NTSB: Excess battery voltage ruled out in 787 fire
Investigators have ruled out excess battery voltage as the cause of a Jan. 7 fire onboard a Boeing Co. 787.
The lithium-ion battery at the center of the investigation was not overcharged, the National Transportation Safety Board said in a statement Sunday. The NTSB has not determined the cause yet in that 787 fire.
