New research shows electric vehicle batteries degrade far slower than owners expected, retaining approximately 90% of their original usable capacity after 150,000 kilometers of driving.

The study addresses a primary concern for EV buyers: battery longevity and replacement costs. Data indicates that typical EV batteries maintain substantial functionality well beyond the distances many drivers accumulate over vehicle ownership. This finding has direct implications for used EV markets and total cost of ownership calculations. A battery retaining 90% capacity at 150,000 km suggests vehicles can reliably serve multiple owners without significant performance degradation during their typical lifespan. The research supports manufacturer warranty claims, with most EV makers guaranteeing battery capacity for 8-10 years or 160,000+ kilometers. Real-world performance aligning with these promises could accelerate EV adoption among price-conscious buyers who previously viewed battery degradation as a major financial risk. Battery degradation varies based on climate, driving patterns, and charging habits, but the study's average figures provide confidence that early EV concerns about premature battery failure are largely unfounded.
