Questions of battery degradation over the years, warranty coverage, and battery pack I've read a lot and searched but didn't find these answers, if anyone knows, or has a link to an appropriate thread I'd appreciate it! First, what is the expected battery degradation over 8 years of ownership? IE if we are expecting 260-300 miles per charge in year 1, how much less should we expect in years 2-8? How does the 8 year battery warranty cover this degradation? Is there an expected %age that is or isn't covered by the warranty? If I'm only getting 100 miles by year 3, would that be covered by warranty? And lastly, after 8 years, what's it going to cost to put a whole new battery pack in this car? $20k? We'd hope battery prices would come way down, but who knows I guess. That would certainly kill 8 years of fuel savings. And really, really hurt resale! I have my deposit down, but my brother-in-law apparently was told by Tesla (he may have misunderstood...) to expect 25% per year battery degradation. He immediately went out and bought a Lexus Hybrid after hearing that (and I can't blame him if that's true...).
