5500 XR UPS - battery capacity drops from 98% to 38% in 5 seconds

All the batteries were replaced a few months ago (including the 2x ERMs), checked the logs just recently and noticed the capacity drop from   98% to 38% in 5 seconds, during a mains outage.

 

Running power manager 4.3 build 2

 

Goes from 74 min runtime to 27 min runtime in 5 seconds ?  

 

What is going on here?

Does something need to be calibrated?

 

  The power manager software is pretty short on featues compared with APC (will purchasing these in future, rather than HP)

Hi There! 

 

Yes, the latest firmware 2.08 is installed.

 

Using Power manager 4.3 build 2.

 

The  batteries were replaced a few months ago, but there hasn't been a power outage long enough (over 5 seconds) to see the drop in run time until recently. (We are blessed with good power !!)

 

Prior to replacing the battieries, the run time drop was much more significant - 71 minutes down to 19 in only a few seconds.

 if UPS does not provide the expected backup time  - please Be sure that the battery circuit breakers are in the On position.

I had something similar before. In our case the UPS did not understand there are new batteries. There was need of kind of hardware reset. Unfortunatelly I do not remember exact procedure.

Have you read manual at  http://bizsupport.austin.hp.com/bc/docs/support/SupportManual/c00065453/c00065453.pdf ?

For Switching on the UPS battery circuit breaker you can refer to page no 19 of the user guide. (http://bizsupport.austin.hp.com/bc/docs/support/SupportManual/c00065453/c00065453.pdf   )
