How old are the batteries?

"Shutting down" or "turning off" a UPS means turning off the power outlets to 
the Pi. The instruction manual at 
https://www.montersi.pl/pliki/or600elcdrm1u-instrukcja-25681.pdf says

  Self -Test    Yes
  Auto-Charger  Yes
  Auto-Restart  Yes

so it looks as if the UPS Unit should be able to turn off the power outlets and 
turn them on again when wall power resumes.  Do you hear a "clac" from the 
internal relays when the UPS turns off the power outlets?
