Obtaining precise internal resistance at different SOC levels requires disassembling the battery pack and connecting it to a professional charge-discharge cabinet for several days of cycling tests. This is beyond the scope of non-destructive used car inspections; we only provide real-time estimated internal resistance data based on OBD port readings.

No, it does not. International shipping (especially RoRo) usually takes 30 to 60 days, during which the vehicle is stationary. A dead 12V battery, natural tire pressure loss, and even wiper aging due to temperature differences are all reasonable physical wear during long-distance transport. We strongly recommend that overseas buyers bring a portable jump starter and an air pump when picking up their vehicles at the port.

Heavy-use vehicles often look clean in photos but show specific wear patterns. Here's what to check: 1. Rear sag and suspension: ask for a side-profile photo of the car on level ground. If the rear sits noticeably lower than the front, the rear springs or shocks may be worn from constant heavy loads. Compare with factory ride height specs. 2. Pedal and seat wear: accelerator and brake pedals with polished metal patches, and a driver's seat bolster that is flattened or cracked, indicate high mileage or intensive commercial use — even if the odometer says otherwise. 3. Hitch and tow bar marks: check the rear bumper area in close-up photos for scratches, bolt holes, or a removed tow bar mount. Ask the seller directly whether the car ever towed. 4. Underbody and frame: request underbody photos. Look for bent or scraped crossmembers, fresh undercoating hiding damage, or uneven tire wear across the rear axle. 5. Data check: many ride-hailing cars in China have records in maintenance databases — a professional inspection agency can flag cars with commercial fleet history. If the seller refuses underbody or close-up photos, treat it as a warning sign and consider another vehicle.
