Unlike most other EV's, the Nissan LEAF uses passive air cooling for its battery pack. This has been a point of contention between EV enthusiasts and potential buyers of this design choice. But it can lead to faster battery degradation, say some, especially in hot climates or when fast charging repeatedly. Some say it’s not really a big deal for most drivers. The debate is usually about long term ownership costs, resale value and what kind of climate and driving pattern the car is suitable for. It’s a subject that gets brought up quite often when comparing the LEAF to other EVs, or talking about it’s longevity as a used car.
