Delkor® batteries have been selected as the top automotive batteries for the 18th consecutive year in the 2023 Korean Standard Quality Excellence Index (KS-QEI).

The Korean Standard Quality Excellence Index is a quality measurement model jointly developed by the Korean Standards Association (KSA) and the Korean Society for Quality Management (KSQM), reflecting customer satisfaction with product and service quality and the characteristics of various industries.

In this year's survey, Clarios Delkor Corporation received the highest score in the comprehensive evaluation in the automotive battery industry for six usage quality criteria (performance, reliability, durability, usability, safety, accessibility) and three emotional quality criteria (image, cognition, novelty). They have maintained their position as the number one choice since 2006.

Delkor®, a brand of Clarios, a global leader in low-voltage battery manufacturing, supplies a wide range of high-quality vehicle batteries. This is achieved through advanced technology, state-of-the-art manufacturing methods, continuous research and development, and rigorous quality control at every production stage.

He also expressed his pride in the journey of cooperation with customers and suppliers that allowed them to achieve 18 consecutive first-place awards in the automotive battery sector with the efforts they have accumulated to date.
