It uses an EFB (enhanced flooded) battery, typically on stop-start trims. An EFB or AGM in Group 48 is the correct replacement. A plain flooded battery is not recommended. The 660-760 CCA rating is on the higher end, typical of larger engines and trucks, and it matters most for reliable cold-weather starts. Group 48 defines the case size and terminal layout (standard-terminal layout), so any reputable Group 48 battery will fit the tray and connect correctly. Some trims or engines use Group 47 instead, so always confirm against the label on your current battery.

Where to buy a Group 48 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:
