Electrical Batteries make use of sulphuric acid. Sulphuric acid on storage in plant and transporting via pipelines and tankers causes corrosion of the material of construction of the equipment, thereby carrying some amount of iron with them. How would this affect the batteries?

Concentrated sulfuric acid (>98%) is transported in tankers. 98% Sulfuric acid does not cause corrosion. Only if water is present, the acid causes corrosion. Battery acid , which is dilute, is transported in polythene carboys or made on the spot by diluting concentrated acid in polythene carboys.

That is fine. I'm asking from the point of view of an acid manufacturer. Say if by chance corrosion takes place and 98% H2SO4 acquires some iron salt, and the acid is to be sold to as battery acid by some other vendor, is it likely to cause problems in the battery? Will there be any effect on the reaction taking place?
