I wonder how long the airlines will be able to stand what was already an apparently abnormally high battery replacement rate prior to the fire/overheats.
The cause of those replacements was predominately due to the battery being too deeply discharged by ground staff using it during operations like refueling and tripping safety systems.
Boeing is raising that limit so I guess that means when the battery cuts-off, it will be at a charge level that will allow the onboard charging system to bring it back up and it will no longer need to be removed.
Here is a YouTube Clip of part of the Boeing presentation on the changes they are making to the battery system -
