What to know about MG batteries
The catalogue covers 1 MG electric model, on sale since 2022. The packs recorded use NMC or LFP cells, and the difference matters: LFP holds up better over time than nickel, and the gap widens with age.
Battery warranty. The terms recorded for MG range from 7 to 8 years, up to 80,000 to 100,000 miles, with a guaranteed minimum capacity of 70%. These terms depend on the date of first registration, not on the model alone: the checker gives the end date for a specific car.
