What are some common issues with the Nissan Leaf's battery?

I recently purchased a used Nissan Leaf and I'm noticing some battery performance issues. What could be causing this and how can I address it?

One common issue with the Nissan Leaf's battery is capacity loss, which is when the battery is no longer able to hold as much charge as it used to. This can be caused by frequent fast charging or extreme temperatures. To address this, try to avoid frequently using fast charging and park in shaded areas to minimize exposure to extreme temperatures.

Another issue to watch out for is rapid battery aging, which is when the battery's capacity decreases significantly over a short period of time. This can be caused by frequent deep discharges or overcharging. To prevent this, try to keep the battery charged between 20-80% and avoid fully draining the battery on a regular basis.

Other potential issues with the battery include faulty cells and communication errors. If you suspect that these may be causing your battery issues, it's best to take your car to a certified Nissan Leaf technician for diagnosis and repairs.
