Eaton UPS is initiating a shutdown immediately upon loss of input power (alien.top)

When I unplug the input power to my Eaton UPS, I immediately get the notification emails for "Sequential shutdown scheduled" for Primary, Group 1, and Group 2. A few moments later everything shuts down. I can't figure out why it's shutting everything down immediately.

I'd like for Group 1 and Group 2 to be shutdown when the battery is under 80%, and primary shutdown when the battery is under 10%.

Here's the configuration I'm using: https://files.fletchowns.net/u/eaton_config.png

What am I missing here?

Are your batteries toast? Verify if you don't know. I've only seen that when the batteries are well past expiry, it's literally just the batteries running as long as they can.

The standard SLA batteries typically put in UPSs are meant to be replaced every 3 or 5 years, LiIon typically will last roughly twice that or more with proper care.
