That makes sense. Thanks for pointing that out I did not realize that.

I'd look into it further, but ironically, the local power company has scheduled maintenance coming up soon, and I am typing this on a machine with a Tripp Lite UPS that doesn't play well with NUT. Should have more time later today or this week.
>> At first after installing the debian nut packages with apt-get and setting up the config files I had to setup a systemd service to exeu "upsdrvctl shutdown" on shutdown or else the ups would not turn off at all. Now after setting up that service is when I discovered the issue, that the ups does not delay in shutting down.

Okay, I will check the bug trackers. Also I will setup a fresh Debian 9 
install on another system and see if the problem still happens.

Thanks, Good luck with the power company. :)
