The Mustang Mach-E is expected to run 300,000-500,000 miles before the cells in its lithium-ion battery pack need replacing.
If lithium-ion batteries were to decline 20.3% after one decade of ownership,
then a 10-year-old Ford Mustang Mach-E will be at 197 miles per battery charge.
With average prices far in excess of $100/kWh, lithium-ion battery packs such as those found in the new Ford Mustang Mach-E are typically going to become costly very quickly.
The takeaway here is that, with proper care, an EV battery pack should last far beyond 100,000 miles before its range becomes limited.
Speaking of range loss, Alex L. Dykes said that the cars 88-kWh (usable capacity) battery pack is rated by the EPA at 270 miles,
but that range loss is quite minimal at a one-year, 10,000-mile mark. The 2022 Mustang Mach-E reaches 0-60 miles per hour in just 4.8 seconds,
thanks to its extended-range 88-kWh battery in an electric, four-wheel-drive version.
