There are two factors which affect batteries:
1. Number of charge cycles.
2. The physical age of the battery.
For a laptop, #1 dominates, but for a reader, #2 does. Even if a light doubled the number of charge cycles (which is being on the pessimistic side), it would still be the age of the battery which would determine its life. A lithium battery will typically have a lifetime of around 5-7 years.
