How long do electric car batteries last?

What people often compare electric car batteries to are the batteries in our smartphones. A lithium-ion battery in a smartphone can typically handle around 500 full charge cycles, while modern electric car batteries can last between 1,000 and 1,500 full cycles. This means that if you charge your phone or EV from 0% to 100% every day, you can expect your phone to lose significant capacity in about 2-3 years, while an electric car might take 5-7 years to reach the same point. In city driving, frequent stop-and-go traffic and braking put extra stress on the battery, accelerating capacity loss through partial charge cycles. On the other hand, highway driving tends to be gentler on the battery because it operates at a more stable temperature and workload. For example, Tesla Model 3 owners often see around a 10% capacity loss after the first 160,000 km, but as the battery ages further, that loss can increase to 20-25%.

I tried out a new electric car yesterday, and honestly, I did some deep research on that issue. Look, battery lifespan varies from manufacturer to manufacturer, but on average, we're talking 8-12 years — though it's not like it's completely useless; you can still use it even when it's down to 70-80% capacity. For example, the car I test-drove had a 60kWh battery and was guaranteed for 300km, but after 5 years, it dropped to 270km. So, it was totally fine for city driving, but for long trips, you gotta think about charging during rest stops. As for charge cycles, man, the more you charge the battery, the shorter its lifespan gets, obviously. I’d say it’s best to keep charging below 80% and avoid fast-charging stations as much as possible. I always charge mine overnight at home and top it up during the day if needed on longer drives. Even though there’s some performance loss in long-term use, the car’s ECU adapts to it over time. My advice? Keep an eye on battery health by taking advantage of free checks offered by municipalities.
