Parallel 12volt, more capacity then AH rating? 2.7 x's more!

Just to throw another wrench in the works. Per my other posts on 12v vs 6 volt I found some vids that seem interesting It seems this guy tested parallel 12 volters. Nothing about voltage drop ...

I vote for believing the published specifications, since expensive lawyers have to sometimes back them up.

I see nothing wrong with CCA and MCA values being published for a true deep cycle battery. These parameter values might merely read a little lower than those for a starting type battery. Not a big deal if one can live with the lower CCA and MCA values while at the same time getting true deep cycle performance when that is needed.
