First of all, do not fully discharge your battery. This is what happens when you do.
Do a SMC/PRAM reset.
Leave it plugged in for a while and start using it plugged in.
Best idea to keep it plugged in when you're close to an outlet and let it run on it's own power once in a while. When it gets down to 80% charge it back up.
Once a month, use it until it's down to 40%, recharge it back up to keep it in optimal condition.
Again, never let it discharge to 0%.
