Battery life  I use my car a lot. About 30,000 miles per year.
Can anyone tell me what the battery life expectancy is? If I
have, say 100,000 miles on the battery, what kind of range will
the battery have left? 90% of my travels are under 225 miles and
that's why I ordered a S with the biggest battery. But, if the
battery is rated at 265 miles and at 100,000 miles it only has,
say 70% capacity left, that puts the range at about 185 miles.
That just won't work for me. Also, does anyone know what Tesla's
policy is on battery replacement. Will they replace the battery
if it's under 80% capacity? 70%? 60%? or what? Thanks.  The
following thread over at TMC has a lot of related discussion:
Seems like the replacement policy might work for you. Warranty
would only cover flaws, not normal degradation.  As a side note,
the "safety margin" TM appears to have allowed itself is about
100%, which is to say the stated decline rate is about double
what they actually expect (and have considerable Roadster
experience to draw
