I agree on the 50 hours. Following equation:

1.5 x Battery Capacity/Charge Current

1.5 x 500/15 = 50 hours.

When I used to charge a lot of NiMh battery packs for amateur radio, I used a timer to cut the charger off after the correct number hours.

If you have a charger with higher capacity for fast charging, just watch for any heat buildup. I have a Fast-Charge charger which has a built in fan to cool the batteries during the charge cycle.
