Buying a used electric car: battery health, range, and red flags

An EV's battery is most of its value. Ask for a battery health report: many cars show state of health in a service menu, and shops or apps can pull it from the diagnostic port. A battery at 88% health is normal for a five-year-old EV; 75% deserves a much lower price.

Compare the displayed full-charge range against the original EPA rating. Charge it to 100% before the test drive if possible, and ask the seller how they charged: mostly home charging to 80% is gentle, daily DC fast charging to 100% is not.

Most EV batteries carry an 8-year, 100,000-mile warranty that usually transfers to the next owner, but the terms vary. Confirm the in-service date, what counts as a failure (often below 70% capacity), and whether this specific car still qualifies.

Run the VIN through the manufacturer's recall lookup. Several popular EVs have had battery recalls; a completed recall with a replaced pack can actually make a used EV a better buy than average.

Used EVs depreciate faster than gas cars, which makes them strong value buys if the battery checks out. Factor in your charging situation: home charging makes ownership cheap, while relying on public fast charging changes the math.

Skip the oil change history questions and ask instead about tires (EVs wear them faster), brake condition (usually excellent thanks to regen), software updates, and whether the original mobile charging cable is included.
