Used Electric Car Buying Checklist: 10 Checks Before You Pay

The seller has charged the car to 100%. The cabin looks clean, the test drive is quiet, and the price seems reasonable. What else should you check? This used electric car buying checklist helps you verify the seller’s claims and identify what still needs inspection.

1. Identify the exact car and battery version

Match the VIN, registration details, manufacturing year and variant. Check the battery version too: cars with the same model badge can have different packs and charging specifications. For a used Nexon EV or MG ZS EV, ask for the original invoice or vehicle specification rather than guessing from the badge. If the battery has been replaced, request the replacement paperwork.

2. Get a dated battery health report

If the seller says the battery has “excellent health”, ask to see the evidence. A useful report identifies the car, test date, method and findings. Look for the source of the State of Health, or SOH, figure. Was it read from the battery management system, calculated from a separate test, or simply estimated? Keep a copy you can review later.

3. Find out whether capacity was measured

Ask one direct question: “Did this inspection measure usable battery energy, or read the car's own health estimate?” Both can be useful, but the answer changes what you can conclude. A printout with an SOH percentage should explain how that percentage was obtained. A short scan is not automatically a measured capacity test.

4. Save the diagnostic scan before faults are cleared

Arrange a scan with equipment that supports the vehicle. Ask which systems were accessible and request the original fault record, including status information where available. A stored code needs interpretation. Ask whether it relates to a current problem, previous work or an issue that needs further testing. A clear dashboard after codes are erased does not explain why they were recorded.

5. Watch the car charge

Check the charge port, supplied cable and charging equipment for visible damage. Ask about previous interruptions or failed sessions. Where practical, observe AC charging and, for a compatible car, a DC session. Note the starting SOC and any messages. Charging power varies with the car, charger and battery conditions, so investigate the session rather than judging the car by one peak number.

6. Arrange an external underbody inspection

Have a qualified inspector examine accessible covers, the battery enclosure and surrounding structure. Request photographs of damage or signs of previous work so you can discuss them properly. Keep this to an external inspection. Opening the pack or handling high-voltage components requires appropriate specialist training and procedures.

7. Read the repair history, including battery work

Ask for invoices covering battery repairs, charging complaints, cooling-system work, software changes and accident repairs. If a module or pack was replaced, ask what prompted the work and what checks followed. Documented repair history is far more useful than a verbal assurance that “everything was changed”.

8. Use a test route that resembles your driving

Record distance, starting and finishing SOC, average consumption, AC use and warning messages. Include the kind of roads you expect to use after purchase. A short drive is useful for observing behaviour. It cannot settle every question about capacity. Do not run the battery towards empty to see whether it fails.

9. Verify warranty coverage for the next owner

Use the warranty document applicable to that vehicle and confirm the position with the manufacturer or authorised dealer. Check time and distance limits, transfer requirements, exclusions and the claim process. Record who will complete any ownership-transfer formalities. Avoid relying on warranty advertising for a newer model or another variant.

10. Check whether the car fits your routine and budget

Include tyres, suspension, brakes, insurance and your charging arrangement in the decision. A battery inspection does not replace a full used-car inspection. Think about your usual daily distance and where you can charge. Ask for a written list of immediate work, items to monitor and unresolved findings before agreeing on the price.
