APU operation when (if) it´s battery fails

Hi,

1) From NTSB briefiing: APU stops if it´s battery fails.

I don´t understand why APU stops if it´s yet running (and generating power)

I watched the video and would like a confirmation. (not so sure)

2) Any mention on cell # 6 voltage when shorts initiated BOS event?

This info was lost? (shorts could resulted from improper cell voltage)



PS

One month after BOS event i would expect more info.
