So, I have a hassio installed in docker on my raspberry pi 4B 4gb. In my location we have a power outage about once per two weeks. Sometimes it takes 1-2 minutes sometimes - 1-2 hours. So, Ive bought UPS APC Back-UPS 700, install and configure NUT hassio add-on. Everything works fine till the power outage. Apc_Ups Battery Runtime promises me 13640 s(about 3,8 hours!)
but, APC UPS cuts the power after about 10 minutes from battery. Moreover, when UPS goes online_charging, the battery charge status is 95-96 % !
Please help me to configure my ups right to solve it.
Thanks in advance!

I don’t know about this exact ups, but some models have a setting where they only work as emergency power to ensure proper shut down of all devices.
Typically, when input power goes off, they send a power off-signal to the connected devices and wait for the devices to shut down, and then they cut output power.
So look in the ups manual if there is anything that you need to change on the ups itself to make it run for a longer period on battery.
This is setting in but config files possibly.
For NUT it is possible to set it to shutdown server after XX minutes when power outage detect. I
Also I battery time is based on power draw and battery health so 3hr estimate may be less or more than actual
How do I set NUT to shutdown Hassio after XX minutes? Any guidance appreciated 
Create an automation using the state of sensor.name_status_data as the trigger.
