sample quote

Recurrent surveyed just over 15,000 EV owners and compiled some of the most detailed battery health data ever assembled, showing that EV batteries are lasting far longer than critics and owners have anticipated. Of their massive group of owners, only 1.5% had replaced their batteries outside of a recall or warranty period. Most of those were older Nissan Leafs lacking liquid battery temperature control systems.

Recurrent’s survey included data from 13 vehicle models, including the
Tesla Model S, Model 3, and Model Y; Chevy Bolt, Bolt EUV, and Volt; Hyundai Kona; BMW i3; Audi e-tron; Nissan Leaf; Hyundai Kona and IONIQ 5; and Ford Mustang Mach-E.

Recurrent found that battery degradation was not a linear phenomenon.
From each of the surveyed groups, while the EV range peaked within 10-20,000 miles, it quickly degraded and flatlined as it approached 100,000 miles.
