EV Durability: Batteries Keep 95% Range After 5 Years

A comprehensive study analyzing data from over 15,000 electric vehicles in the US has debunked widespread consumer fears regarding battery degradation. The research, conducted by Recurrent and Geotab, shows that modern EV batteries retain 95% of their range after five years.

The study attribute this durability to advanced thermal management systems and refined chemistry in newer lithium-ion packs. Unlike early EVs, which suffered rapid range loss in hot climates, modern models use liquid cooling to keep battery temperatures optimal.

Debunking the Battery Degradation Myth

The data suggests that EV lifespans could outlast the physical chassis of the cars themselves. This longevity should boost buyer confidence in the used EV market, where concerns over battery replacement costs have kept resale values low.

Implications for the Used EV Market

Manufacturers are using this data to lobby for longer battery warranty periods, hoping to counter consumer hesitation. As battery chemistries continue to improve, the need for costly battery replacements is becoming a relic of the past.
