Regular car batteries are designed to provide a brief but violent burst of power to start the vehicle's engine. However, sealed deep-cycle batteries have thicker plates and denser active materials to withstand repeated charge and discharge cycles.
Sealed deep cycle batteries are available in two capacity ranges: 6 volts and 12 volts. A flooded lead-acid battery is a type of deep-cycle battery, sometimes called a lead-acid, FLA, or wet battery, that consists of a lead plate or grid with a liquid electrolyte, usually concentrated sulfuric acid, in a container.
As the cheapest and oldest battery technology, it has been popular with practitioners of budget-conscious and off-grid living. Considering the ratio of the battery's weight to the energy it provides, the FLA is quite heavy. As a result, the popularity of this type of battery is waning.
