Heavy-duty trucks, buses, and demanding equipment applications
Deliver superior durability and reliable starting performance
The HD AGM battery is designed for environments with massive power consumption,
such as long-haul transport, engine-off heating/cooling, and infotainment.


Hankook & Company’s Heavy Duty Supreme AGM series is a premium battery
engineered exclusively for commercial vehicles, delivering stable performance
even under extreme operating conditions.
With powerful starting capability, ample reserve capacity, and strong deep-discharge endurance,
it provides reliable energy for vehicles
that demand high electrical loads and long-distance operation.
Long-distance transcontinental routes and overnight stays with high power consumption.
Power consumption continues not only while driving,
but also while resting with the engine off—
using air conditioning, electric blankets, and infotainment systems just like at home.
In these continuous charge/discharge situations, standard MF batteries cannot hold up and will fail quickly.
The AGM battery is the most powerful energy source that protects a long-haul driver's life.
