[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.
