What is the Difference Between the Batteries?
The basic compounds of starting batteries and Deep Cycle Batteries are essentially the same--lead and acid. Deep discharge batteries used in recreational vehicles (RV's), boats, golf carts and other electric powered vehicles are designed to provide a continuous current over an extended period of time. These batteries can be routinely discharged to 50-80% depth of charge. To achieve this deep cycle ability, the plates are made thicker. They still have the ability to provide a short but less powerful burst of power compared to a similarly sized car battery.
Starting batteries are designed to turn over an engine and provide high rates of current over a few seconds. These batteries seldom discharge past 20% depth of charge as most vehicles have an alternator that provides the necessary power to run the vehicle once started. To achieve the necessary burst of current these batteries need to have thinner plates which greatly reduces the internal resistance of the battery.
