We have been doing some work in the warehouse at work and a couple weeks ago the electric company turned on a new compressor. At that moment, a section of the office area had their lights flicker and 5 workstation UPS's started beeping. We spent the next couple hours trying to get these UPS's back to working properly, but all of them would automatically kick over to the battery and continue to beep when we plugged it in. In the mean time, we plugged the PC and Monitor into the "Surge Protection Only" outlets, bypassing the "Battery Backup" outlets and powered off the UPS's. We ordered new batteries, thinking that might be the issue, but the same thing happened with brand new batteries (yes, we charged them up first).

Each device has a feint, but distinct burnt electronics smell, so now we are thinking all 5 devices are fried beyond repair. Is there a way to test this, or repair a fried UPS?

It's possible the units took some sort of surge though unfortunately it's had to know for sure. Depending on the issue, it's possible it could be fixed but since these units do not have user replaceable parts(except for the batteries), I can't offer much as far as getting it repaired.
