They only pay for themselves if the life claims turn out to be
true. So far, none of the lithiums I've tested except A123
cells have met their specs. In particular, most lithiums are
shot in 3-5 years.
We're getting to the point where a fair number of people are into the 3-5
year age with their lithium packs (I'm only starting my 2nd year with mine).
It'd be pretty important to know how many are having to replace packs so
early when the expectation should be 6-10 years; something like 2000-3000
cycles (in my car that should be at least 80,000 miles, though I'm guessing
I won't make that for other reasons).
I believe my car was put into service in January 2009:

It has cells from three different batches. It started with 45 cells and
then three more added. Car currently has about 40k miles but is now
being driven very little. I've replaced about 8 cells. The first 4-6
were probably killed by malfunctioning BMS modules. The most recent 2-3
died without explanation. That is, probably just age.
I had hoped to drive the car well over 100k miles but it now competes
poorly with a Tesla and I no longer hope for 100k miles.
