The 2007 Hyundai Sonata uses a standard 12-volt automotive battery.

The exact group size for replacement is commonly in the 24F family, though some cars may use 24, 34R, or other close equivalents depending on the engine and production date. Always verify with the vehicle's manual or by checking the current battery label.
