NEW DELHI: MG Windsor EV's lifetime battery warranty for a first private owner is tied to the validity of the vehicle's first registration certificate. MG's published warranty booklet says a change of ownership brings an eight-year or 1,60,000 km limit, whichever comes earlier, counted from delivery to the first owner. That makes the registration history essential paperwork when assessing a used Windsor.
| Windsor warranty item | Published condition |
|---|---|
| First private owner's traction battery | Through validity of first registration certificate |
| Battery after ownership change | 8 years or 1,60,000 km from first delivery, whichever earlier |
| Commercial battery | 8 years or 1,00,000 km, whichever earlier |
| Complete vehicle, personal registration | 3 years, unlimited kilometres, excluding wear parts |
Start with the car's documents
A prospective second owner should put the original delivery invoice beside the registration certificate before discussing remaining cover. The date on a resale advertisement is no substitute for the first delivery date. Ask for the complete ownership chain as well, especially where a vehicle has moved through an intermediary. The useful question is how much eligible cover remains on this particular car.
MG's product page describes the Windsor as a five-seat CUV and lists both 38 kWh and 52.9 kWh battery choices. Its FAQ advertises lifetime battery cover for the first owner and specifically confirms that promise for Exclusive Pro. The more detailed booklet supplies the registration and transfer conditions behind that shorter product-page description.
Those two sources serve different purposes. A model page helps identify the vehicle and its advertised benefits; the warranty document explains how a claim is considered. Save the booklet applicable to the car alongside its invoice. If a seller supplies only a screenshot of the headline promise, request the underlying terms before treating it as evidence of transferable protection.
Separate the battery from the rest of the Windsor
It is helpful to draw up separate records for the traction battery, the complete vehicle and any additional package purchased with it. Do not use the longest advertised period as the expiry date for everything. A cabin fault and a battery concern can fall under different entries even though both appear on the same workshop job card.
The Windsor's cabin equipment makes that distinction practical. MG lists a large central display, connected functions and reclining Aero-Lounge rear seats on its product material. An owner comparing long-term costs should keep the equipment fitted to their trim in view. Battery protection alone cannot answer every question about maintaining an electronically equipped family car.
For context on the wider MG electric range, see the desk's Comet EV price report. Keep service paperwork with the warranty file so a workshop can see what was inspected and when. A clear record is more useful than trying to reconstruct the car's history after a warning appears. Include the original sale paperwork, workshop invoices and any written clarification of the warranty supplied during a later ownership transfer.
Prepare a concern for inspection
If you suspect a battery issue, document what happened in ordinary language: the warning displayed, whether the car was driving or charging, and whether the behaviour repeated. Photograph the instrument display while safely parked. Avoid turning an estimated range reading into a diagnosis. A workshop needs a reproducible symptom and vehicle history to investigate the concern.
Ask the service adviser to record the complaint accurately and provide the inspection outcome in writing. Keep any estimate, diagnostic explanation and proposed remedy together. This is a practical recordkeeping approach, rather than a guarantee that a particular complaint qualifies. Eligibility depends on the applicable terms and the workshop's findings.
A used-car handover deserves the same care. Request a written statement of remaining cover linked to the vehicle identification details, registration status and first delivery record. A verbal assurance that the Windsor has lifetime protection leaves the transfer condition unresolved. The seller's understanding and the manufacturer's recorded position should agree before the handover is treated as complete.
Read battery rental separately
Windsor buyers also encounter Battery-as-a-Service material. Keep the battery finance or rental agreement separate from the warranty booklet when reviewing ownership costs. A payment arrangement answers who pays and under what contract; warranty terms answer a different set of questions about eligible faults and remedies. Request both documents if the vehicle was supplied under such an arrangement.
The existing Windsor price report and Indulge and Pro comparison cover the model's purchase choices. For warranty paperwork, begin with the actual Windsor being assessed, then reconcile its registration, delivery and ownership records with the written cover.
