Electric car batteries are designed to provide reliable and efficient power for your vehicle. The lifespan of an EV battery can vary depending on several factors. Every EV comes with a battery warranty that is good for eight years or up to 100,000 miles. Depending on how and where you drive, your battery could last as long as 20 years.

So, what factors impact your EV’s battery? They include:

• Battery Chemistry: Diverse EV models employ various battery chemistries, such as lithium-ion, each showing a promising impact on lifespan. Modern EVs are often equipped with cutting-edge battery technologies known for their robustness.
• Temperature: While extreme weather conditions can pose challenges, the good news is that with proper storage and charging practices, your battery can thrive even in these environments.

Additionally, adopting a smooth driving style and adhering to regular charging practices can help preserve your battery's health over the long term.

A new study from Stanford’s SLAC-Stanford Battery Center suggests your electric vehicle’s battery might stick around much longer than standard lab estimates indicate. Their research found that when EV batteries undergo real-world driving patterns—such as stop-and-go traffic, short trips, and frequent parking—they age more slowly than batteries tested under constant, steady use.*

The researchers tested 92 commercial lithium-ion battery cells across multiple discharge profiles, comparing the standard laboratory method (constant cycling) with more realistic driving behavior. The closer the profile mimicked actual use—pauses, braking (which recovers energy), and varied loads—the more life the battery showed. They estimate that real-world use could extend battery life by as much as 40 percent beyond conventional projections.*

One surprising finding: short, sharp accelerations didn’t accelerate aging as presumed—in fact, they correlated with slower degradation. Letting the battery rest during parking periods also helps. The conclusion: Lab tests may be overly pessimistic. This is good news for EV drivers who expect their batteries to last for many years on the road.

Next up in our discussion of “How long do electric car batteries last?”, we’ll offer our top suggestions for extending your battery’s lifespan. By following these essential tips, you can potentially keep your battery in ideal shape for longer. Here are some positive steps you can take to ensure your battery stays in top-notch condition:

• Charging: Charge your EV regularly and keep the battery within a healthy range. We also recommend using traditional charging whenever possible. A fast charger is occasionally fine, but it shouldn’t be used daily.
• Avoid Extreme Temperatures: Park your EV in a shaded or temperature-controlled area to shield the battery from extreme heat or cold.
• Smooth Driving: Embrace a gentle driving style. Gradual acceleration and deceleration reduce stress on the battery and promote longevity.

By following this advice, you can maximize the benefits of your EV and enjoy more efficient drives.
