Admittedly, that did make me chuckle.
But in all seriousness it seems that the operating environment specified was too narrow - after all, if the units hadn't passed Boeing's and the FAA's requirements and testing then they wouldn't have been fitted to the aircraft. Conditions faced on the line seem to have been outside the boundaries of the original spec.
The point being that no matter which company was contracted to develop and build the battery systems, if the spec was the same then they'd have still had the same problems vis. battery fires.
