UPS Battery Disconnect/Reattached errors (APC BX950MI-IEC)

Hello, good people of the Unraid Forums

 

As a new user, might I borrow your collective knowledge and wisdom? 

 

An APC BX950MI-IEC is now connected to my lovely Unraid server "John" via the included USB cable
These recurring messages are filling up the logs:

Nov 27 12:17:37 John apcupsd[18339]: Power is back. UPS running on mains.

Nov 27 12:19:11 John apcupsd[18339]: Battery reattached.

Nov 27 12:24:02 John apcupsd[18339]: Battery disconnected.
Nov 27 12:24:03 John apcupsd[18339]: Battery reattached.

 

 

The messages continue after changing USB ports:

  

Nov 27 12:24:35 John kernel: usb 1-1: USB disconnect, device number 2
Nov 27 12:24:38 John kernel: usb 1-8: new low-speed USB device number 9 using xhci_hcd

Nov 27 12:25:50 John apcupsd[18339]: Power failure.
Nov 27 12:25:50 John apcupsd[18339]: Power is back. UPS running on mains.

Nov 27 12:26:16 John apcupsd[18339]: Battery disconnected.
Nov 27 12:26:17 John apcupsd[18339]: Battery reattached.

 

 

And the same thing happens if I disconnect mains power from the UPS, before a shutdown is initiated:

  

Nov 27 12:40:55 John apcupsd[18339]: Running on UPS batteries.
Nov 27 12:41:03 John apcupsd[18339]: Battery disconnected.

Nov 27 12:42:06 John emhttpd: Stopping services...

 

 

Have we any ideas what the issues might be? I have searched the forums but have not been able to find the same issues mentioned before.

 

Thank you in advance for your insight!!

 

Kindest regards,

    I realise that my reply is long past, but i came across this thread and i am having the exact same issue, with the same UPS.
    Did you come to a solution to the issue?

    Symptoms look like failing batteries in the UPS. Maybe something not properly connected inside the UPS.
