It comes with a standard flooded battery. You can usually step up to an AGM in the same Group 34 for longer life, but it isn't required. The 650-800 CCA rating is on the higher end, typical of larger engines and trucks, and it matters most for reliable cold-weather starts. Group 34 defines the case size and terminal layout (standard-terminal layout), so any reputable Group 34 battery will fit the tray and connect correctly. Some trims or engines use Group 25 instead, so always confirm against the label on your current battery.

Where to buy a Group 34 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:
