Hello, I have a 1920w Tower UPS that didn't come with any batteries. Should the UPS power up and show display even when there are no batteries present? Thank you.
No, the main battery is required for operation. The EBM is optional and can be hot swapped, but the system will not function without the primary battery installed.

That's awesome to hear... because I got 7 of these things at an auction and I'm plugging them in and none are showing display. I was wondering if these could all really be bad so that's reassuring. Thanks for getting back to me, I really appreciate it
The issue you are going to have is building the battery pack. The UPSs do not take an off-the-shelf battery pack that plugs right in. If you had a dead battery pack it is easy to rebuild them. Did any of them come with battery packs installed?
