I would think a 2 year old OEM battery would have some sort of warranty for it still. I bought a couple of the top post batteries at Costco for a 2014 Chev. diesel for about $117 each and they have a 42 month full replacement warranty and are Interstate batteries. The Kirkland batteries in another were replaced with the side post and they had a 100 month warranty so got about $25 off the new battery also and those were just under $100.
