GS Yuasa Corporation (株式会社ジーエス・ユアサ コーポレーション Kabushiki-gaisha GS Yuasa Kōporēshon ?) is a Japanese company that makes lead acid automobile and motorcycle batteries.

GS was established in 1917[2] and is an abbreviation comprising the initials of Genzou Shimadzu (the founder's name of Japan Storage Battery). He was also the founder of Shimadzu Corporation.

Yuasa's history in the U.S.

Yuasa formed a joint-venture company with General Battery Corporation in 1976. Yuasa manufactured its first battery in 1979 in the United States, producing standard conventional and Yumicron 12 volt batteries.

Yuasa developed a maintenance free and gas recombination battery for powersports vehicles in the early 1980s, and the first AGM battery, intended for ATV applications.

Yuasa was sold by General Battery Corporation to Exide in 1987 to form Yuasa/Exide Battery Corporation. Yuasa/Exide then purchased Exide's Industrial Division to become Yuasa Inc. in 1991.

After selling off its industrial division to Enersys in 2000, Yuasa Inc. changed its name to Yuasa Battery Inc. In 2004, Yuasa Japan merged with Japan Storage Battery to form GS Yuasa Corporation.

Now the top power sports battery producer, Yuasa provides nearly 90% of the batteries used in power sport vehicles in North America.[3] The parent company in Japan was linked to faulty electrics used in Boeing's 787 Dreamliner plane.[4] The electrical battery control system was made by Thales Group which also selected GS Yuasa.[5][6]All Nippon Airways (ANA) had replaced 10 batteries (of 17 planes) while Japan Airlines (JAL) had replaced "several" on its 7 planes, before recent mishaps.[7] As of January 29, 2013, the Japan Transport Safety Board has approved the Yuasa factory quality control and continues to investigate the damaged battery of the ANA 787.[8][9][10] Meanwhile, the American National Transportation Safety Board continues to look for defects in the Boston JAL 787 battery.[11]
