Hi, this article may help: [URL]   The controller needs to run the learn cycle at least once to determine the actual capacity of the battery with accuracy. This first learn cycle will be scheduled to run 90 days after initial boot up, or after identifying a new battery. Even if the learn cycle is in warn mode the first learn cycle will run.After the first learn cycle has been executed and the mode is set to Warn:when the learn cycle is due, the controller Firmware issues a warning and the battery will be set to degraded state   And from a previous post: [URL] “Every 90 days, the PERC's initiate a "learning cycle", which completely drains the battery, then recharges it. During this time, write cache is turned off, an warning and error thresholds are tripped for the battery charge.”   The logs will be looking like this for example: 02/27/20 15:34:28: C0:Next Learn will start on 05 27 202002/27/20 15:34:28: C0: *** BATTERY FEATURE PROPERTIES ***02/27/20 15:34:28: C0: _________________________________________________02/27/20 15:34:28: C0: Auto Learn Period : 90 days02/27/20 15:34:28: C0: Next Learn Time : 64390886802/27/20 15:34:28: C0: Delayed Learn Interval : 0 hours from scheduled time02/27/20 15:34:28: C0: Next Learn scheduled on: 05 27   And when the cycle starts: 05/27/20 15:36:58: C0:EVT#01296-05/27/20 15:36:58: 151=Battery relearn started05/27/20 15:38:03: C0:EVT#01297-05/27/20 15:38:03: 152=Battery relearn in progress05/27/20 17:13:23: C0:EVT#01298-05/27/20 17:13:23: 148=Battery is discharging05/27/20 20:28:23: C0:EVT#01299-05/27/20 20:28:23: 153=Battery relearn completed05/27/20 20:28:23: C0:Learn completed successfully.   Hope this helps. Happy New Year!
I've been recently asked to do server-side work at our IT company and am brand new to OMSA. After a few hours of Googling, I finally got OMSA installed (though it may have already been installed...It just didn't show up in the start menu when I searched "Dell"..) and exported the PERC logs using this KB. According to this thread and this site, you need to check if your battery's Absolute Capacity is <33% to determine it's unhealthy and needs to be replaced. However, my logs don't show the "Absolute State of Charge":     I tried ctrl+F for absolute"  with no results. How can I grab the absolute charge? Is it sitting right in front of me? P.S. In the excerpt above, I clipped the bottom of the log file, which has a timestamp on each line. What's the significance of the logs at the top of the exported log file without timestamps? (excerpt below)      
PERC logs don't show "Absolute State of Charge" (Only Relative)
