• High reserve AGM design: The AGM construction provides a stable reserve capacity and reliable starting power for vehicles with moderate electrical load.
• 36 month warranty: The extended warranty period offers peace of mind and shows manufacturer confidence in long term performance.
• Backed by General Motors: Production and support are tied to GM standards, which helps when matching replacement parts for GM vehicles.

Who It's For

The ACDelco Gold 49AGMHR is best for drivers of General Motors cars, trucks and SUVs that require a BCI Group 49 battery or for owners of other makes who need a robust AGM replacement with reliable fit. Mechanics and DIYers who prioritize an OEM-compatible replacement and a clear warranty benefit will appreciate this unit.

This battery is less suitable for vehicles that do not accept Group 49 dimensions or for owners who need extreme deep-cycle performance beyond a high reserve starting design.
