Botnic gives a good simple answer. Here is the additional information that makes the answer 'complicated'
I assume that you are using lead acid battery, but the same applies for lithium ion. They use a constant current-constant voltage charge scheme which means that it's not a simple calaculation.
So a 600Ah battery charged at 600 amps will take longer than one hour to charge. Lead acid are even more complex because as they get fuller, they get less efficient so that for every amp you put into the battery, only 60% or less actually goes to the charge, the rest is wasted.
For a lithium ion battery you take the expected time to charge multiply by 1.4. So a 600Ah battery charged at 600amps, would take 600/600 × 1.4 to charge. The 1.4 is for the constant voltage stage of charging, which is different than the 1.4 that is used in the first answer, which was for ineficciencies. A lead acid battery is similar, but takes a little longer because of the inefficiency as it fills up.
So with this info, aply to your numbers.
