What is the optimal mileage to replace the battery of a Nissan Leaf?

I've been driving my Nissan Leaf for over 7 years now and I'm starting to notice a decline in battery life. I have around 50,000 miles on it currently. Is there an optimal mileage to replace the battery before it starts causing issues? Any tips on prolonging battery life?

It's generally recommended to replace the battery of your Nissan Leaf after around 100,000 miles. However, factors like driving habits and temperature can also affect battery life. To prolong battery life, avoid frequent fast charging and try to keep your Leaf in a cool environment.
