Welcome to Android Central! Just charge it up to 100%, which should only take an hour or so (if the battery is starting at around 50%). If you want, you can continue charging for another hour for the "saturation charge" (see here: Charging Lithium-Ion Batteries – Battery University). But you won't hurt anything if you don't.
