I had a power failure today but my syslogs show a battery minimum was hit almost immediately. Then it says the power came back on. Here is an excerpt from today(june 16). The only parameter I have in UPS Settings is Battery % to Initiate Shutdown = 60%.  Why is this happening?  I am not convinced there was a power outage today my stove and microwave clocks still show the time.  UPS reports 100% charge wih ~ 43 Minutes of run time.  I manually powered the server back up ~ 6:30pm and everything seems fine so far.

I could really use some help here.  Same issue again this afternoon, here are the bits from SysLog.txt:

Sounds like the batteries in the UPS are failing.

I am ordering a new set of batteries. I will do a plugs-out test while the array is offline once I get the new batteries and they are fully charged.

or the batteries need to be calibrated

Yeah I was thinking they should plug the battery USB cable into a machine that is running the manufactures software and run a self test on it. See what it says. Usually the self test calibrates the battery like your saying.

Don't actually unplug it, switch off the power to the outlet. Removing the plug breaks the ground circuit, and has the possibility of damaging equipment as any current imbalance travels through network or other still connected cables.

 

You can do a full live test without hurting anything, but it's a little complicated. You need 2 power strips, plug the UPS into one, and the stuff that's normally plugged into the UPS into the other. Approximate the load as accurately as possible, and load up the UPS output to match. Incandescent light bulbs make good small loads, space heaters for stuff above 250ish watts.

 

Run the server up to typical usage, all containers and VM's running as normal, then turn off the power strip running the UPS. The UPS should signal the outage, and hopefully the server will fully shut down before the UPS quits powering the dummy load. Ideally it should be totally done before the batteries reach 50% charge, so as not to stress them.

I powered down the server and installed 3 new 12.7ah batteries into the UPS.

 

Powered up the UPS and ran a self-test/diagnostic.  Powered my server back up.  

 

Brought the server back to normal load with dockers/VM's running.

 

Shut off the breaker to the UPS. Again same issue - Server powers down within a minute of turning off the breaker.

 

If I understand the config it should keep running on batteries until it drops to 60%.

 

What is the issue?

 

 

Try filling in the blank time fields with good values.

Entered legit values for Runtime Left and Time On Battery.  Cut the power at the breaker, this time no immediate shutdown.

 

I let the server run for 10 minutes on battery power then flipped the breaker back on.  

 

I now have a new set of batteries which I probably needed anyways so I think we can consider this resolved.

 

Thanks for everyone's help!
