Used EV Checklist

Used EV Proof Checklist

A used EV with a degraded battery or missing warranty can cost $8,000+ to fix. These 10 checks take under an hour and protect you from the biggest risks.

Know your fit before you buy

Check if an EV matches your commute and charging situation — before you fall in love with a listing.

Check Battery State of Health

Use OBD2 + app (LeafSpy for Leaf, BatteryView for others) or request a dealership report. Above 85% SOH is acceptable; below 75% is a red flag.

Test DC Fast Charging Speed

Take it to a DCFC station. If a car rated for 100 kW peaks at 50 kW, the battery or charging hardware has degraded.

Run a VIN Check for Open Recalls

NHTSA.gov shows open recalls by VIN. Many older EVs (Bolt, Leaf, Hyundai/Kia) have had battery-related recalls — verify they're closed.

Request Charging History

Many EVs log charging events. Frequent DCFC sessions (especially >80%) accelerate degradation. Ask what the primary charging method was.

Check OTA Software Version

Verify the car has the latest software. Major updates can affect range, efficiency, and charging behavior. Outdated software = outdated performance.

Confirm Battery Warranty Remaining

Federal law mandates 8 years / 100K miles for the battery. Calculate from the original purchase date (not odometer) to know what's covered.

Inspect 12V Auxiliary Battery

EVs have a small 12V battery that powers accessories. Failure strands you even if the main pack is full. If it's original on a 4+ year old car, budget for replacement.

Check Regen Braking Strength

Test one-pedal driving at low speed. Weak or inconsistent regen can indicate battery or inverter issues.

Frequently Asked Questions

How do I check battery health without tools?▾

Ask the seller to show you the battery health screen in the car's settings (most modern EVs display this). For third-party verification, a pre-purchase inspection at a dealership or EV-certified shop costs $100-150.

What battery health percentage should I require?▾

For a primary vehicle, look for 85%+ SOH. For a secondary or urban-only car, 80%+ is workable. Below 75% means significantly reduced range and you should negotiate the price accordingly or walk away.

Do I need a mechanic for a used EV inspection?▾

A standard mechanic can inspect the body, suspension, and 12V system. For battery and charging system checks, use an EV-certified technician or the dealership for that brand.
