Group 34/78 Battery

Shop our selection of Group 34/78 car and truck batteries, available in both Flooded and AGM options to suit a wide range of vehicles. With high Cold Cranking Amps (CCA), these batteries provide reliable starting power in cold weather and dependable long-term performance. Whether you’re replacing a standard flooded battery or upgrading to an AGM for improved durability and maintenance-free operation, we have the right Group 34/78 battery for your vehicle.

Group 34 and Group 78 batteries share similar dimensions, and a Group 34/78 battery is designed to fit applications requiring either size. These dual-terminal batteries feature both SAE top terminals, like a Group 34 battery, and 3/8″ side terminals, like a Group 78 battery, providing added installation flexibility and broad vehicle compatibility.

Please note: In some vehicles, the battery tray or hold-down bracket may be too tight to accommodate a dual-terminal Group 34/78 battery. In these cases, a dedicated Group 34 or Group 78 battery may be required. Always verify fitment before purchasing.
