Check out this thread and do a search...lots of info from people that know more than me and I worked in the battery industry for 6 years designing automation equipment.

Most "dry" cell batteries use Absorbent Glass Mat (AGM) separator material between positive and negative lead plates to isolate them from on another. The AGM separator material absorbs the hydro-sulphuric acid like a sponge so that there is no "free" acid in the battery like in a standard flooded-cell type automotive application. Standard modern flooded-cell technology uses a polyethylene/silica separator material to isolate the plates, where either the positive or negative plates are enveloped or encapsulated by the thin (~.006") PE material.

The only difference between the two battery types you're describing is the shape of the lead plates. A more typicaly AGM battery design uses flat, rectangular plates to make the groups whereas the Optima/Orbital type design uses much wider plates wound in a spiral cell.

That's a very brief description, hope it helps.
