How long will it take to charge a Traxxas "series 1" 6 cell NiMh at 1.2 amps?

How many mAh's do the battery have? I couldn't find it anywhere.

Say it has 2400 mAh's (wild guess) it will take two hours to charge with a charger that put out 1,2 A's, putting in to the battery 1,2 A's pr hour. If it is 4800 mAh's it will take 4 hours to charge (theoretically)

1.2 amps is 1200 mah (per hr)

So it will take around 45 minutes.
