Actually about 11.88 is 100% discharged so you need to redo your math.
Like I said before, a voltage reading of 11.96 indicates an 80% discharged
battery.

Sorry, I don't follow you. Please 'splain me it.
I'm pretty sure my cars start easily with 11.88 vDC. It's not even close to
being fully discharged.

A battery is not like a capacitor. While the voltage and charge still are
related, it is not a linear relation. First hit on google actually seems
to agree with Mike. http://www.wind-sun.com/PDF_Files/battvoltandsoc.pdf

If your battery is putting out 11.88 V while you are cranking, sure. If
that's your battery's voltage at rest and it still has that much charge, I
imagine you must have a very large battery.
