system down after the UPS reports a low battery. Your UPS may or may not allow
that threshold to be configured, so there are several other options if you want
to shut down after a specific time on battery, or when other conditions are
reached.

These are the voltage thresholds for the UPS, so theoretically the UPS will send
the LB signal when the battery voltage goes lower than 10.40 Volts.

Also, if battery.charge works, you can use "ignorelb" if you want to
shut down at another level of charge:

These timers are in seconds. You will want to verify this, but according to
those values, the UPS will shut off its output 30 seconds after the shutdown
signal (so you need to make sure that your OS shutdown takes less time than
that).

Does "upsrw -l advice" show anything?

$ upsrw -l advice
upsrw: invalid option -- 'l'
Network UPS Tools upsrw 2.7.2

usage: upsrw [-h]
       upsrw [-s <variable>] [-u <username>] [-p <password>]
<ups>

Demo program to set variables within UPS hardware.

  -h            display this help text
  -s <variable>	specify variable to be changed
		use -s VAR=VALUE to avoid prompting for value
  -u <username> set username for command authentication
  -p <password> set password for command authentication

  <ups>         UPS identifier -
<upsname>[@<hostname>[:<port>]]

Call without -s to show all possible read/write variables.
