I think you figured it out: the UPS probably has another low-battery threshold, below which it will not start back up until it charges some more. If the UPS shuts down at 10%, and the power comes back briefly, there would be a period of time where the computer is powered, but NUT hasn't started.

Usually, this is shown as the "battery.charge.restart" variable, but  I have a feeling that this is one of the APC Smart-UPS models that has a lot more settings available via other protocols.

Here is some more background info:


What does 'lsusb -d 051d: -vvv' return?
