thanks to send me a verbose startup trace (ie "mge-shut -DDDDD ..."),
and 2 upsc outputs (one when OB and one when OL).

I wonder if this issue isn't due to a low charge on output, but it's
however strange. Note that you can meanwhile use the upssched mecanism
to force the shutdown on a battery.charge or battery.runtime (or
whatever) criteria.

If you need, I can provide such a script...
