Re: Replacing the batteries.
Battery discharge level is one part of the equation where rechargeable longevity is concerned. The bigger problem is charging past the 'bulk charge' point. this is typically 80% of battery capacity. Charging to 100% may be needed for the occasional long journey, but generally it's best not to go above 80% and for long battery life, this should be considered the normal maximum. Generally, it looks as though most Teslas, driven reasonably sensibly, will be good for half a million miles plus.
