NEW DELHI: BYD's SEALION 7 warranty documents specify eight years or 1,60,000 km for the traction battery, whichever comes first. The motor and motor controller have the same year limit but a lower 1,50,000 km ceiling. Owners should identify the affected component before assuming that an advertised battery warranty covers a repair.

ComponentPublished warranty, whichever comes first
Traction battery8 years or 1,60,000 km
Motor and motor controller8 years or 1,50,000 km
DC-DC assembly, high-voltage electric control assembly and onboard charger6 years or 1,50,000 km
Listed systems including multimedia and suspension3 years or 1,25,000 km
Bushing or gasket1 year or 20,000 km

The figures above appear in both the standard SEALION 7 booking and warranty PDF and the separate Anniversary Edition PDF hosted in BYD's official assets library. Both documents were read on 29 October 2026. Their shared limits are useful, but the documents should still be matched to the particular vehicle.

The battery name makes a difference

The Anniversary Edition document groups the starting iron battery, identified as LFP (LV), with the motor and controller at eight years or 1,50,000 km. The standard document instead includes the starting iron battery LFP in the remaining-parts category at six years or 1,50,000 km. That is a material difference in the published tables.

This report does not assume that the Anniversary Edition wording retrospectively changes every SEALION 7's cover. An owner presenting a low-voltage battery complaint should ask which warranty document applies to the vehicle and retain that answer with the service paperwork. A model name alone does not resolve the difference between these two documents.

The practical context is specific to this electric SUV: a starting-battery complaint and a traction-battery complaint can both be described casually as a battery problem, yet BYD's tables place them in different categories. Writing the component name on the job card helps avoid an argument based on the wrong headline warranty.

Shorter cover applies to several everyday systems

The standard table places vehicle lights, the tyre-pressure monitoring module, suspension, multimedia system, shock absorbers and charging-port assemblies in the three-year or 1,25,000 km category. An owner cannot determine a touchscreen or charging-port claim solely from the traction battery's longer coverage period.

The same document lists items including brake pads, tyres, wiper blades, bulbs, fuses and air-conditioner filters under no warranty. These are separate entries in the policy. A workshop estimate containing both a covered component and an excluded item therefore needs to be read line by line rather than treated as one indivisible claim.

Consider an illustrative visit involving a multimedia fault and a routine filter change. The useful question is which policy row applies to each job. The presence of an EV battery elsewhere in the vehicle does not establish cover for either item, and this example does not predict how BYD would decide a particular complaint.

For anyone retaining this SUV beyond its initial ownership period, the distinction deserves a permanent place in the service file. A saved policy copy preserves the wording being relied upon when discussing component cover later.

Use the policy supplied with the vehicle

Before discussing a repair, assemble the vehicle's warranty paperwork, registration details, odometer reading and the workshop's description of the fault. This is a practical way to organise the conversation, rather than a claim that the short PDFs prescribe an exhaustive submission checklist.

Keep a copy of the estimate and ask the workshop to identify the warranty category it has used. If the response relies on a distance limit, compare it with the odometer; if it relies on an exclusion, ask for that exclusion to be identified. These steps make a disputed classification easier to examine without promising that a claim will succeed.
