This file focuses on traction-battery condition. Its approval points are battery identity, diagnostic report, cell balance, with destination and commercial checks kept visible.
Decide traction-battery condition
Separate capacity loss from temporary range prediction. Record temperature, state of charge, recent driving, auxiliary loads and tyre pressure during any road test. Compare energy added at the charger with the change in displayed state of charge, while allowing for charging losses.
Use the section outcome to decide whether battery identity is confirmed or needs another document before the candidate advances.
Evidence for traction-battery condition
The traction-battery condition evidence file should connect Battery identity, Diagnostic report and Cell balance to one VIN and one capture date. Screenshots without that link remain leads, not approval evidence.
Save the supporting file under the candidate VIN and label how it establishes diagnostic report; do not rely on an unreferenced chat image.
Destination test for traction-battery condition
Test traction-battery condition against destination rules for AC/DC test, Underbody condition and local support. Confirm assumptions with the exact year and documents before payment. Ask the shipping line about current documentation and state-of-charge requirements for electrified vehicles.
Record who will confirm ac/dc test and by what date, because unresolved destination assumptions become expensive after loading.
Commercial control for traction-battery condition
Price traction-battery condition with Battery identity, Diagnostic report and Thermal warnings shown separately. Record currency, validity and excluded work so a narrow quote is not mistaken for a low total.
State the accepted result for ac/dc test in the written approval record.
Apply traction-battery condition to a candidate
Run the battery review at a documented ambient temperature and starting state of charge. Photograph warnings before clearing anything, read available diagnostic values, inspect high-voltage connectors and cooling areas, and examine the underside for impact, deformation, corrosion or repair. During charging, record charger type, displayed power over time, energy delivered, interruptions and final state of charge. During a road test, observe power limitation, regeneration, temperature messages and abnormal noise. A single state-of-health percentage can be useful, but only when the diagnostic tool, calculation basis and vehicle identity are known. Contradictory evidence should trigger another test, not an averaged conclusion.
Turn this field method into a dated worksheet and keep it with the candidate record so a later reviewer can reproduce the decision.
Record the approval decision
Approve traction-battery condition only when battery identity, diagnostic report, cell balance are supported by candidate-specific evidence and ac/dc test, underbody condition, thermal warnings have an identified owner. Pause if the seller will not connect the VIN to the vehicle, documents or condition record, or if the destination answer depends only on another market's brochure. Record the precise missing test, quotation line or document. Resolve it before payment or reject the candidate; do not carry an undefined technical or commercial issue into shipping.

Does displayed range prove battery health?
No. Temperature, recent driving and software affect the prediction. Use diagnostic, charge-test, thermal and underside evidence.
What should a charging test record?
Starting state of charge, ambient temperature, power accepted, stability, taper, energy delivered, faults and release operation.
When should battery evidence stop a purchase?
Pause for unexplained isolation, thermal or cell-balance faults, impact damage, water evidence or refusal to provide diagnostic access.
