May 29, 2025: Asia-based lead battery giants Leoch International and GS Yuasa are strengthening ties and discussing plans to develop and market their respective brands worldwide.
Leoch chairman Dong Li led a team of senior company executives for partnership talks at Yuasa’s Kyoto HQ on April 28, Leoch has now revealed.

The talks took place less than two years after Leoch signed an agreement to acquire controlling stakes in two China-based lead battery firms owned by Yuasa — Tianjin GS Battery and Yuasa Battery Shunde.

Dong Li said the visit underscored a deepening partnership between two global battery pioneers, which he said was uniting decades of innovation, strengthening collaborative R&D, and aligning strategic visions to accelerate breakthroughs in energy technology.

At Yuasa’s automotive battery production facility in Kyoto, the Leoch team saw advanced processes including plate manufacturing, automated assembly, and intelligent quality inspection.
Both sides said they would jointly expand their battery brands in the transportation power market and target high-growth sectors including electric vehicles plus energy storage systems.
Batteries International reported last month that Leoch had posted a near 20% boost in topline growth in annual results for 2024, driven by robust sales of the group’s mainstay lead battery technology across global markets.

Earlier this month, Yuasa said battery sales had driven a rise in its operating profit over the past year, reporting that operating profit before amortization and goodwill was up 20% to JPY50 billion ($341 million) for the year ended March 31 compared to the previous financial year.
