EV Battery Degradation: Overblown Fears?
2025-08-18
Concerns about short lifespan of EV batteries are widespread. This article debunks this myth, analyzing two types of battery degradation: calendar aging and cycle aging. Real-world data shows degradation is far slower than feared, especially after 20,000 miles. Studies of thousands of EVs show over 80% capacity retention even at 200,000 miles. Manufacturer warranties of 8-10 years or 100,000 miles further support this. While degradation is unavoidable, mitigating factors include avoiding extreme temperatures, charge levels, and frequent fast charging. In short, anxieties around EV battery life are largely overblown; they last far longer than many believe.
