A used electric car is priced like a used petrol car — mileage, age, condition — and that misses the four things that actually decide what it will be like to own. None of them are visible on a forecourt, all four can be checked in an afternoon, and each one has a number behind it. Here they are, with what our own database of 15 US-market cars shows for each.
1. What has already been recalled on that model
Recalls are not a mark against a car; they are a mark against a fault that the manufacturer has agreed to fix for free. What matters for a used buyer is whether the fix was actually done. Across the 35 US-market cars with a verified NHTSA record in our database the count runs from 0 to 10 campaigns, 120 in total — Hyundai Ioniq 5 84 kWh RWD carries the most, and four carry none: Toyota bZ4X, Honda Prologue, Cadillac Optiq and Mercedes-Benz CLA 250+ (the CLA is a 2027 model with little time on the road).
The count is not the point. The open-or-closed status on the specific car is. Every US car has a VIN, and the federal recall database will tell you in seconds whether anything on that VIN is unrepaired: nhtsa.gov/recalls, VIN lookup, free. A seller who has not run it is telling you something about how the car was maintained.
Which EV recalls can be closed with a download and which need a workshop is a separate question, and we counted that too: 147 EV recalls, only 20 of them fixed over the air.
2. Which chemistry the pack uses
Two different chemistries are sold under the same badge, and they want opposite treatment. Of the cars here, Ford Mustang Mach-E Standard Range RWD use LFP cells; the rest use a nickel-based chemistry. An LFP pack is meant to be charged to 100 per cent regularly — the manufacturer asks for it, because the cell needs a full charge to keep the state-of-charge reading honest. A nickel pack is happier kept between about 20 and 80 per cent for daily use.
This matters second-hand in a way it does not when new: you are buying the consequences of someone else’s habits. Ask what they charged to, and on what. The full argument, with the manufacturer guidance for each chemistry, is in should you charge an EV to 100%, and what the chemistries do differently is in LFP vs NMC vs solid-state.
3. The socket it was built with
The connector on a used car is the one it left the factory with, and the transition is mid-flight: of the cars here, 9 are recorded with a NACS port in the US market and 4 with CCS1 (we have not sourced the US port for 2 of them, and those rows stay blank rather than guess). Neither is a wrong answer, but each implies an adapter for part of the network, and adapters are brand-specific and not always included with the car.
Before you agree a price, find the two or three chargers you would actually use and check what plug they have. We counted the whole country by connector, state by state: which plug US fast chargers actually have. If the car comes with an adapter, get it in writing on the invoice — it is the single most commonly missing accessory on a used EV.
4. The range it has, not the range on the window sticker
Every used EV listing quotes the EPA figure, because that is the number printed on the car. Observed real-world range is a different number, measured a different way, and the two are worth seeing side by side before you agree a price. We deliberately do not express one as a percentage of the other: the EPA rating comes from the US test procedure and the observed figure from European road testing, so a ratio would blend a difference in test cycle with a difference in real conditions and present the result as if it were one thing. Read the two columns as two measurements, not as a conversion — why the cycles do not convert explains the rest.
| Car | EPA range | Observed real range |
|---|---|---|
| Toyota bZ4X AWD 73.1 kWh | 288 mi | 233 mi |
| Tesla Model Y Long Range AWD | 327 mi | 283 mi |
| Volvo EX30 Single Motor Extended Range | 261 mi | 227 mi |
| Kia EV6 84 kWh RWD | 319 mi | 280 mi |
| Hyundai Ioniq 5 84 kWh RWD | 318 mi | 280 mi |
| Hyundai Ioniq 6 Long Range RWD | 342 mi | 308 mi |
| Ford Mustang Mach-E Standard Range RWD | 260 mi | 236 mi |
| Nissan Ariya e-4ORCE 87 kWh | 272 mi | 250 mi |
| Ford Mustang Mach-E Extended Range RWD | 320 mi | 295 mi |
| Volkswagen ID.4 Pro | 291 mi | 277 mi |
| Kia EV9 99.8 kWh AWD | 283 mi | 270 mi |
| BMW i4 eDrive40 | 333 mi | 326 mi |
| Tesla Model 3 Long Range AWD | 346 mi | 345 mi |
| Porsche Taycan (rear-wheel drive) | 274 mi | 308 mi |
Then subtract again for the pack in front of you, which is older than the one those figures were measured on. That is the number to plan around, and how quickly packs lose capacity in practice is in what 22,700 real cars show. On the test drive, the honest measurement is not the guess-o-meter at the top of the screen: it is the energy figure. Reset the trip meter, drive thirty miles of the roads you actually use, and read the kWh per 100 miles. Compare it with the EPA figure on the model page for that car and you have a degradation estimate that no listing can argue with.
5. What is left of the battery warranty, on that VIN
Battery cover is the part of a used EV’s value that is easiest to check and most often assumed. Terms differ by manufacturer, by market and sometimes by model year, and they run from the date the car was first put into service rather than the date you buy it — so the only number that means anything is the one for that specific VIN. Ask the selling dealer to print the remaining coverage, or call the manufacturer’s customer line with the VIN before you agree a price. Two further points people miss: most battery warranties carry a capacity floor as well as a defect clause, and a pack that has faded steadily may still sit above the floor and not be a warranty claim at all.
We publish the battery-warranty terms we have sourced on each car’s own page rather than as a single table here, because a table invites you to trust it for a car whose paperwork you have not seen.

What none of this tells you
Nothing above is a substitute for an inspection. A used EV still has tyres, brakes, suspension and bodywork, and it still has an accident history — and on a car with instant torque and two tonnes of kerb weight, tyres are a larger running cost than most buyers expect. These five checks are the ones specific to the electric part; run them alongside the ordinary ones, not instead of them.
What the car will cost you to run once it is yours depends on your electricity tariff more than on the car: put your own rate into the running-cost calculator, or read what home charging costs in your state in EV charging cost by state.
Frequently asked questions
How do I check if a used EV has an open recall?
Run the VIN through the free federal lookup at nhtsa.gov/recalls. It reports campaigns that are still unrepaired on that specific vehicle, not just campaigns issued for the model.
Is a used LFP electric car better than a nickel one?
Neither is better; they want different habits. LFP tolerates and expects regular charging to 100 per cent, nickel chemistries prefer a daily window below that. What matters second-hand is that the previous owner treated the pack the way its chemistry asks.
Can I tell battery health on a test drive?
Approximately, and that is enough to negotiate with. Reset the trip computer, drive a route you know, and compare the car’s kWh per 100 miles against the EPA figure for that model. A large, consistent gap on a warm day is worth a full battery health report before you buy.
Does the battery warranty transfer to me?
Usually yes for the defect cover, and the clock runs from the car’s in-service date rather than your purchase date — but the terms vary by manufacturer and market, and some benefits are limited to the original owner. Check the remaining cover against the VIN before you agree a price rather than after.
