My 2015 Leaf has 148k on it and still drives like new. The battery is down to about 85% but this is pretty old lithium tech with very early thermal controls on it.
I quick charged my Leaf over 350 times in 2 years and it barely degraded the battery.
I got a `EA530 exide 079te` for my leaf just over a year ago and so far it's still working perfect.
When I replace mine I went with the Optima Yellow Top. Seems to be hanging in there 6 years later.
I just ordered the energizer lithium fob battery, will see if it lasts longer than the regular energizer which in my case was 3 years
I'm in central Texas and the Leaf does just fine for in city driving. The batteries run hotter than a liquid cooled battery does of course but they are capable of operating at Texas summer temperatures. Where they struggle is on long highway trips. High speeds mean more load on the battery which also means more heat and more likely to have the car limit power due to battery temps. I have noticed that Leafs in Texas do tend to show more battery degradation and less capacity than leafs that are in cooler climate.
I have a 2015 Nissan LEAF SV. In -25C or colder (and to be fair, it's rarely -25C (not counting the windchill) during the day), with moderate heat on (set heat to 19C or less) plus heated steering wheel and heated seats (both of which use relatively very little power), I can lose a good 60% of my range
Our other car, the 2016 Leaf, kinda is the embodiment of all the negative talking points you hear about, since it's an older EV: It uses an outdated & slower charging standard, has a small battery, and has significant battery degradation (29%) since Nissan decided, in their infinite wisdom, to not give the Leaf a coolant loop for the batteries. (Heat is the biggest killer for EV batteries).
