battery capacity FORD MUSTANG MACH-E 2021 Warranty Guide

High Voltage Lithium-Ion Battery Capacity Coverage
As is the case with all batteries, the high voltage lithium-ion battery
capacity will decrease over time and with use. While gradual capacity
loss with time and use is considered normal wear and tear, Ford Motor
Company warrants the high voltage battery against excessive capacity
loss for a period of 8 years/100,000 miles, whichever comes first. If an
authorized EV Certified Ford Dealer determines that the battery capacity
is less than 70 percent of the high voltage battery’s beginning of life
capacity, or less than 65 percent for vehicles in cutaway or chassis cab
configuration, this level of capacity loss is considered excessive. The
measurement method used to determine the high voltage battery
capacity, and the decision of whether to repair, replace, or provide
reconditioned or remanufactured parts, and the condition of any such
replaced, reconditioned or remanufactured parts, are at the sole
discretion of Ford Motor Company. During the High Voltage Battery
Capacity Coverage period, Ford Motor Company will cover the necessary
component repair or replacement to correct this excessive capacity loss,
when performed by an EV Certified Ford dealership. This coverage is in
addition to the high voltage battery assembly’s limited warranty for
defects in materials or workmanship. If a warranty repair requires
replacement of the high voltage battery assembly, or one of its
components, it may be replaced with a new, factory remanufactured, or
factory refurbished component, at Ford’s discretion. Refurbished battery
components selected for your vehicle will align with your vehicle’s age,
and mileage.
NOTE: The battery capacity degradation rate will vary based on various
factors, including environmental conditions, and will also be affected by
the way in which the vehicle is used. Following the recommendations in
thePreserving Your High Voltage Battery section of the Owner’s
Manual may help lower the rate of capacity degradation and optimize
battery life.
