Deep Cycle Battery Specifications

Deep-cycle batteries are a type of heavy-duty battery used to power certain vehicles, such as golf carts, and some solar systems. These batteries have the capacity of deep discharge, and longevity is a key feature. They are similar to regular lead-acid batteries but have some factors that set them apart.

Release of Energy

Deep-cycle batteries release energy slowly and consistently. They do not provide sharp bursts of instant energy, and it’s because of this that they are able to last longer than the average lead-acid battery. Deep-cycle batteries are able to generate more power over a prolonged period.


Deep-cycle batteries are designed with thicker plates compared to their ordinary lead-acid counterparts. The plates of a deep-cycle battery are solid instead of sponge-like, as in conventional batteries, and are therefore less subject to warping. The thickness and durability of their plates allows them to withstand deep and repeated discharges.

Discharge Cycles

Deep-cycle batteries are able to go through several discharge cycles, which would ordinarily ruin a regular car battery. These discharge cycles can be deep, utilizing the thicker plates to their full advantage. Although the discharge can be deep, it is advised that they not be discharged below 20 percent of their capacity, because recharging them more than 80 percent can cause damage.
