Study Finds EV Batteries Retain Most Capacity After 150,000 Kilometers

A new study reported by Ars Technica suggests that electric vehicle (EV) batteries hold up better over time than many consumers have assumed, potentially easing a common concern among prospective EV buyers.

According to the report, used electric vehicles were found to retain approximately 90 percent of their original usable battery capacity even after being driven 150,000 kilometers.

Battery degradation has long been cited by consumers and industry analysts as one of the primary hesitations around adopting electric vehicles, particularly regarding the long-term value and reliability of used EVs. Concerns have centered on the cost of battery replacement and the potential for reduced driving range as vehicles age.

The findings, as described by Ars Technica, indicate that real-world battery performance may be more durable than earlier fears suggested, which could have implications for the resale value of used electric vehicles and consumer confidence in the technology.

Ars Technica did not specify additional methodological details, such as the number of vehicles studied, the makes and models included, or the entity that conducted the research, in the excerpt available at the time of this report.

The broader implications of the findings for EV manufacturers, warranty policies, and the used-vehicle market were not detailed in the available source material.
