I bought an APC UPS from a local seller. Seller claimed that UPS is 2 years old but when I checked the timestamp on the UPS, it says 8 years old. Initially, all signals from the UPS looks good on the steady state, it even says it passed the self-test. It gives several hours of runtime for battery as an estimate and no errors for bad battery.
Unfortunately, UPS simply does not power up the devices when power is cut. I have tried many configuration and settings but my guess is that it is bad battery because battery lasts only 15 minutes under 80 watt load but I am not sure because seller claims that he tested the unit and it worked perfectly fine and the problem is that I don't use the powerchute software. I think he is telling the truth and he also offered me to fully refund the money and I have no prior experience with UPS's so I wanted to double check with experts here. I have spent several hours yesterday to read and learn about UPS behavior and everything indicates bad battery.
I actually made a small video to show how UPS behaves when power is cut. It seems like UPS simply goes black and come back in a state where power is cut from devices:
The movie is taken when UPS is under 70-80 watt load from LED lights. As you can see, when I unplug the UPS light goes off, UPS gets into shutdown mode. I can manually turn on the battery power after cancelling the shutdown. It would be to good to hear from experts if this is simply a bad battery issue.
Seller offered to take it back but I need an UPS so I am happy to keep it if problems will go away after battery is replaced.
