Note: This was tested with a set of brand new batteries and is fully functional. It was also cleaned to remove dust.  This particular unit is sold without batteries but has been fully tested. Battery trays and battery wiring harness is included. There may be varying scratches on the UPS case because they were previously stacked for use with servers, etc. but doesn't affect functionality. 

This is a pre-owned tested Emerson Network Power Liebert GXT3-1000RT120 UPS uninterrupted power supply.  Tested and working properly. Has correct voltage at all outlets. Any questions please ask.
