Honestly, I always put in an Autozone AGM battery. Why? There are literally Autozones EVERYWHERE, and you get a 3 year warranty. The $hitty dealership batteries are only a year, and I have yet to see one last more than 3 years. If you do go Autozone (or O'Reilly's, since the same company makes both's batteries), the made in Germany H6's are pretty awesome. That's what my mother had in her 2015 JSW before she traded it in for her Tesla (of which I pulled the Autozone and put in a barely able to turn over dealership battery).
