Ok. I don't know how long it will be until I can get a new battery. Also, my charger makes a fairly audible buzzing sound. I know it's supposed to, but this sound seems a little off. It's a little more audible then I think it should be. It would make a lot of sense if it was the charger and not the battery, since I have had other problems with it too. For example, I plug in the 770 and it says "Charging" like normal, but then, about 2-3 seconds later, it will pop up a weird "Not Charging" message. Then, I usually either have to shut down the tablet and wait for it to charge without the OS loaded, or unplug the charger and wait a while.
