Over 30 years of battery expertise and a commitment to our customers and quality.


Delkor Co. Ltd was established in 1985, as a joint venture with GM, the biggest automotive company in US. In 2010, with the goal of supplying unrivalled-quality automotive batteries, we joined the world’s largest automotive battery enterprise, Clarios, formerly Power Solutions.

Today, we are known as Clarios Delkor Corporation. We supply maintenance-free (MF) batteries to global automotive companies, including Hyundai, Kia, Toyota, Honda and Nissan, to name a few. We also extended our battery provision to industrial, commercial, agriculture machinery, deep cycle and marine applications.

Giving our customers the best is the motivation behind our breakthroughs. Enjoying quality, products and service that surpass expectations – we believe, The Power Is Yours.
