Buying a used EV in the US: what to check
Battery health, warranty transfer, connector type and the used-EV-specific checks to make before buying a second-hand electric car in the US.
Used electric cars in the US have fallen a long way in price, which makes them excellent value — provided you check the things that decide a used EV's worth. Battery condition and warranty position matter far more than odometer reading.
This guide is a placeholder outline while we finish our full breakdown. The sections below cover what the finished article will explain in detail.
Battery health
Ask for a state-of-health readout or an independent battery test. Hot-climate cars and cars that lived on DC fast charging tend to show more degradation than the average.
- Compare indicated full-charge range against the original EPA figure
- Ask how the car was routinely charged and to what state of charge
- Climate history matters: sustained heat is harder on packs than cold
Warranty transfer
Federal rules require an eight-year or 100,000-mile battery and electric powertrain warranty on new EVs, and some states require longer. These normally transfer to later owners, but capacity thresholds and exclusions vary.
- Confirm remaining battery and powertrain warranty in years and miles
- Check the capacity threshold that triggers a claim
- Check whether any state-extended warranty terms apply
Connectors and charging
Confirm whether the car is NACS or CCS, which adapters are included, and its maximum DC charging rate — older cars can be much slower on a fast charger than current models.
History, recalls and software
Run a history report, check open recalls including battery-related campaigns, and confirm which connected services and over-the-air features transfer to a new owner.
