So I have a used Tripp-Lite SMART1500RM2U that I put in my rack for my homelab. I replaced the batteries some time in 2022 and they were rated for this system. They all tested fine, the UPS reports no issues with them. However I’m experiencing some issues with the UPS.

​

  1. The UPS on power outage will drop power to devices plugged into it.
  2. The UPS does not power back on when power is restored.

I’m working on troubleshooting some more like unplugging the unit, but since it’s in a live environment, I need to plan the environment to be down for testing.

Any suggestions on things to look into?

    The UPS on power outage will drop power to devices plugged into it.

    Have you ran a Test button to see if the UPS works / battery works and actually provides power? A component may have failed inside the UPS, the battery may be bad, or the wire connection may be poor. Did everything work, tested with no power, with the previous batteries?

    The UPS does not power back on when power is restored.

    That’s normally a setting that’s configured. Staying off is safer, in case the battery didn’t get enough time to charge back up and power immediately goes out again.
