The Optima showed 12.6 volts when I got it, and after jumping it with the Trailblazer to see if the extra voltage would help, it shows just over 13 volts now. It's disconnected until I return. I'm off work longer than I will be gone, so maybe I can get it figured out before I have to go back to work.
Check for corrosion in the neg. cable, cheap to replace.
