This vehicle ships with an AGM battery from the factory, which is common on models with engine stop-start. Replace it with an AGM of the same group, not a standard flooded battery, or you risk shorter life and dashboard warnings. 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.

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:
