Ford says its electric vehicle batteries retain more than 90% of their original health on average after 100,000 miles, based on real-world data collected from more than 36,000 vehicles across the United States and Canada.
The automaker has tracked its EV fleet since the launch of the 2021 Mustang Mach-E, gathering data from vehicles that have collectively travelled approximately two billion miles. The findings indicate that battery degradation has remained relatively limited across its electric vehicle lineup.
The Mustang Mach-E, Ford’s first purpose-built electric crossover, has retained an average of 92% battery health over five years, according to the company.
High-Mileage EVs Show Limited Battery Degradation
Ford’s analysis covers the Mustang Mach-E, F-150 Lightning and E-Transit. Across the lineup, battery packs maintain more than 90% health on average after 100,000 miles.
The company said 95% of vehicles fall within a battery health range of 87% to 97%, highlighting differences in usage patterns and operating conditions.
Among owners of 2021 model-year electric vehicles, more than 2,000 have driven beyond 100,000 miles using their original battery packs, with average battery health remaining above 91%.
More than 30 vehicles have also exceeded 200,000 miles, retaining an average of approximately 88% battery health.
Ford said the findings are helping it provide owners with practical recommendations for maintaining battery performance over the long term.
Ford Shares Tips for Maintaining EV Battery Health
The automaker recommends using home Level 2 charging for everyday driving where possible, while reserving DC fast charging primarily for longer journeys.
Temperature management is another important consideration. Charging in extreme heat or cold can affect battery performance, while battery preconditioning helps bring cells closer to their preferred operating temperature.
Ford also recommends parking in shaded areas during hot weather to limit prolonged exposure to high temperatures.
Owners can use the Ford App to access charging recommendations tailored to their specific vehicle and battery system.
Battery chemistry also influences charging guidance. The 2021 Mustang Mach-E uses nickel-cobalt-manganese (NCM) battery technology, while some newer Ford models use lithium iron phosphate (LFP) chemistry. Ford recommends charging LFP-equipped vehicles to 100% periodically to support battery management system calibration and accurate range estimates.
Battery Data Supports Ford’s Next-Generation EV Development
Ford is using its accumulated vehicle data to improve battery management and inform the development of its next-generation electric vehicles.
The company is applying lessons from its Universal Electric Vehicle (UEV) platform, which will underpin future models, beginning with a midsize electric pickup.
Ford plans to open pre-orders for the pickup, identified in the supplied announcement as the Fathom, in early 2027, with a starting price of $28,350.
Meanwhile, the 2027 Mustang Mach-E is already on sale from $39,995. The latest model drops the standard-range battery previously offered on the 2026 version and comes with an 88 kWh battery as standard.
Ford estimates that the rear-wheel-drive configuration can achieve an EPA-rated range of up to 320 miles.
The company’s real-world battery findings provide additional insight into long-term EV ownership costs and performance, while supporting its efforts to improve battery technology and charging recommendations for future electric models.
