My nine-year-old Leaf's battery is also fine :)

do you live somewhere never very hot?

Correct

I have 83% capacity on my Leaf at 7 years and 75k miles. I live in Kansas City where it typically ranges from 0F to 100F over the year.

Average monthly high temperature never goes above 90f in Kansas so while it gets a few extreme days a year it really doesn’t get hot for any significant period. https://www.timeanddate.com/weather/usa/kansas-city/climate

The average monthly high temperatures in Las Vegas by comparison are 104f in July, 103f in Aug, and 100f in June. https://www.timeanddate.com/weather/usa/las-vegas/climate

Critically for battery degradation high temperatures when in actual use get well above ambient temperature. So, if you avoid driving in the heat of the day things can look better than local climate suggests.

Kansas City (Missouri)

Kansas City (Missouri) and Kansas City (Kansas) have are the eastern and western half of the same city, and therefore have essentially the same climate. Between the two states, Missouri actually has the largest portion of the city.

I’m down to 8 bars recently on my 2012 Leaf, at just under 70k miles. I’m still extremely happy with the car, though I now work from home. I live in the Portland OR area, which has started to experience more extreme temperatures over the last decade

That 116 degree day last year... x_x I have central A/C and it couldn't keep up. It was 85 degrees in the house and it sucked. Can't imagine all the poor sods that didn't even have A/C. I probably would have just sat in the bath tub all day.

And then last month when we had a 75 degree Thursday followed by snow on Monday...

I just want some nice weather so I can take my new mountain bike to Gateway Green.

I'm glad it's working pretty well for you folks. The info on leafs was that charging with Chademo, higher power charging, was really hard on the batteries because they'd get hot and leafs don't have a battery management system. Do you think that was an unwarranted opinion? Maybe you didn't do that much?

Not very frequently. I’d say I charged with ChaDeMo 2-3 a month max, and only if I was really in need. The chargers aren’t very common to begin with, so I can’t imagine many people using them daily.

For me it was a “drive into town, and back, and back in, and back” situation where I didn’t have the luxury of charging for hours at a time.
