Electric vehicle owners have long wondered how long their batteries will last, with concerns about degradation and replacement costs. New research indicates that these worries may be overblown.

According to a study reported by Ars Technica, used EVs retain approximately 90% of their original usable battery capacity after 150,000 km of driving. This finding suggests that battery degradation happens at a slower pace than many drivers feared, which could make used EV purchases more attractive and extend the practical lifespan of these vehicles.
