APC 800i, no lights, no power, nothing...

[BillP]

Hi! Recently I got an used APC 800i unit, the problem, is that does nothing, no power, no lights, no errors, no beeps... simply nothing.

Any ideas? Also, reconnected all the batteries, but nothing happens, I want at least an explosion hehe.

Antoher thing, it's necessary to connect something to the UPS get it charging or showing up something?

How old is the battery in the UPS? Can you measure the voltage on the battery by chance?

What is the background on this unit - is it older? Was it in storage?
