Are UPS batteries considered deep cycle?

[Sunking]

No they are not. Batteries for UPS are typically AGM hybrids made with multiple thin plates to achieve extremely low internal resistance so they can provide very high discharge rates in excess of 1C, then be recharged quickly like a car battery. They are made for emergency stand by service. Thin plates = Lower charge/discharge cycle. In other words they only get 100 to 200 cycles in them. You need at least 10 times that for 2 to 3 year battery.
