Standard vs AGM will be set when you register the battery. If you make a change from one to the other, you must get it registered soon. The car charges the two types differently. I had my battery replaced just before my warranty ran out. They put an 80AH 800A AGM battery in mine
I will go back to 90AH when this one goes.
