In a Classification 1, Division 2 area, can batteries be installed and operated, or do they need to be issolated? I can't find anything about it in the NEC. I assume they are ok, since they do create a Class 1, Div 2 area under the right circumstances.
By the way, the system voltage is 12V so there is not a large potential.

Class 1, Div 2 is an area where ignitable concentrations of flammable gasses, vapors or liquids are NOT likely to exist under operating conditions.
Battery rooms, where hydrogen is evolved must be fitted with an exhaust fan at the highest point in the room for it to comply with Cl1, Div 2 classification.
Now to comply with the requirement, the hazardous area MUST contain some type of exhaust system if it is in a room or if outside in an open area it will be OK to install and operate a battery system.

I would think that you would want to keep those batteries out of the hazardous areas because hooking them up or disconnecting them might cause a spark. And by definition, there is a possibility of having an explosive concentration of your hazardous substance in a classified area, right?

Does the NFPA code covers a recommendation about the Internal separation wall between the battery room and the rest of the building, shall be fire rated for how many hours ??, knowing that the battery room is a subsidiary of a steel warehouse for power system UPS
