Ford says its electric-vehicle batteries retain more than 90% of their health on average after 100,000 miles, drawing on data from vehicles driven in the US and Canada. One report also outlines Ford’s battery-care advice; the available centre-side evidence gives only a brief characterization of the findings.

Ford says the Mustang Mach-E battery retained 92% health on average over five years; across its EV lineup, batteries averaged more than 90% health after 100,000 miles.
Ford’s data covers more than 36,000 vehicles that traveled two billion miles in the US and Canada, and 95% of vehicles were between 87% and 97% battery health.
Ford recommends home Level 2 charging for daily use where possible, limiting DC fast charging to longer trips, and avoiding charging in extreme temperatures when feasible.
