Maybe good to summarise what has been said about the Sony battery in this and many other forums.

The Sony reader uses a small 3.7V Li-ion battery pack that can be charged with a 5 volt charger through the mini USB plug (bottom left) or via the barrel plug (bottom right)

Charging via the mini USB plug can only be done with a PC that has recognised the charger. External USB chargers don't work and will in fact deplete the battery further i.s.o. charge. If the PC goes on stand-by, charging is interrupted.

Charging via the barrel plug can only be done using an external charger. You can get one expensively as a Sony accessory or you can buy a charger for the PSP. The pocket PlayStation charger uses the same plug and charge voltage/current to charge the reader. Prices vary, but are well below the official Sony one. Charging through an external charger goes faster and according to some sources also deeper (i.e. higher charge)

Charging through a computer takes a lot longer and according to Sony's own documentation it can take 40 minutes before there is enough charge in the reader for the screen to refresh. So wait before you think that your reader has bricked up.

I have no experience yet about the 7000 page turns on a charge.
