tell apart starter vs deep cycle lead acid battery

[yuriythebest]

Hi All! I've really tried searching for this but the answers seem to be vague at best as to how to tell them apart - for example boat/RV's batteriesare supposed to be "deep cycle". One video straight up said that if you see the ampere-hour characteristic that means it's deep cycle. Well, what about truck battery's? If there is a lead acid truck battery with SLA 190ah, would that make it "deep cycle"?
