I would not be sure the resolution is fixed. Older versions of FW weren't as good at monitoring the passive controller HW. If you can, during a maint window I would fail back to that controller to be sure that battery is actually a set of capacitors. Which can leak, and fail.
I just encountered the same problem "C2F power module has insufficient hold time", indicating Battery: Failed on active controller. Then I accidentally discovered a possible solution is to press Restart, ie, switching the controllers (active>passive). After the switch over is completed, the failed battery return to GOOD!!! No idea why this fixed the problem, but no harm to try if you guys encountered the same battery failed problem in the future.
