Selling your used EV: what your battery report can prove

When you list a used EV for sale, battery health is very often the first question a serious buyer asks — and "it seems fine to me" isn't an answer that closes a deal. An independent, measured report turns your word into evidence, which works in your favour as the seller just as much as it does for the buyer.

Why sellers benefit from a report too

• It pre-empts the battery-health question before a buyer even asks it, speeding up the sale.
• It removes the buyer's biggest source of uncertainty about a used EV, which can reduce lowball offers based on worst-case assumptions about degradation.
• It's independent — a buyer is naturally more likely to trust a third-party measurement than a seller's own description of "barely any degradation."
• It gives you concrete numbers to point to in your listing, rather than vague reassurances.

What to have ready when you list

1. A recent, independent SoH report — ideally generated close to your listing date, since buyers will reasonably wonder about a report that's a year old.
2. Your charging habits, if you can summarise them honestly (e.g., mostly home AC charging, occasional fast charging on trips) — this supports the report's numbers with real context.
3. Any known warranty status — how much of the manufacturer's battery warranty (typically 8 years / 160,000 km) remains on the car.
4. Service and software update history — buyers increasingly ask about this alongside battery health.
5. Basic mechanical documentation — tyres, brakes, and general condition, since battery health is only part of the picture for a used EV buyer.
