Battery — BYD Seal U

The traction battery is the single most expensive component in a BYD Seal U, which is why EV makers standardly cover it with a longer warranty than the rest of the car — BYD states 8 years or 200,000 km for its Blade batteries, whichever comes first.

What's worth knowing about the warranty terms

• Coverage usually kicks in once capacity drops below a set threshold (typically around 70% of original capacity), not for any small dip in range
• Keeping the warranty valid usually requires servicing through the authorized network, or at least documented maintenance
• The warranty transfers to the next owner on a used-car sale, as long as it hasn't been voided

Exact terms are always worth checking in that specific car's documentation — they can vary slightly by market and model year.
