It depends on how fast you are doing it.

You're asking a similar question as this: How long does it take to get from Cleveland, Ohio to Surprise , AZ.

ps. I se below and above that there's some question as to the type and number of cells and the voltage. Fortunately none of this matters (for your question). Only the capacity and charge current matters.

Are you sure that it is a 2-cell battery? 8.4 V NiMH are usually 7-cell packs. 2-cell Lipo batteries are 7.4 volts. Without knowing exactly what type of battery you have, it's difficult to say how fast it can be charged. If you check the specs and post back, I'm sure you'll get a good answer.

A two cell LiPo is 8.4 volts fully charged which I assume is what you have. If so, and charging at the recommended 1C, it will take about an hour and 15 minutes to fully charge an empty battery. A good charger starts off at less than the 1C setting and then, as the battery approaches full charge the current tapers off; that is why it takes more than an hour at 1C.
