No. > 1. Manuel has the same ups model, and the charge level showed by nut is not > constant. However he seems to be running the initial version from svn. Maybe he read the man page for this driver (or was advised by someone on this list) to setup the 'battvolts' parameter for this UPS. If you didn't configure that, chances are that it will always report 100% charge, since it might fail to determine the battery low and high levels. The UPS doesn't report these and the driver may fail to correctly guess them. See the man page where this is explained. > 2.

The UPS doesn't report the charge level, the Megatec/Q1 protocol doesn't have support for that (yet). It can only report battery voltage at the moment. From that, a charge is estimated. Since this only uses the reported battery voltage, this is notoriously unreliable. > 3.

NUT version? It might also help to upgrade to the latest NUT version and try out the 'blazer_ser' driver. Make sure to read the man page for it, since in some cases it needs some help in setting the right parameters for your UPS. If you feed it the right parameters, it will also do a much better job in guesstimating charge left while running on battery. And looking at the data you provided, it will at least do a better job in determining the number of cells in the battery.
