Remove the back from the tablet and unplug the battery for a few minutes. Then put it back in charge fully.

There are actually quite a few "Galaxy Tab 3 teardown" videos on YouTube.

Have you tried changing the usb cable ?

Had the same problem earlier, then tried using a friends usb cable and found that the issue was due to my cable.

I know there is a method to reset the battery file but I don´t know where I read that
You have to hold some buttons for 10s while the device is off.

Try that at your own risk:

1. Turn off your Tab
2. Plug it in (wall charger)
3. Wait till it shows a charging battery
4. Press and hold menu-button 10s or more

OR

1. Turn off your Tab
2. Plug it in (wall charger)
3. Wait till it shows a charging battery
4. Press and hold menu-button + power-button 10s or more
