What puzzles me about these battery events is why they happened when they happened? And why now for, apparently, the first time?
FYI, the ANA aircraft (Line number 9, first flight Jan. 9, 2011) and JAL aircraft (line number 84, first flight Dec. 7, 2012) came off the production line almost two years part. Line Number 1 first flight was Dec. 15, 2009.
My guess: If there aren't serious design problems, is that there are defectively manufactured electrical component(s) involved.
