During an early inspection of the 787 in Takamatsu by Japanese officials, the battery’s electrolyte had leaked from the lithium-ion battery.
The charred insides of the battery show the battery received voltage in excess of its design limits.
In October 2011, the FAA issued an emergency order requiring lithium ion batteries in 42 Cessna Citation CJ4 to be replaced with nickel-cadmium or lead-acid batteries, after a connection with a ground power station led to overcharging and a fire.
Wait…was this human error and not battery error? Or a combination of both?
