Nut upsuser - Mar 2011 - Cyberpower CP850PFCLCD 120% battery charge

Hello all,

I have a CyberPower Systems CP850PFCLCD that I'm hooking up to NUT 2.4.3
from apt running under Ubuntu 10.04.  Using the usbhid-ups driver, things
*seem* to work at first glance, but there are some odd issues.  The most
notable issue is that the battery.charge indicator reads 120 when at full
charge.  I came across this post here:
http://lists.alioth.debian.org/pipermail/nut-upsuser/2007-September/003222.htmlbut
it looks like the user never supplied the necessary data.

The other issue that I found was that the LB flag is sent way to early when
I unplugged the UPS from the outlet.  I captured a log of upsc polling every
5 seconds and I'm attaching to this message.  I'm more than happy to
supply
debug output, but I don't know if you want me to unplug the UPS from the
outlet during that debug or not.

Thanks in advance for any help,

Justin

Not sure about the 120% charge issue.

The UPS decides when to signal a "low battery" condition, and at this
point in the logs, the UPS's estimation of remaining runtime has  
dropped below the limit. I'd guess that the LB flag is set when either  
the runtime or the charge goes below its limit.

You should[*] be able to use upsrw to adjust "battery.runtime.low",  
but be sure to account for the amount of time needed to sync  
filesystems and kill processes.

[*] Both "battery.runtime.low" and "battery.charge.low" are
flagged as
writable by the driver, but the actual result depends on the UPS  
firmware.

For whatever reason the people that made the UPS firmware decided that  
they didn't need to follow the USB HID PDC specifications. From the  
data you sent, it looks like the value for battery charge that is  
reported by the UPS needs some conversion (coefficient and/or offset)  
to get to the true battery charge. Most likely, this is present in the  
bundled software for the UPS, but sadly we don't know them. So unless  
you're going to change that, the situation is unlikely to improve. It  
looks like '120' means 100% charge, but one data point is not enough  
to find (at least) two missing parameters.

I don't think so. The data you posted indicated that about the time  
the UPS started reporsing LB (low battery), the runtime fell below the  
battery.runtime.low, so this is about right. If you don't need 5  
minutes to shutdown your system, you might try lowering this value (if  
the UPS supports that) and see if this increases the useable time on  
battery.
