I'm suprised no one has mentioned the fact that batteries life gets much shorter as the batteries age, especially when they experience multiple deep discharges. There is no such thing as a battery that will last for 20 years aside from wet cells(with a lot of maintenance), and some of the best VRLA batteries won't last more than 5. Who manufactures the batteries anyways? I'd be interested to see resistance data and discharge data as these batteries age because I doubt people will want to fork over the $5-10k for replacing the batteries after 5-10 years when their car won't maintain voltage. This would certainly lead to an abundance of new junk. Also, what happens if a cell goes into thermal runaway, Is there even any type of monitoring there?
