[Nut-upsdev] Shutdown by battery.remaining or battery.runtime?

See 'man 8 upsrw'. If your UPS supports changing this value, it should be
listed if you run 'upsrw <upsname>'. Most of the time, if it is possible
to change this value, it will be stored in non-volatile memory in the UPS
itself, so you only need to do this once.

If you have any more questions regarding this, please use the nut-upsuser
mailinglist instead.
