power consumption after shutdown

[Mikus Grinbergs]

My apologies for not being clear.  I'll try again:

I want to feel that the battery that I just put into the XO I'm 
walking out the door with is as "charged up" as it normally can be.

1)  If that battery came from an XO that was plugged into the AC
     24/7 for the past week -- I *think* it is fully "charged up".

2)  If that battery came from an XO that had been "shut down" for 48
     hours; but then that XO had been plugged into the AC until the
     'power' light went green -- I *think* it is well "charged up".

3)  If that battery had been sitting on the shelf (not in an XO) for
     a month -- what did I need to do to make it "topped off" ?

Sorry - I did not mean that I cared exactly how "charged up" it was 
-- what I want to know is how to ensure to myself, without going to 
extremes, that the battery was "well charged up".   [Is 94% reported 
by the pop-up for an on-the-shelf battery believable, or is the 
'true' value half that?  And if do I see 94%, do I need to worry 
that "this is a battery that requires some more charging"?]

I was under the impression that when the battery charge went 
somewhere below about 97%, the XO would "charge it some more".
So I was surprised to have it stay at 94%.   [If 94% being shown on 
the pop-up is not low enough for "charging some more", then how can 
I initiate charging being performed by the XO ?]

Apologies for being unclear.  I'm not particularly interested in the 
precision of the "state of charge".  What I am interested in is "is 
the battery as 'well charged up' as I can make it be by using the 
XO's 'built-in' charger - I will want to get the most minutes of use 
of my XO when carried to a place that does not have electricity" ?

And if it is not 'well charged up', what do I need to do to make it 
  so?   In particular -- if it *were* 90% "charged up" when I took 
it off the shelf, would I have to fully discharge it in order to 
then "charge it up" (using the XO as the 'charger') closer to 97-99% ?
