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 550-710 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 24F defines the case size and terminal layout (standard-terminal layout), so any reputable Group 24F 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 24F 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:
