[Nut-upsuser] Overriding battery.runtime.low

I have an APC BR1500GI and want to run my devices for the longest possible
period. Consequently I want to use the battery.runtime.low setting, sufficient
to allow my devices to shutdown. The APC has a setting of 5 minutes for this
purpose but I want to change this to 10 minutes, so have added the
?override.battery.runtime.low = 600? setting to the ups.conf file. However, this
override doesn?t appear to be causing the NUT setup to initiate a shutdown.

Does the ?override.battery.runtime.low? work for this purpose or does it just
change the value being displayed by upsc? If it?s the latter, is there a way to
achieve the override for the low battery setting? For testing purposes I changed
this value to ?2500?, switched off the mains, and monitored the
?battery.runtime? value. It dropped below ?2500? (and remained there) but the
?battery is low? message was never generated.

Required information:

                OS: Linux **** 5.4.83+ #1379 Mon Dec 14 13:06:05 GMT 2020 armv6l

                NUT installation: package

Thanks.
