There's two factors which affect the capacity of lithium battery: number of charge cycles is one, but simple ageing is a more significant one. When a lithium battery is first charged, the clock starts ticking; a 3-year-old battery will typically have lost a third of its original capacity; after 5 years it'll probably be completely dead. Many people with older readers like the Sony PRS-505 or the original Kindle have certainly run into battery issues already.
