In Karachi an unused (torn packing) OE positive side terminal for japanese cars used to cost Rs 100/- in 2005. Solid heavy duty items usually found on german cars and heavy diesels used to cost Rs 200/-
I used to charge Rs 200/- for a casted terminal - the wire was put into the hot metal and the metal cooled around it making one big solid connection. for the starter, the stud sticking out from it would be used to tighten the accessory wiring.
I also made negative terminals from copper pipe shaped to the battery post. Looked better than OE.
