My understanding is that 2 & 3 are problems with the original (20kWh) Leaf model. Which possibly led to a rumour about the 40kWh models, that the OP has.

My Leaf from 2019 has 100% battery health and I always charge it to 100%. I almost never use fast charging though since it is a commute kind of car.

Is that the health reported by the car dashboard, or by LeafSpy? The dash has some wiggle room in its 1-10 display an IIRC it will display 100% until the SoH is below like 90%...

Obviously they are reporting the dashboard number. The first bar drops at 85%. For a 2019, it is probably getting close to dropping its first dashboard bar.

		After 25 years in the industry I should know that there is always someone that have read more forums and researched more :) Either way, the car is 6 years old. At this rate the battery will still be pretty fine when it is 15 years old and ready for retirement. Never charging it above 80% is not worth the hassle. It is like never using your left hand for the fear of hurting your left hand. You are crippling your car by overthinking.
