Any suggestions, please?

Too bad the old, flaky and dangerous electrical wiring/installation 
where I work still fries both the UPS and the boxes connected to it. 
Okay, not fry, but the UPS' battery life was sure cut in half a few 
times and the new UPS still cannot protect the boxes when there is a 
momentary split second blackout.
