HI RICK

Everything Karait said is correct. I believe that he is one of the contributors to this site that does know his stuff.

On a practical issue

Do you have somebody to assemble the batteries when the cells arrive

If they are not really familiar with the process ensure that the cell terminals are of the Screw On type ( Easier )

Individual cells may be shipped dry so you may need acid when they arrive.

You will also need to dispose of the old cells in an approved manner
As an importer this will become your responsibility.

None of this is complicated. Just needs to be done
