Battery condition is the single biggest value factor in a used EV, and it can be measured — do not accept a verbal "battery is fine" without data. First, ask for a battery health certificate: brands like BYD, NIO, XPeng and Li Auto can generate an official state-of-health report from the VIN, usually within minutes at a dealer or via the brand's app. Look for SOH above 85% for a car under five years old. Second, request a charge-and-discharge test during inspection: the displayed range at 100% charge compared with the original rated range gives a practical health estimate. Third, check battery warranty status. Most Chinese brands offer 8 years or 150,000–200,000 km on the battery pack, and the remaining warranty usually transfers with the car — get this in writing. Fourth, for cars heading to hot climates, confirm the battery cooling system works; overheating is a common killer of battery life. Add a minimum SOH guarantee to your purchase contract so you have recourse if the battery underperforms.

We will provide extremely accurate production year, first registration date, and Chinese emission standards (e.g., National VI). However, the final responsibility for confirming whether this data complies with the importing country's regulations lies with the buyer, and you need to submit it to the local customs for verification before placing an order.

As rubber seals age, "slight oil seepage (oil stains but no dripping)" is very common in used cars and is not considered a major fault. Our recommendation is: as long as the oil level does not drop abnormally, just clean and monitor it regularly after arrival, without the need to immediately incur high costs to disassemble and replace the seals.
