Thanks mates,
as suggested I have added

    runtimecal = 240,100,720,50
    default.battery.voltage.low = 10.4
    default.battery.voltage.high = 13.8 (the actual charging voltage)

In ups.conf

I have also added the startup procedure in rc.local file, everything is
I have only to make a deep test.

Is there a way to add a NOTIFYMSG value for the battery test?

Thank you lots
