It comes with a standard flooded battery. You can usually step up to an AGM in the same Group 51R for longer life, but it isn't required. The 410-500 CCA rating suits this vehicle's modest starting demands; match it or go slightly above. Group 51R defines the case size and terminal layout (reversed-terminal layout (r)), so any reputable Group 51R battery will fit the tray and connect correctly. Some trims or engines use Group 47 instead, so always confirm against the label on your current battery.

A car battery is heavy and expensive to ship, so buying in person (Walmart, Costco, or a local auto-parts store) often beats online once you count free installation and the core-charge refund on your old battery. To compare prices and reviews online:
