How fast does a 40 kWh Nissan Leaf battery degrade?

I got a new Nissan Leaf just last year and I’m shocked to hear that the 40-kWh battery is known for degrading quickly in the first year. Is this true? How fast does a 40-kWh battery degrade?

Rest assured, battery degradation is completely normal! Nissan considers 80% battery capacity after five years to be acceptable, but if the 40-kWh battery for your Leaf drops below 70% capacity, check with Nissan to see if it’s still under warranty.
Most electric vehicle batteries (including those for your
Nissan LEAF
) typically degrade by one to three percent over the first year and up to a total of 20% over the first five years of ownership.
Nissan offers an eight-year or 100,000-mile warranty for the 40-kWh battery. Keep in mind that your driving style, charging habits, and environmental conditions are the biggest factors in how quickly your battery degrades.
If you’re not sure if the Leaf battery is degrading too fast,
make a service appointment
and get your car inspected.
