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. The 850-925 CCA rating is on the higher end, typical of larger engines and trucks, and it matters most for reliable cold-weather starts. Group 49 defines the case size and terminal layout (standard-terminal layout), so any reputable Group 49 battery will fit the tray and connect correctly. Some trims or engines use Group 95R instead, so always confirm against the label on your current battery.

Where to buy a Group 49 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:
