Do the math, StoneDeaf. 600 mah battery pack, if you use a 50 mah charger, that's 600/50 = 12 hours for a full charge from completely discharged with that charger. If you have a 1000 mah battery pack, same charger will be 1000/50 = 20 hours charge time from fully discharged.

There is a fudge factor there, allow about 10 to 20% more time to cover losses due to heat, and so on. But, that's a pretty good rule of thumb. Overnight will charge at full capability till full, then trickle charge to maintain once it's fully charged. So, if you suspect you used, say 300 mah of a 600 mah battery, overnight charge will produce a fully charged battery in 6 hours then leaving on charge for the rest of the night no matter what with that charger will definitely produce a fully charged battery.
