WSJ article on Dreamliner's defective battery
Boeing's really struggling with this. The Dreamliner problems go beyond "teething" issues for brand new types of aircraft.
I'm not an engineer, so can someone explain why swapping the defective battery with a proven legacy battery (such the types used in the 777 or 737) would be so difficult? Obviously, there are different electrical system demands on a Dreamliner, but a battery problem seem like a pretty modular and easily fixable recall, as opposed to say a hydraulic system or landing gear defect.
In all of the incidents, none of the other electrical system components were malfunctioning (charging unit/surge protector/etc.). One commentator on that article speculated that this sounds like a battery-supplier quality control issue versus an electrical system design issue.
