There are two factors which "age" a lithium battery: number of charge cycles, and a natural ageing process, whereby the internal resistance of the cells in the battery gradually increases. For a phone or a laptop, the charge cycles dominate, but for a reader, this is negligible: I doubt that many eInk devices get through as many as 10 charge cycles in a year. It's really only the "increasing internal resistance with age" factor that matters.
