I got around to unplugging my UPS and I found it doesn't last nearly

Is the "upsmon[1446]: UPS desktop_ups@localhost battery is low" logged
when "battery.runtime:" = "battery.runtime.low: 120"?
Does any make better batteries that don't go down faster when they get
old?
In my experience batteries die after about 4 years.
No UPS that I owned could tell that the batteries are bad, I find this
when the UPS power is
disconnected and the UPS shuts down soon (often in seconds).
You can test the condition of the battery by periodically removing the
power input and see how long
it actually runs down to, say, 20%.
Vendor software usually has a "test" feature, don't know if nut has this.

It runs down in 10 minutes yet takes a long time to charge to full (it
estimates another 5 hours (it's already been 4 hours)).
I did a test:
$ upscmd -u xxxx -p xxxx desktop_ups test.panel.start
$ upsc desktop_ups
ups.status: OL CHRG
I think it thinks it is ok.
