Deep cycle batteries store power in the form of chemical energy. Their design and specs support up to 75% discharge rates without damaging the plates. They are built to withstand repeated discharge and recharge throughout their float service lifespan.
Deep cycle batteries are often used to power systems and electronic equipment that require heavy current bursts during their operation. As such, they can be used to crank your car engine and other related applications. While in use, only a fraction of their total energy capacity is consumed.
There are many types of deep cycle batteries, each suitably designed to power particular electronic systems. Some of the types of deep cycle batteries include Gel, Lithium-ion, flooded and Absorbent Glass Mat (AGM) batteries. The choice of a particular battery depends on durability, battery performance, amperage, among other factors.
This review has rounded up some of the best deep cycle batteries with proven durability and performance. Check them out and also remember to compare their product features so as to get the very best.
