lack of training

That would be an explanation for some batteries, but not for 150. After the first unplanned changes normal people learn from mistakes. Is the true problem masked by some of these causes as you describe them?
And are you saying, that the battery changes have nothing to do with the known two incidents from ANA and JAL?
Boing and the 787 operators loose big money, and a lot of highly qualified people are looking into the problem. There are some possibilities imho:
1.) they know the cause already, but there is no quick solution at hand /approved by FAA and therefore there is no need to tell anybody, or
2.) they are looking in the wrong corner, are still looking at the symptoms and have´nt found the causes yet.
If an easy work around (like diconnecting from chargers) would be practicable, we would see it already. They checked the batteries, they checked the chargers, they are checking the PCB´s. They have hundreds of used and new batteries available for testing, and the grounded aircrafts as well. They came out with nothing until now.
Whatever we will see, it will be very interesting.
