Is this battery really 6.5 years old?  Is this part of the problem?  One 
would not expect such a battery to support any load.  I notice that during 
the test, you have little or no load, since despite being in state OB 
DISCHRG the battery.charge is still 100.  It's best to perform such tests 
with a dummy load such as a table lamp and an old fashioned incandescent 
100 watt bulb.

I wonder where the ups.delay.start: 60 comes from.  The NUT default value 
is 30 secs, and you do not change the value in ups.conf.

I'm guessing that this output is in an xterm window or something similar. 
It shows that wall is working but does not show that the wall->Gnome, 
wall->KDE, wall->LXDE, wall->LightDM interfaces are working.  Does a 
Ubuntu user with no xterm window open see the message as part of the 
system notifications?
