Buying a Used EV: How to Check Battery Health and Charging Equipment
A used EV can be a great deal, but the battery is the most expensive part. Here's the checklist I'm using when I look at used electric cars.

Key takeaways
- Ask for a battery health report or check the car's estimated full-charge range.
- Check warranty coverage on the battery; many EV batteries carry long federal-minimum warranties.
- Confirm the charge port type and whether the original charging cable is included.
Look at the battery first
Many EVs show an estimated range at 100% charge. Compare it with the original EPA range on FuelEconomy.gov for that year and trim. Some dealers can also print a battery health report.

Check the warranty
Federal rules require EV battery warranties of at least 8 years or 100,000 miles on certain components, and some states require longer. Confirm what's left on the specific car you're buying.
Don't forget the charging gear
Find out whether the mobile charging cable comes with the car and what plug the car uses (J1772 or NACS). Factor a home charger into your budget if one isn't included.
