SOH (State of Health) measures the battery's remaining capacity as a percentage of its original capacity. Two EVs with the same mileage can have very different SOH depending on charging habits and climate exposure, and since the battery represents 30-50% of a used EV's value, the SOH number is effectively the real price tag. A proper certificate includes current SOH percentage, cell voltage balance, charge cycle counts, battery management system fault codes, and often a projected range estimate. In hot-climate markets like the Gulf, a degraded battery degrades even faster, so a documented SOH above 85-90% is strongly recommended. Exporters who provide verified SOH certificates close deals faster and command better prices, so treat the certificate as a core purchase document, not an extra.

All our measuring instruments (especially calipers, paint thickness gauges, and refrigerant pressure gauges) are calibrated quarterly according to ISO quality management system requirements to ensure the data we provide you is objective, accurate, and reliable.

It must be stated objectively: used cars in China are produced according to national standards (GB) and have not been originally certified by Saudi SASO or GSO of Gulf countries. Buyers must find a local agent with customs clearance capabilities to complete the clearance through exemption documents or compliant modifications after arrival (such as wrapping or adding specific alarms).
