

Genuine battery capacity assessment involves diagnostic equipment measuring your specific pack’s actual performance, producing concrete data like a capacity percentage or health score. An estimate based purely on vehicle age or mileage, without testing the actual pack, is a rougher approximation that could be significantly off in either direction.
What to ask for
Request the actual test data or report if diagnostic testing was performed — module-level voltage readings, a stated state-of-health percentage, or similar concrete figures. A buyer who genuinely tested the pack should have no issue sharing this.
Getting an independent check
If you have any doubt about a buyer’s capacity claim and the pack is valuable enough to justify it, having an independent diagnostic check done before accepting an offer can confirm whether their assessment lines up with reality.
How ScrapTrade Makes This Easier
Buyers on ScrapTrade who offer to share actual diagnostic data upfront for an EV pack are generally more trustworthy than those quoting a number without backing it up — worth factoring into which offer you accept.
