As electric vehicles gain popularity, many drivers are still curious—and sometimes skeptical—about long-term battery health. Ford has now shed light on the battery life expectancy of its popular all-electric crossover, the Mustang Mach-E. According to Ford’s own data, the high-voltage battery used in the Mustang Mach-E is engineered to last at least 10 years, with 90% of its original capacity retained at 100,000 miles. This revelation offers peace of mind for prospective EV owners concerned about battery degradation over time.

This durability assessment is based on Ford’s internal valuation study and field data collected from real-world Mach-E usage. Given that EV batteries are often one of the more costly components to replace—frequently running into several thousand USD—this longevity is welcome news. Ford’s commitment to designing long-lasting electric drivetrains is helping to combat common misconceptions about EV reliability and total ownership cost.

Supporting this data is the real-world example of David Blenkle, who owns a 2022 Ford Mustang Mach-E Premium. In just three years, he’s driven over 250,000 miles and reports excellent battery health, with a max range still close to the original EPA-rated figures. This impressive performance far exceeds expectations and showcases how well-maintained EVs can stand the test of time.

Blenkle attributes his success to consistent home charging, keeping the battery under 90% charge for daily use, and taking advantage of regenerative braking—which has even spared his brake pads from replacement so far. His experience not only validates Ford’s data but also reinforces how EV maintenance practices can maximize performance and extend battery life.
