State of Health (SOH) tells you how much of the original battery capacity remains. Here's how to use it. Reading the report: SOH is usually shown as a percentage of original capacity. A car at 90% SOH retains roughly 90% of its original range. Also check for cell imbalance (voltage spread between modules)—a low SOH with balanced cells is often fine, but high imbalance causes sudden range drops and charging problems. Acceptable thresholds: for a car under 3 years old, expect 90%+ SOH. For 3-5 years, 85-90% is normal. Below 80% SOH, the battery may soon need replacement—replacement costs can exceed the car's value, so negotiate hard or walk away. How to verify: don't trust a screenshot. Ask for a live screen recording of the diagnostic app (like the brand's official tool) starting from the car's VIN page. Cross-check the fast-charging curve: a healthy battery charges at near-peak rate up to 60-70%; a degraded one tapers early. Finally, remember that hot climates degrade batteries faster—if the car spent its life in southern China, scrutinize SOH more carefully.

Typically you will need: 1. The commercial invoice and packing list from the seller; 2. The bill of lading issued by the shipping line; 3. The vehicle's export customs declaration; 4. The original registration certificate and a deregistration or transfer proof from China; 5. A certificate of origin if your country requires it; 6. Destination-specific documents, such as a pre-shipment inspection certificate (for example ECTN for West African ports). Requirements vary by country, so confirm the full list with your customs broker before shipment.

You can watch the car through live streaming or VR, or entrust a local third-party agency to inspect the car for you. Transparency about the car's condition is the foundation of trust.
