Exceptionally well maintained Merck surplus.
This is 3-phase, you can not use this on standard 220V. You will know if you need this UPS.
Toshiba G8000 15kVA 3-Phase UPS, 208V input/output, Type C42F3F150XAMBN, internal sealed lead acid batteries, LCD control panel, power factor 0.98 input / 0.88 output, three-phase 4-wire, dimensions 32" x 22" x 63", includes key and batteries, serial number 071004084
We expect the batteries could very well be operable as Merck typically would replace them on a very aggressive cycle. That said we do not have 3-phase service to test these with and have no way of knowing the level of depletion.
