EV batteries, powered by lithium-ion technology, typically last significantly longer than traditional vehicle components. Most manufacturers warranty their batteries for 8 years or 100,000 miles, with California extending coverage to 10 years or 150,000 miles.

Battery Degradation Factors:

• Temperature exposure
• Charging cycles
• Natural aging over time
• Operating conditions

Recent Stanford research shows EV batteries perform better in real-world conditions than laboratory tests suggest, potentially lasting 40% longer than previously estimated. On average, EV batteries degrade only 2.3% per year, potentially lasting around 280,000 miles – double the typical ICE vehicle lifespan of 133,000 miles.

Tips to Extend Battery Life:

• Follow manufacturer guidelines
• Keep software updated
• Maintain moderate storage temperatures
• Park in shaded areas or garages
• Minimize rapid charging use
• Regular use is beneficial

Battery Technology Improvements:

• 97% cost reduction over 30 years
• Increased energy density
• Better range capabilities
• Improved degradation resistance
• Some manufacturers targeting million-mile batteries

Second Life Applications:

• Batteries remain useful at 70% capacity
• Can power home solar systems
• Used in commercial energy storage
• Sustainable recycling options available

EV batteries consistently outperform traditional vehicle powertrains in longevity and reliability. With advancing technology and proper maintenance, modern EV batteries can provide reliable service for well over a decade, making electric vehicles an increasingly practical choice for long-term use.
