GS Yuasa Battery

What GS Yuasa Battery does

GS Yuasa Battery Ltd. (株式会社ジーエス・ユアサ) is a Japanese battery manufacturer formed from the 2015 merger of Japan Battery (founded 1917) and Yuasa Storage Battery Manufacturing (founded 1918). The company designs, manufactures, and sells lead-acid and lithium-ion batteries across four primary product lines: automotive batteries (passenger cars, commercial vehicles, and aftermarket replacement, including the ECO.R ENJ and ECO.R Revolution V2 series optimized for idling-stop vehicles), motorcycle batteries (where it holds global No.1 share), agricultural and construction machinery batteries, and lithium-ion batteries for electric vehicles, plug-in hybrid vehicles, hybrid vehicles, and industrial energy storage systems. Core technology rests on over a century of lead-acid battery expertise, including the proprietary 易反応性鉛粉製造法 (Easy Reactivity Lead Powder Manufacturing Method) developed in 1920 and still in use today, combined with 20+ years of lithium-ion R&D for electrified mobility applications.

The company operates as a publicly traded corporation on the Tokyo Stock Exchange (ticker 6674) and runs an integrated business model spanning OEM supply to virtually every major Japanese automaker — Toyota, Nissan, Honda, Mazda, Mitsubishi Motors, Subaru, Suzuki, Daihatsu, Isuzu, Hino, Mitsubishi Fuso, and UD Trucks — and motorcycle OEMs (Yamaha, Kawasaki). Aftermarket and replacement demand is served through a domestic network of certified Batterymaster dealer stores (バッテリーマイスター認定店), supported by an online dealer locator and battery fitment search tool. Revenue is generated through hardware sales across automotive, motorcycle, industrial, and emerging electrified-vehicle segments; pricing is not publicly disclosed, but warranty terms extend to 24-month/40,000 km coverage on selected product lines.

GS Yuasa holds the No.1 position in the Japanese automotive aftermarket/replacement battery market and ranks No.2 globally in automotive lead-acid batteries. The company employs over 10,000 people and is headquartered in Kyoto. Recognitions include the IEEE Milestone (2014) for contributions to lead-acid battery development and the Ichimura Industry Award (2014) for ISS battery innovation. Recent operating signals include a June 2026 price revision on automotive lead-acid aftermarket batteries and an ongoing recall of SE-51/SE-50 battery chargers.
