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.
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.
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 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.
