Electric vehicle batteries maintain approximately 90% of their original capacity after 150,000 kilometers, according to a comprehensive study based on over 500,000 tests conducted between 2022 and 2026 across 20 popular car models.
The research reveals that climate plays a significant role in battery longevity. Vehicles operating in hotter regions experience accelerated degradation, a factor that buyers in warmer climates should consider. Keeping batteries charged at very high levels for extended periods also contributes to faster capacity loss, suggesting that moderate charging practices can help extend battery lifespan.
This data provides reassurance for electric vehicle owners concerned about long-term battery performance and resale value, demonstrating that modern EV batteries are more durable than many initially assumed.
