Deep Cycle
Cycling Systems – Deep Cycle Batteries
A cycling battery should be defined as one that is subjected to frequent or regular discharges and recharges. The discharge may be of relatively short duration but at relatively high current or inversely. The discharge may remove all of the capacity from the battery or only a little, and the recharge may be a full recharge to 100% capacity or a partial charge.
Cyclic use battery could be used on devices that would usually drain out the charge such as water pumps, lights, trolling motors, electric vehicles etc...
