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 200-350 CCA rating suits this vehicle's modest starting demands; match it or go slightly above. Group U1R defines the case size and terminal layout (reversed-terminal layout (r)), so any reputable Group U1R battery will fit the tray and connect correctly.

Where to buy a Group U1R 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:
