Lot of two Dell APC UPS 3000VA battery backup units with one empty RBC43 battery tray. Battery tray has all wires, just needs new SLA batteries. One unit has the default twist-lock power connector, the other was hard-wired into building and will need a power connector or to be hard-wired again. Faceplates included. No rails included. No optional network management cards, but can use stuff like AP9630, AP9631, AP9640, AP9641. These are in good working condition, they just need new batteries. We downsized our lab environment and no longer need these.
