How long do Ford Electric Vehicle Batteries last?
As is the case with all batteries, the High Voltage lithium-ion battery capacity will decrease over time and with use. While gradual capacity loss with time and use is considered normal wear and tear, Ford Motor Company warrants the High Voltage battery against excessive capacity loss for a period of eight years 160,000 km (100,000 mi) whichever of those occurs first, from the date of first vehicle registration.
If a Ford Certified Electric Vehicle Dealer determines that the useable battery energy capacity is less than stated in the following table of the lithium-ion battery’s original capacity when new, then this level of capacity loss is considered excessive.
