Also any decent battery will have a safety mechanism to prevent overcharging (meaning you can leave it plugged in). And 4-6 hours is just overkill as a needed charge time. That's comparable to tablets with seven times the battery capacity.
You might be able to replace the battery yourself. I remember reading somewhere that ereaders basically used dumb phone batteries. But then again I have no idea.

500 recharges. Works out to roughly 3 years. One charge cycle is a period
of use from fully charged, to fully discharged, and fully recharged again. Use a
two to three year life expectancy for batteries that do not run through complete
charge cycles.
Rechargeable Lithium-Ion batteries have a limited life and will gradually lose
their capacity to hold a charge. This loss of capacity (aging) is irreversible. As
the battery loses capacity, the length of time it will power the product (run time)
decreases. So should be longer if there is a few weeks in between charges.
