Don't.
Discharging the battery "completely" will make its protection circuit
cut off, making it much harder to restore (LiIon batteries are not
supposed to be discharged too much, it damages them). In fact, that is
probably precisely what happened: the GTA01 did not switch to the
correct charging mode (because it needs to be able to power on to do
so), and discharged the battery too much.
The way to recover from it on GTA01 is to "jump-start" the battery
(since the GTA01 cannot boot only on USB power, which would allow
enabling the charger), which is not a recommended thing to do (and might
in fact be dangerous).
