But for the starter, it is a myth because the starter power is constant. meaning if 1sn is sufficient 1sn is sufficient, getting 8d will not make a difference to the starter except for the number of times the battery can start the engine without charging.

This is a good discussion and I'm learning a lot that also includes the reply of glenn manikis

By the way, lead is 100% recyclable and would not make any difference if the lead is freshly mined under a certain mountain or recycled from other components, it is the design, manufacturing process and other stuff that makes a difference to prevent deterioration of components inside the battery.

Thank' s to your reply and to glenn manikis, and this become a good discussion and I'm learning a lot.

PASS/FAIL: BATTERY TESTING & SERVICING by BY BOB PATTENGALE

In many cases when a battery fails, the recommended exact-match battery may not be available, so a substitute will be installed to get the customer going. If the battery selected is smaller—less cold cranking amps (CCA)—than recommended, an overcharging issue may occur.
If the battery selected has a higher CCA than recommended, an undercharging issue may occur. In either case, this may reduce the life of the battery and create other electrical issues. In the case of the starting system, a higher capacity battery may be the cause of a starter that fails prematurely or causes mechanical damage at the pinion or flywheel ring gear.

may I know the take of our experts here...
