Hello Everyone, I have a couple of questions regarding the battery lifetime+degradation: 1. How long will the Tesla's batteries last? is it 8 like the warranty or maybe 10 or 15?! can we even know for sure? 2. I live in a fairy convient area for EV's, it is rarely raining\snowing and temps are mostly at the 15~25 C(59F~78F) zone which I heard is really good for EV's(bad performance on cold weather and range is reduced due to snow\rain) however at some days especially in the summer the temps are really hot some weeks around 35C or even 40C! (95F and 104F) is it any good to purchase an EV let alone a very expensive EV(Tesla model S) in such warm conditions due to Degradation? Thank you for your time!
