charging woes part IV 'The Wrath of Tim'

[tim eh?]

What're the liquid levels like in the internal battery cells? Pop the caps and have a look in each cell to see how much liquid is in there.

The battery should spin the starter from 12.5 like a rocket... I'd start eyeing up the starter.
Try cranking the car over and seeing what voltage the battery drops to while cranking.

I find it interesting from your original post that the battery appears to be losing charge while just sat still outside and out of the car.

at 12.5 it does spin like a rocket... 12.0 not so much I would assume that is normal.
from obc#9 it drops to about 10.5 when cranking.

I am leaving the battery out a bit longer I think will test the voltage drop for a bit. Case is translucent... fluid levels good i think... i tilted it a bit for this photo.
