I have been following this post and have learned a lot. I had no idea there was a proper way to connect two batterys in parallel before being educated by the various posts.
One thing that has not been discussed is the internal resistance of the battery. I was always taught that compared to dry cells a lead acid battery has a very low internal resistance which is in part, why it can deliver the high amperage required for starting. The internal resistance of the battery is not typically listed in the battery specifications. However, I did find it listed in my Optima battery brochure, or you can check; (www.optimabatteries.com).
They list a 12V at 800 CCA, internal resistance of .003 ohms, weight of 37.9 Lbs and a 6V at 800 CCA, internal resistance of .0019 ohms, weight of 18.5 Lbs.
I believe the two 12s in parallel would translate to, two resistors in parallel for a total resistance of .0015 ohms. The two 6s in series would translate to, two resistors in series for a tatal resistance of .0038 ohms. This would seem to be a significant advantage for the parallel connection.
Not claiming to be a sparkie perhaps someone else can comment.

Today's Featured Article - Identifying Tractor Smells - by Curtis Von Fange. We are continuing our series on learning to talk the language of our tractor. Since we can’t actually talk to our tractors, though some of the older sect of farmers might disagree, we use our five physical senses to observe and construe what our iron age friends are trying to tell us. We have already talked about some of the colors the unit might leave as clues to its well-being. Now we are going to use our noses to diagnose particular smells. ELECTRICAL SMELLS
