According to the 2025–2026 China UPS Supporting Lead-acid Battery Market Report released by ICT Research, KSTAR’s valve-regulated lead-acid (VRLA) batteries for UPS systems have maintained the No.1 position among domestic Chinese brands by sales revenue for 13 consecutive years, further strengthening KSTAR’s leadership in the backup power industry.

Intelligent Manufacturing and Innovation Build a Strong Quality Foundation

Driven by intelligent manufacturing and continuous innovation, KSTAR has established a vertically integrated production system through its wholly owned subsidiary, Jiangxi Changxin Jinyangguang Power Supply Co., Ltd. The company has built a complete manufacturing chain covering electronic component production, battery assembly, performance testing, and standardized packaging, enabling independent control throughout R&D, manufacturing, and supply processes.

With advanced automated production equipment and five intelligent production lines, KSTAR’s battery manufacturing facility achieves an annual production capacity of 3 million kVAh, supporting large-scale project requirements across industries.

From raw material selection to final product inspection, KSTAR applies strict digital quality management through MES production systems and digital twin-based quality control platforms. Using high-purity lead materials and automated manufacturing technologies, KSTAR continuously improves grid structure stability, production consistency, corrosion resistance, and overall battery lifespan.

KSTAR VRLA batteries have obtained certifications including TLC, CE, and UL, meeting stringent requirements from industries such as finance, telecommunications, and power infrastructure.

Advanced Technologies Enhance Safety and Performance

To address common challenges such as leakage risks, performance degradation, and operational safety, KSTAR has developed proprietary technologies that enhance both reliability and battery performance.

The innovative anti-slip and acid-resistant protection pad design helps prevent battery movement and acid leakage, improving operational safety during long-term deployment. Meanwhile, optimized grid structures improve current conduction efficiency, reduce energy loss, and effectively extend battery service life.

Comprehensive Battery Solutions for Diverse Applications

Based on diverse industry requirements, KSTAR has developed a comprehensive VRLA battery portfolio supporting critical power applications in sectors including finance, telecommunications, government, and digital infrastructure.

For high-density computing infrastructure and scenarios requiring short-duration, high-power backup, KSTAR provides the GFMHR High Rate VRLA Battery Series. Designed for demanding backup applications, the series features:

• High-rate discharge capability for critical loads

• Gas recombination technology with maintenance-free operation

• Up to 12 years floating design life

• Wide operating temperature range from -20°C to +50°C

• Enhanced compatibility with UPS systems

By working seamlessly with UPS systems, KSTAR batteries help ensure continuous power availability during grid interruptions, reducing risks such as equipment downtime and data loss in critical infrastructure environments.

Beyond standalone battery products, KSTAR also provides customized “UPS + Battery” integrated solutions based on project power requirements, installation conditions, and budget considerations. With independently developed core components, unified monitoring, battery management, and complete accessory solutions, KSTAR helps customers simplify procurement, deployment, and long-term operation and maintenance.

Building a Reliable Power Foundation for Digital Infrastructure

With more than 30 years of experience in smart energy solutions, KSTAR continues to strengthen its expertise in UPS and backup power technologies. According to data from CCID Consulting and Omdia, KSTAR has ranked No.1 among domestic brands in China’s UPS market by sales volume for 26 consecutive years and remained among the Top 5 global UPS suppliers for six consecutive years.

Looking ahead, KSTAR will continue investing in battery technology innovation and intelligent manufacturing capabilities, delivering safer, more efficient, and longer-lasting backup power solutions to support the development of global digital infrastructure.
