Ford EV Batteries Retain Over 90% Health After 100,000 Miles

Ford reported that its electric vehicle batteries retain more than 90% of their original health on average after 100,000 miles, providing encouraging real-world evidence of long-term battery durability.

Since launching the 2021 Mustang Mach-E, Ford collected data from more than 36,000 vehicles that traveled a combined two billion miles across the United States and Canada. The Mach-E’s batteries retained an average of 92% health over five years.

Across Ford’s EV lineup, including the Mustang Mach-E, F-150 Lightning, and E-Transit, 95% of vehicles recorded battery health between 87% and 97% after 100,000 miles.

More than 2,000 owners of 2021 model-year EVs exceeded 100,000 miles on their original batteries, averaging more than 91% health. Another 30-plus vehicles surpassed 200,000 miles while retaining an average of 88%.

Ford is using this data to improve battery technology and provide owners with personalized charging recommendations through the Ford App. The findings will also inform development of its next-generation electric vehicles using the Universal Electric Vehicle platform.

Ford’s Tips for Maintaining EV Battery Health

Ford recommends using Level 2 home charging for everyday driving and reserving DC fast charging primarily for longer trips. Owners should also avoid extreme battery temperatures when possible, use preconditioning to optimize battery temperature, and park in shaded areas during hot weather.

Charging recommendations depend on battery chemistry. Some newer Ford models use lithium iron phosphate (LFP) batteries, which benefit from occasional charging to 100%, while other battery types have different recommendations.

Ford’s real-world findings challenge concerns about premature EV battery degradation. Retaining nearly 90% or more of original battery capacity after 100,000 miles demonstrates that modern electric vehicles can deliver substantial longevity without requiring battery replacement.

EVinfo.net’s Take: AVILOO Expands Independent EV Battery Certificates Across the U.S. Used EV Market

Ford’s reporting and advice about its EV batteries is very commendable and very useful. Something else very useful to U.S. dealerships and automotive marketplaces is AVILLO’s independent EV battery certificates.

AVILOO, an independent electric vehicle battery diagnostics provider operating in 70 countries, is expanding its services into the U.S. used EV market. The company is introducing business-to-business (B2B) battery testing for electric vehicles and plug-in hybrids, with consumer services planned next.

Founded near Vienna, Austria, in 2018, AVILOO began U.S. operations in Denver, Colorado, in 2024. Its testing products include the comprehensive PREMIUM Test and the FLASH Test, developed using data from thousands of battery assessments.

Independent Battery Certificates Build Used EV Buyer Confidence

An April 2026 international survey of automotive businesses conducted by AVILOO found strong demand for independent battery certification.

Among respondents, 92.9% identified transparency and buyer confidence as key reasons for using battery certificates. Additionally, 93.4% said independent certification increases sales credibility, and 88.8% emphasized the importance of manufacturer-independent results. Some 84.4% reported that customers actively request battery certificates.

The commercial benefits were also significant. Nearly half of surveyed businesses (46.2%) reported higher vehicle selling prices, while 44% experienced shorter inventory holding times. Another 74.7% use battery certificates to reduce complaints and returns by evaluating vehicles before purchase.

AVILOO’s FLASH Test differs from quick assessments that rely solely on battery management system data. Its independent testing evaluates battery health, State of Health (SoH), and potential defects in approximately three minutes, covering more than 96% of available vehicle brands.

The survey included dealerships, fleet operators, vehicle traders, and testing organizations across multiple European markets. Overall, 94.4% expressed satisfaction with independent battery certificates, and 92.4% would recommend them.

AVILOO Appoints Brett Lippel to Lead North American Expansion

AVILOO appointed well-respected automotive industry veteran Brett Lippel CEO of its North American operations to accelerate U.S. growth.

Lippel brings more than 20 years of leadership experience across automotive, mobility, fintech, logistics, and software, including senior positions at ShipYourCarNow.com, Lendgistics, Midway Auto Group, and TrueCar.

He will focus on expanding AVILOO’s services among dealerships, fleets, remarketing companies, and automakers.

Independent battery certification can address a major obstacle in the used EV market: uncertainty about battery condition. Objective testing gives buyers greater confidence, helps dealers establish vehicle value, and provides a more transparent foundation for used electric vehicle transactions.
