MINI USA, a division of BMW of North America, LLC warrants the high-voltage lithium-ion battery assembly against defects in materials or workmanship for a period of 8 years / 100,000 miles for EVs and 8 years/80,000 miles for PHEVs, whichever occurs first. Due to its inherent technical design, the high-voltage lithium-ion battery’s capacity will decrease over time and with use. If an authorized MINI dealer's capacity check concludes that the net battery capacity is less than 70 percent of its original nominal value when it was new, this level of capacity loss is considered excessive. During the High-Voltage Lithium-Ion Battery Capacity Coverage period, MINI USA will cover the necessary component repair or replacement to correct this excessive capacity loss when performed by an authorized MINI dealer.
