"Dual purpose" battery might be common on small TT, though there isn't much reason to choose it over a deep cycle in this application.
The terminology can be a gray area, because - Marketing.
Dual purpose (often called "Marine" or "RV" batteries) are very readily available. Many batteries labeled as "Deep Cycle" fall into that category. If you look at a Walmart "Deep Cycle" battery, it's hyped as "maintenance free," meaning it's not built so you can check and fill the cells with water - something a real deep cycle battery would always allow. But, they sell lots of 'em to RVers, because they're inexpensive, readily available, "deep cycle" batteries.
A true deep cycle battery, such as made by Trojan, Rolls-Surrette, or Concorde, is much harder to find and much more expensive.
