You are on target. deep cycle have thick plates with less surface area. start batteries have thinner plates with much more surface area.I believe that AGM batteries, as well as the conventional lead acid batteries used as ‘House batteries’ are fundamentally different from chassis batteries. The house batteries are deep discharge batteries, designed to provide current over a long period of time. The chassis batteries that cars and RVs use are designed to put out the massive amounts of current— but only for a short time—needed to start an engine.
