Any vehicle with unresolved traffic violations (fines/demerits) cannot complete the deregistration process at the traffic management bureau, and therefore cannot obtain a legal export license.

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.
