Deep Cycle

Unlike starter batteries, which are made to provide a strong burst of power for a brief amount of time, deep cycle batteries are rechargeable batteries designed to be frequently deeply depleted and recharged. Deep cycle batteries are frequently used in systems that need for continuous power over a longer length of time, including backup power systems, marine and RV applications, and more.

Compared to beginning batteries, deep cycle batteries have larger plates and a different chemistry, which enables them to discharge a sizeable percentage of their stored energy without degrading their performance or lifespan. Lead-acid batteries (flooded, AGM, or gel) and lithium-ion batteries are the two most popular forms of deep cycle batteries.
