Yuasa Climbs as Boeing Said to Prepare 787 Battery Fix

GS Yuasa Corp., the battery maker for Boeing Co.’s grounded 787s, rose the most in more than a year as the planemaker is said to ready proposed fixes to ensure the jet’s batteries won’t damage the aircraft or emit smoke.

Yuasa rose 8 percent, the most since November 2011, to 352 yen at the close of trading in Tokyo. Today’s gain erased the Kyoto-based battery maker’s share-price drop this year.

A Boeing team is scheduled to meet in Washington with the U.S. Federal Aviation Administration Feb. 22, said the people, who weren’t authorized to discuss the session and asked not to be identified. The plan includes a harder battery case and a venting mechanism for fumes, one person said.

U.S. and Japanese authorities are investigating the cause of a battery fire on a Japan Airlines Co. plane last month, followed by smoke that caused the emergency landing of an All Nippon Airways Co. flight and led to Boeing 787 Dreamliners being grounded globally from Jan. 16.

Tsutomu Nishijima, a Kyoto-based spokesman for GS Yuasa, which makes lithium-ion batteries for the 787, declined to comment on the battery fixes.
