If you have tested it with a known good cable, from a known good source then I would verify the following to see if it allows the UPS to power on.
1.
Verify that the internal batteries are connected.
2.
If an optional EBM is installed, verify that the EBM is connected to the UPS.
3.
Verify that the power input to the UPS has adequate upstream overcurrent protection
4.
Plug the detachable UPS power cord into the input connector on the UPS rear panel.
5.
Plug the UPS power cord into a power outlet.
The UPS front panel display illuminates. The Dell startup screen changes to the UPS status summary screen. The UPS front panel display shows the flashing Standby icon
first of all, sorry me if has past some time since your answer. But I found another UPS (different brand) that was stopped and tried to verify it. Although a different brand what happened with it was that it behaved in the same way, batteries empty and no out power signal. So, as it's a 4 battery unit (DELL unit has 12 units if I recall) I went to look for replacements, but since then I'm still waiting for these new ones from the provider. I hoped to establish some kind of parallelism between both UPSs.
Answering your points:
1. batteries are dead as they have been tested with power tester.
2. we don't have any kind of EBM (if you are refering to an External Battery Module), so there is no way to verify that point. Obviously all remaining points can't be checked.
The question that I'm wondering (that I hope to answer providing new batteries to the abovwe mentioned second UPS) it's if this DELL UPS makes no signal when the batteries are dead in order to avoid the "natural" behaviour of keeping plugged the UPS with dead batteries when the power outage has gone.
Or if there are some points that can be checked to see if the UPS can be used before buying 12 new battery units (limited budget) that would be useless.
Thanks a lot for you time and excuse me for the long time to answer.

Have these all been covered prior?
Let me know.
