What would be the maximum charging current for 2 sets of 600AH batteries from 100 Ampere SMPS type Charger when battereries are fully discharged or half discharged?

Charging current and AH capacity of batteries have only a very loose relationship.
Your best bet is to contact the battery manufacturer and get their charging profile (current vs time) for the battery. Then *follow* it.
More batteries have been destroyed by improper charging than by any other factor ☺

The maximum charging current for any type of lead acid battery is determined by the current limit setting on the battery charger and the internal resistance of the battery.
Higher the Ampere Hour rating of the battery, lower will be the battery resistance. (for a healthy battery)
The current limit function in the battery charger will decrease the charging voltage to the battery and keep the current within the set limit. As the battery gets charged, the current will decrease progressively.
The thumb rule is, set the charging current to 10% of the rated capacity of the battery.

A typical charging rate would be a C/10 rate were C would be the capacity of the battery (600Ah) so you would charge one at about 60 Amps for 10 hours if it was fully discharged.

12 Amps
