I have had several older Sony readers recently bought that had very quick self discharge as received, like 48 hours or so. Battery too low to turn unit on. After a dozen or so charge and discharge cycles the batteries are much improved. The best are still showing full charge bars after 4 days since being charged. I am watching several units to decide which one to try replacing the battery on first.
