What is the Nissan Leaf 30kwh battery degradation rate?

I recently purchased a Nissan Leaf, and I didn’t consider its battery degradation rate until now. Do you know what the 30kwh battery degradation is like in the Nissan Leaf?

Great question! The rate of degradation varies depending on a combination of different factors, including the type of battery, the conditions in which it is used, and how it is charged and maintained.
In the case of the Nissan Leaf, the 30 kWh battery has been reported to have a generally low rate of degradation. According to Nissan, the 30 kWh battery in the Leaf is designed to retain at least 70% of its capacity after 8 years or 100,000 miles of use. This means that after 8 years or 100,000 miles, the battery should still have a capacity of at least 21 kWh.
It’s worth noting that your Leaf’s actual battery degradation might not reflect these numbers because battery degradation is sensitive to how the vehicle is driven and charged and the local climate and driving conditions. Some Leaf owners have reported higher rates of degradation, while others have experienced less degradation than expected. But in general, the 30 kWh battery in the Leaf has been well-regarded for its low rate of degradation.
If you find that your Nissan Leaf’s battery is degrading, Nissan provides an eight-year/100,000 mile warranty on the Leaf’s battery, so if you’ve purchased your Leaf in the last eight years or its mileage hasn’t reached the 100k mark yet, you’ll be able to get a replacement from Nissan.
