What the source covers
UK MG electric vehicles registered on or after 1 September 2019, encompassing the 2022-2024 MG4.
Quote: MG covers the MG Electric/Hybrid Vehicle lithium ion battery for unlimited mileage up to 12 months, and for 80,000 miles between 13 months and 84 months (whichever comes sooner)... if it is determined that the lithium-ion high voltage battery has suffered a capacity drop below 70% of the original value at delivery... the segment below 70% will be deemed excessive loss.
