Can I get a Chinese EV battery replaced under warranty?
Updated 2026-05-186 min read
Battery replacement is the ultimate ownership fear. Here's what's actually covered.
01
How claims work
Battery health test at dealer: 2-hour DC charge cycle with SOC/voltage logging.
If capacity <70% (BYD, Zeekr, NIO) → free replacement or refurbishment.
Software-induced degradation: not covered (though rare in practice).
02
Transferability
BYD: transfers to second owner if service history is complete.
MG: transfers, 7-year warranty from first registration.
NIO with BaaS: warranty follows the battery subscription, not the car.
03
Out-of-warranty replacement cost (2026)
BYD Atto 3 60 kWh Blade pack: ~£8,500 including labour.
NIO ET7 100 kWh NCM: ~£14,000.
Zeekr 001 100 kWh Qilin: ~£12,500.
Key takeaways
- 01Warranty covers major degradation within 8yr window.
- 02Transfers with the car — protects used values.
- 03Out-of-warranty replacement is expensive but rare.
