None other advantage outside of a laboratory.
The myth dies hard.

I respectfully and strenuously disagree.

6V batteries, better known as golf cart batteries, were developed to deal with routine, deep cycle discharging and charging as required by, well a golf cart. But that profile also fits well with RV and boating use.

GC batteries have filler ports on top (many 12V deep cycle batteries do also), thicker plates (don't know about 12V batteries) and more room above and below the plates for electrolyte (AFAIK no 12V battery does this).

No 12V batteries have all of these critical characteristics required for deep cycle use. All GC and GC2 batteries do.

Which is better? The battery that meets all of these critical characteristics or the ones that don't?
