I think it should be 'battvolts = x:13.0' from what I've seen from your
previous mails (you'd better check this). This was a reported real voltage,
when the UPS (I guess) was fully charged. You can get the current voltage
 from the upsc output:

battery.voltage: xxxx
....

or from driver debug output:

Asking for UPS status [Q1]...
get_data_krauler: index [03], prefix [(]
Q1 => OK [(234.0 165.0 234.0 000 50.0 13.0 00.0 00001010]
                                       ^^^^

Thanks, I'll correct it!

Btw, please try the complete setup (driver + upsd). What does upsc print?
Also I think you'll have to add the 'ignoreoff' parameter to ups.conf to
make ups.status correct (if it is not).
