Deep Cycle Battery

Deep-cycle lead-acid batteries generally fall into two distinct categories; flooded (FLA) and valve-regulated lead-acid (VRLA), with the VRLA type further subdivided into two types, Absorbed Glass Mat (AGM) and Gel. The reinforcement of absorbed glass mat separators helps to reduce damage caused by spilling and jolting vibrations.[3] Further, flooded deep-cycle batteries can be divided into subcategories of Tubular-plated Opzs or flat plated. The difference generally affects the cycle life and performance of the cell. The structural difference between deep-cycle batteries and cranking batteries is in the lead battery plates. Deep cycle battery plates have thicker active plates, with higher-density active paste material and thicker separators. Alloys used for the plates in a deep cycle battery may contain more antimony than that of starting batteries.[4] The thicker battery plates resist corrosion through extended charge and discharge cycles.
