Got this UPS on eBay as a “working unit” long story short it was a scam.

Now the UPS passes power to the normal AC power strip it has. However the battery + AC power outlets don’t pass voltage.

I also tested the LCD desplay and its getting a VERY low voltage

Now I am thinking this has something to do with it having no batteries, but that shouldn’t be the case, how would it charge if they were to run out of power? Has anybody here had this issue with there UPS?

    I had an idea it’s configurable in its admin-panel, but it may not. Please check the following:

    So, to conclude: the official documentation is right. Hot-swappable or not, the UPS cannot boot without at least a bit of charge in the batteries. That’s all it requires to come back online — and start to fully charge the batteries. I did not experiment to see if, after having booted, I could remove the batteries at will and put them back in again, with the UPS automatically managing the switch to AC power. So that question remains unanswered.

    The problem, in your case (as well as on mine) is that the batteries have to be installed first before you know if the motherboard is fine or not.

      Maybe I could hook my bench power supply up to the wires to test it? Although it only goes up to 14.4 volts so if it takes 24vdc I have no way of testing. I could go to the local electronics store and ask for old batteries and get them on the cheap just to test.
