As a High Cycle this battery is built to allow for a high number os cycles (discharge - recharge) and therefore has an extended life span. However High Cycle batteries are not suitable for deep cycling and are generally built to discharge to depths of 20%. If you anticipate using more than 20% of your batterys capacity on a regular basis, then you must opt for the Deep Cycle. Using a High Cycle in a cyclic application would lead to premature aging and subsequent replacement of the battery.
