I got around to unplugging my UPS and I found it doesn't last nearly as long as
estimated.
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.
