APC Back-UPS ES 8 Outlet 650VA 120V was an upgrade form a similar style 500VA unit I bought something like 5 years ago, which operated perfectly. I decided to upgrade and recycle the whole unit with APC. The return package was thicker than three inches so it couldn't be dropped in a UPS drop box, so I just left it at the UPS store, no problem. Oct 12, 2018 Back-UPS ES 450/550G 'off', then flashing red/green. I bought it from an individual. It was used but looked new, but not sure of its actual history. The serial # is 3B1125X13127. It does have a genuine APC battery installed. The negative wire was unconnected when I opened the box last week when I received it.
