RE: What is a Kindle's life expectancy?

Those batteries are only good for so many charging cycles and also just with time they'll start to not hold a charge for as long - as Margaret Lake mentions with her old Kindle 1.
Lithium-ion Polymer batteries should last about 300 - 500 full recharges before capacity drops to 80%. Assuming a weekly recharge that's at least six years. And if you can live with the loss of capacity they should last over a 1,000 full charges before they give up the ghost. (A full recharge = 2 x 50% recharges = 10 x 10% top ups etc.)
I don't think I would even notice the difference between the original capacity and degraded to 80%. It would just mean charging a couple of days earlier.
There doesn't seem to be any evidence of even the oldest eInk displays wearing out.
