Before exporting a used electric vehicle, ask for a battery health check that reports the State of Health (SOH), explains how it was measured, and includes dated supporting evidence. SOH is useful for comparing a battery’s current condition with a reference condition, but it is not a guarantee of driving range or future service life. We recommend checking the diagnostic report against the vehicle identification number (VIN), odometer reading, battery specifications, and any available fault or repair records. If the seller cannot explain the result or provide evidence you can verify, treat the battery condition as uncertain and resolve that uncertainty before shipment.
You can find more information on our web, so please take a look.
State of Health is a diagnostic estimate of a battery’s condition relative to a defined reference, commonly expressed as a percentage. Depending on the vehicle and diagnostic method, the value may be calculated or estimated from battery management system data, available capacity, or other measurements. The report should identify the source of the figure rather than presenting a percentage without context. Different tools or methods can produce results that are not directly comparable.
SOH should not be treated as a direct promise of real-world range. Range also depends on vehicle model, battery temperature, speed, terrain, weather, tire condition, driving style, and accessory use. A dashboard range estimate is therefore not a substitute for a battery diagnostic report. A buyer should use SOH as one part of a wider assessment, not as the sole basis for accepting a vehicle.
For example, if a vehicle had a stated original usable capacity of 72 kWh and a reliable assessment estimated 82% of that reference, a simple indicative calculation would be about 59 kWh. This is an illustration, not a test result, and it assumes that the figures use compatible definitions. Confirm whether the listed capacity is gross or usable and whether the SOH report refers to the same baseline. A percentage without those details can create a misleading comparison.
Buyers sometimes use 80% SOH as a screening point, but it is not a universal export acceptance standard. The appropriate threshold depends on the vehicle, intended market, price, warranty position, and buyer’s use case. A fleet buyer planning predictable daily routes may set a different requirement from a buyer seeking a lower-cost vehicle for shorter journeys. Put the agreed threshold and any remedy for a result below it in the purchase terms.
Ask the seller to provide documents that connect the reported battery condition to the specific vehicle being purchased. At a minimum, request the VIN, odometer reading in km, inspection date, diagnostic source, and the full SOH result with any stated limitations. A screenshot may help, but a complete report is more useful when it identifies the vehicle and shows the relevant battery data. Make sure the document is legible and that the VIN matches the vehicle and sales paperwork.
Evidence has a time context: a report describes a vehicle at the time it was checked, not necessarily at the time it arrives. As a buyer, you can set a freshness requirement in your order—for example, asking for the inspection to be completed within 30 days before dispatch. This is a procurement condition, not a universal technical rule. If the vehicle is driven, repaired, or stored for an extended period after inspection, ask whether a new check is appropriate.

Specific questions make it easier to compare vehicles and identify gaps before payment or shipping. Request written answers so they can be reviewed alongside the inspection documents. If the seller cannot answer a technical question, ask who performed the check and whether the diagnostic provider can clarify the method. Avoid relying on verbal assurances such as “the battery is good” without supporting records.
Start by comparing the VIN on the diagnostic report with the VIN on the vehicle and sales documents. Check the model, variant, odometer reading, and inspection date for consistency. A report without a clear vehicle identifier is difficult to rely on for an individual purchase. Record any discrepancy and ask for corrected evidence before proceeding.
Read the full report rather than focusing only on the headline percentage. Note any battery, charging, or powertrain fault codes, and ask whether they are current, historical, or cleared after repair. Compare the SOH with service and repair information where available. If records conflict or the report does not explain the result, request clarification or an independent assessment.
Document the required evidence, any minimum SOH or other inspection criteria, and the process for handling a mismatch. Specify whether a second inspection is allowed and when it must occur. Clarify responsibility for inspection, repair, cancellation, or price adjustment before the vehicle is loaded. These terms are more useful when agreed in writing than when discussed only after a problem appears.
A dependable used-vehicle supplier should be willing to discuss what evidence is available, explain the limits of an inspection, and help resolve document or vehicle-identity questions before dispatch. At Nanling Auto, we encourage buyers to define their battery requirements early and assess the supporting records as part of the vehicle selection process. Availability of particular diagnostic documents can depend on the vehicle and its service history, so confirm what can be provided for each unit before placing an order. For fleet or multi-vehicle purchases, agree on a consistent inspection and reporting format to make comparisons easier.
Before you commit, send the supplier your destination market, preferred vehicle models, intended use, required SOH or inspection criteria, and documentation needs. Ask for the available report and confirm in writing how any missing evidence or failed criterion will be handled. The practical answer is to export only after the SOH result is traceable, the evidence matches the vehicle, and acceptance terms are clear. Contact Nanling Auto to discuss used EV sourcing and the battery-health documentation you need for your purchase.
