Nut upsuser - Aug 2021 - [EXTERNAL] CyberPower CP625HGa shuts down 3 watt load in 2 minutes

Greeting Roger;

And the battery is still at 98%. The load is a 5 watt supply running an 
r-pi-4 with a mesa 7i90 interface card.

How can one change that, it ought to run that 3 watt load for hours.

Cheers, Gene Heskett

When I want to run a UPS down while I'm testing, I plug in a high-wattage
lamp on a spare outlet.

Hello Gene, good to hear from you.

Agreed.  Whats wrong?  The first thought is for the battery.  How old is it? 
Really ancient batteries behave as you describe.

If it's not the battery then we need to look at the configuration.  Do you
use
the default behaviour of upsmon which is to shutdown on status LB?

What does command ? upsc <ups> battery.charge.low ? report?

test the battery outside the UPS. it could be an old enough battery 
unable to really retain energy. It reports a voltage high enough to make 
a voltmeter believe it is charged but in fact it does not hold the charge.
