It comes with a standard flooded battery. You can usually step up to an AGM in the same Group 121R for longer life, but it isn't required. The 400-500 CCA rating suits this vehicle's modest starting demands; match it or go slightly above. Group 121R defines the case size and terminal layout (reversed-terminal layout (r)), so any reputable Group 121R battery will fit the tray and connect correctly. Some trims or engines use Group 48 instead, so always confirm against the label on your current battery.
