Boeing had numerous reliability issues with the main batteries on its 787 Dreamliner long before the two battery incidents this month grounded the entire fleet.
More than 100 of the lithium-ion batteries have failed and had to be returned to the Japanese manufacturer, according to a person inside the 787 program with direct knowledge.
“We have had at least 100, possibly approaching 150, bad batteries so far,” the person said. “It’s common.”
The frequency of battery failures reflects issues with the design of the electrical system around the battery, said the person on the 787 program.
