Traditional starter batteries are designed to deliver just enough current to start an engine. A deep cycle battery is designed quite differently..The plates of this type of product have a denser active mass than the standard plates of car batteries. For this reason they have the ability to withstand the stresses of several discharge cycles without losing active mass or capacity. They are also designed to repeatedly deep discharge before recharging at a constant voltage. For these characteristics they are particularly suitable for golf carts, forklift-type lifters and floor cleaning.
