AGM won't spill , vent or leak acid.
Lots of electronics sitting next to the battery , worth a lot more than you can save on a cheaper battery.
I've used Carquest , know Napa also carries AGM, both at far better price than dealer.
Original in my 2008 ( out of factory in Alabama) was AGM made by EastPenn.
Carquest replacement is also EastPenn.
Interstate is also available here.
AGM is one type of VRLA ( other being Gel) ; VRLead Acid should not to be confused with Flooded Lead Acid ( cheaper ) which will spill/leak .
