I don't know if this will help, but if you know anyone in engineering 
at a radio or TV station you might ask if they have any UPS's they 
are going to get rid of (trash).  I have two 1500 VA rack mount UPS 
sine wave units that a local station was going to trash.  The chief 
told me that when the batteries get old they simply replace the 
entire unit.  Mine have been running my two DATUM GPSA units for 
about 8 years and I've only had to replace the batteries twice; once 
when I got the units and one other time about two years ago.  They're 
still going strong.  They're pretty close to my HF  radio and I have 
not experienced any RFI from them.

I have decided I'd like to get a UPS to put on the rack containing my 
Thunderbolt, the laptop that runs Lady Heather, and frequency counter.
Has anyone had bad experience noise wise with the APC brand units 
like are available on Amazon and at Staples? I'd like to get one that 
doesn't generate lots of RFI. Thank you.
