What happened
Ford reported that its electric vehicle batteries keep, on average, more than 90% of their health after 100,000 miles, about 160,000 kilometers. The company collects data from more than 36,000 vehicles that have logged two billion miles in the United States and Canada since the 2021 Mustang Mach-E launched. That model’s battery has kept 92% of its health on average over five years.
Why it matters
Battery life is one of the common doubts when buying an electric car. Ford says this holds across its lineup, which includes the F-150 Lightning and the E-Transit. Real-world usage data matter more than lab tests, though they come from the company itself, so they are best read as a manufacturer’s report.
The number
Some 95% of vehicles fall between 87% and 97% battery health.
Context
Of 2021 model owners, more than 2,000 passed 100,000 miles on the original battery with an average above 91% health, and more than 30 exceeded 200,000 miles with an average of 88%. Ford offers care tips: charge at home with a level 2 charger for daily use and save DC fast charging for long trips, avoid charging in extreme temperatures, precondition the battery and park in the shade in summer. The 2021 Mach-E uses an NCM chemistry battery; some newer ones use lithium iron phosphate (LFP), which should be charged to 100% from time to time.

What’s next
Ford will apply what it learned to its Universal Electric Vehicle platform, which will underpin its next models starting with the Fantom pickup next year. Electrek’s author warns that measuring a battery’s long-term health is like looking into space: the information received is already old.
Bottom line
The data are favorable, though it remains to be seen how newer models age.
