What Is A Deep Cycle Battery

This deep cycle stickered Kirkland battery lasted less than 35 real-world deep cycles.

What is a deep cycle battery. They are designed to be discharged down to 20 of their maximum charge repetitively. The nomenclature of deep cycle batteries comes from the fact that they are designed to be discharged as fully as possible each time they are used a deep-cycle of the battery. If you have a solar panel system a recreational vehicle or any deep cycle battery application need you must have it.

The normal battery is designed in such a way that when it is completely discharged it causes an increase in the amount of sulfate on the plates. The acid is contained within this glass mat making the battery unspillable even when tipped on its side. A deep cycle battery is a lead battery designed to provide sustained power over a long period and run reliably until it is 80 discharged or more at which point it needs to be recharged.

To accomplish this a deep cycle battery uses thicker plates. Deep Cycle Batteries. A deep cycle battery is also designed to be deeply discharged and charged over and over again without shortening the lifespan of the battery.

It is important to note that although deep cycle batteries can be discharged up to 80 most manufacturers recommend not discharging below 45 to extend the life of the battery.

Ask yourself is this CostcoKirklandJohnson Controls battery really a deep cycle battery just because the sticker says so.

A deep cycle battery discharges within 45 to 75 of its capacity. A deep cycle battery is also designed to be deeply discharged over and over again something that would ruin a car battery very quickly. These thicker plates have less surface area and thus less of the instant power that a starting battery needs.
