It comes with a standard flooded battery. You can usually step up to an AGM in the same Group 47 for longer life, but it isn't required. A 600-680 CCA rating is typical for this class. Matching or slightly exceeding the OEM figure is fine; going below it risks hard starts in winter. Group 47 defines the case size and terminal layout (standard-terminal layout), so any reputable Group 47 battery will fit the tray and connect correctly. Some trims or engines use Group 35 instead, so always confirm against the label on your current battery.

Where to buy a Group 47 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:
