New data indicates that electric vehicle batteries are lasting significantly longer than initially predicted, with modern batteries retaining up to 95 percent of their original range after five years. This improved longevity is attributed to advancements in battery chemistry, smarter management systems, and more effective thermal regulation, as well as the dynamic nature of real-world driving conditions which are less taxing than constant lab discharge tests. Consequently, EV batteries could realistically last 20 years or more, alleviating consumer concerns about expensive battery replacements and encouraging wider adoption. AI
