Electric vehicles, hybrids, and conventional ICE vehicles
Proven technology ensures optimal performance in all driving conditions
A premium AGM battery developed with the world’s first AGM technology and 80 years of expertise.


Hankook & Company’s Automotive Supreme AGM series is a premium battery
trusted by leading global OEMs. It is engineered to meet and exceed the demanding
requirements of advanced start-stop vehicles and xEVs equipped with cutting-edge electronic
systems. The AGM lineup offers tailored solutions for a wide range of applications
from standard and high-temperature durability specifications to xEV and auxiliary power support.
Changes in usage environments defined by increased starting frequency and always-on electrical loads.
Modern vehicles continuously consume power
due to features such as black boxes, navigation systems, ventilated seats, and heated functions,
even when the engine is off.
Additionally,ISG systems further increase starting frequency, placing additional load on the battery.
Under these conditions, conventional flooded batteries have limitations in maintaining durability and performance.
