I am seeing many people not charging to 100% and draining down to zero. Most are recommending charging at 20% and maxing it out at 80% to prevent battery degradation. So people are using 60% of the battery from day 1...but every metric I've looked at takes a Tesla battery to degrade down to 60% after 20-30 years. So why artificially degrade your battery down to 60% on day one in fear that in 30 years..it'll may actually degrade down to 60%? So the payback period starts after 30 years. Everyone keeping their Tesla for 30 years here?
