Japan clears battery maker

Japanese investigators studying the potentially flammable batteries that have grounded Boeing’s 787 fleet wrapped up an on-site inspection at the batteries’ manufacturer Monday and said they would continue their inquiry at a maker of a device that monitors the batteries.

Japan’s Ministry of Transport said that for now, investigators had found no quality control problems during an eight-day inquiry at GS Yuasa, the maker of the lithium-ion batteries at the center of the inquiry.
