Battery OEM Nissan or Tesla

As an owner of a 2016 model S (bought new) with 228k miles on it, still on original battery with a range reduction of less than 15% compared to new.

Just replaced mine in my model 3, it lasted about 4.5 years before I get the alert on my app. Had it replaced in less than 20 minutes via mobile service in the app (there was already a tech in the area).

After several tests they were able to get the battery fail code they were looking for. Nissan replaced the battery with a new one, and so far so good.

I had a 12v battery give me a low voltage warning and they just came around and changed it.

It's a Tesla thing.

Tesla doesn't keep a buffer zone at the top end of the battery. 100% means 100% in a Tesla. Tesla advises to only use 100% when you need the extra range.

My tesla model y recommendation is 90%. I know lfp batteries are recommended to do 100% at least weekly. We do 90% but drive the car about 100 miles every work day so it doesn't even sit at 90% for very long, maybe 3-4 hours.

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

2019 model 3 SR with 10% loss based on full charge at 52k miles.

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Leaf, kinda is the embodiment of all the negative talking points you hear about, since it's an older EV: It uses an outdated & slower charging standard, has a small battery, and has significant battery degradation (29%) since Nissan decided, in their infinite wisdom, to not give the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).
