A reliable start after a recent boost does not prove the 12-volt battery or sleeping electrical system is healthy.
Define the decision
Confirm the exact battery type, capacity, production date, terminal condition and mounting for the identified engine and market. Inventory start-stop equipment and added dash cameras, trackers, lights or audio hardware. Use the applicable owner information for charging, jump-start and storage procedures. Decide who monitors the vehicle during seller-yard and port storage before it is handed over.
Evidence to collect
After a suitable rest, record open-circuit voltage and a proper battery test, then capture cold cranking, charging voltage or control data, warning messages and a full scan. Check grounds, fuses, splices and cables. If abnormal drain is suspected, a competent technician should measure sleep current only after modules have completed their normal shutdown sequence.
Risk and export exposure
A recently charged weak battery may pass one demonstration. Low voltage can trigger unrelated communication or start-stop faults, while random battery disconnection can disturb learned functions. Unsafe accessory wiring creates drain and fire risk. Long storage, heat and repeated short movements may age a battery without adding much odometer mileage.
Apply it to a candidate
For a Coolray with a tracker and intermittent no-start history, hold approval until the battery is charged, tested and observed through repeated sleep and cold-start cycles. Map the accessory circuit, repeat diagnostics at stable voltage and replace unsafe wiring. Record battery condition at loading and give arrival staff a safe recovery plan. Connect the result to the shipping handover plan and check added devices in the software and connectivity guide.
Build the VIN record
Create a dated folder named by VIN. Record battery identity and age, rest and load test, cold cranking with source documents, photographs, diagnostic output or inspection results. Keep charging behaviour, sleep-current evidence, port storage plan as named actions until the responsible reviewer closes them. A replacement vehicle starts a new file rather than inheriting another candidate's evidence.
Independent review
Assign each field to a reviewer with the relevant competence. Technical, legal, shipping and destination questions should not be answered by one general seller statement. If records conflict, preserve both versions and request the exact document, test or image that resolves the difference before payment.
Commercial hold points
Connect payment to evidence. Confirm identity before reservation, condition before final technical acceptance, contract wording before a major transfer and loading condition before handover. A changed VIN, beneficiary, delivery point or accepted exception reopens the relevant approval gate.
Arrival and ownership control
Freeze the odometer, warning state, keys, accessories, body condition and unresolved exceptions before loading. Compare the arrival vehicle with that record before cleaning or repair. Preserve evidence for claims and give the destination workshop the exact version, service and diagnostic baseline.
Translate uncertainty into a specific next action
For a reliable start after a recent boost does not prove the 12-volt battery or sleeping electrical system is healthy., avoid labels such as “looks fine” or “probably standard.” An open question should request a precise VIN photograph, legal record, diagnostic result, measured value, road-test observation or written destination answer. Assign the request and a deadline. If the missing evidence can change safety, legality or a high-cost repair, do not release payment while it remains open.
Prepare the destination handover
The receiver needs the legal identity, keys, manuals, service evidence, diagnostic baseline, accepted condition and outstanding actions. Include the decisions behind charging behaviour, sleep-current evidence, port storage plan. A workshop that can see the pre-shipment state is less likely to order the wrong part, repeat diagnosis or confuse a transport issue with an earlier defect.
Write the approval result
Finish with pass, hold or reject. A hold must name the missing evidence, owner and deadline. Approval means the buyer understands the remaining limits; it does not turn an unknown into a confirmed feature or remove destination responsibility.
Record the evidence date and the person who reviewed it. If a candidate changes, repeat the affected checks instead of carrying an earlier approval to another VIN, model year or seller.
Check Geely Coolray 12V Battery and Storage Risks: checklist

Use these sources for context only; the candidate remains market-, year-, trim- and VIN-specific.
Official Geely New Coolray model page ↗Buyer questions
Can low voltage cause several Coolray warnings?
Yes. Restore a stable supply and rescan before concluding that several modules failed.
Does low mileage mean the battery is fresh?
No. Calendar age, heat, storage and repeated discharge also matter.
Should accessories be left connected during shipping?
Follow carrier and vehicle requirements and remove or isolate unsafe loads through a competent technician.
