What Is a Deep Cycle Battery?
To understand how a deep cycle battery works, you have to put it side-by-side with a standard car battery. The latter produces a momentary burst of energy to start your car. On the other hand, the deep cycle battery’s design ensures that it provides a steady supply of power for an extended time before it fully discharges.
The discharge value is roughly 80-100%, after which you have to charge it to complete the charging cycle. To better grasp the deep cycle battery’s functioning, you need to know about the battery cycle.
A cycle is the full discharge and recharge of a battery. The depth of discharge is the capacity removed from the battery. The depth of discharge for a fully discharged battery is 100%. The depth of discharge is inversely proportional to the state of charge, which is the remaining battery capacity. So 100% discharge is equal to 0% state of charge.
Back to the deep cycle battery, you find that it handles deep discharges of up to 100%, hence its name. Deep cycle vs. car battery, what is the difference? The main difference is that the former can handle deep discharges without degradation.
For the standard battery, one or two deep cycles won’t hurt. However, if sustained, the cycles may lead to its damage. The deep cycle battery’ resiliency comes from its construction, featuring thicker plates and dense active materials.
On the application of deep cycle batteries, you use them for a motor that requires a steady power supply for a long time. You find it in electric car motors like in electric golf carts, forklifts, wheelchairs, and lifting machines. Recreation vehicles, traffic lights, and renewable energy systems also use this battery.

What Are the Types of Deep Cycle Batteries?
There are two types of deep cycle batteries; flooded and valve-regulated lead acid. Under the former, you have the AGM battery and the gel battery. What is the difference between flooded and valve-regulated lead-acid types?
The flooded varieties have the electrodes fully submerged in an electrolyte. Under this category, we have the tubular and flat plated types. The valve-regulated lead-acid type consists of the electrolyte suspended in a gel-like solution like gel batteries. The AGM batteries have a mat that acts as a sponge to hold the electrolyte in place. Many people prefer the valve-regulated variety due to its sturdiness and longevity.
Deep cycle vs. lithium-ion, which comes on top? In essence, lithium-ion batteries are deep cycles, judging from their charging cycles. Lithium-ion batteries have several advantages over the standard deep cycle.
Li-ion batteries are lighter, have an efficient discharge rate of up to 100%, and have an average lifeline of 2000-4000 cycles, compared to the 400-1500 cycles of lead-acid batteries. Deep cycle batteries come on top at price, as they are relatively affordable.
How Do You Maintain Deep Cycle Batteries?
You have to maintain the deep cycle batteries for lengthy service. Typically, they are not that hard to maintain, particularly the gel and AGM types. You need to have the correct charger and program the voltage setpoints. It allows for proper charging without degrading any parts.
If you have a flooded battery, you need to refill it with distilled water every 2-4 weeks. Check the electrodes and clean them where necessary to prevent corrosion. Do not forget to put the batteries upright to prevent spillage.
Frequently Asked Questions
Q: What Do Deep Cycle Battery Specifications Mean?
When dealing with a deep-cycle battery, you will encounter several specifications that you need to know. Battery capacity, expressed in Amp hour (Ah), shows how much current the battery can deliver. If rated at 80Ah at 20-hours, it can deliver 4-amps for 20-hours. You get this value by dividing 80 by 20.
The other spec that you will encounter is the discharge cycle. It denotes the times the battery can discharge and recharge without deterioration. For instance, 2000 discharge cycles mean you can discharge and recharge the battery 2000 times. Finally, we have the depth of discharge, which is the battery capacity that can be safely released.
Q: Where Are Deep Cycle Batteries Used?
Deep cycle batteries do an excellent job in applications that need sustained and stable current distribution. You find it in electric vehicles, which require adequate power to keep them moving. Electric golf carts, forklifts, and wheelchairs use this battery type. Furthermore, you get them in traffic signals, recreation vehicles, and renewable energy systems.
Q: What Is the Difference Between Deep Cycle and Regular Batteries?
The main difference between deep cycle and regular batteries is that the former can handle deep charging cycles without degrading. Also, it provides a steady power stream over a long time. On the technical side, the difference between a deep cycle and a regular battery is the cold cranking amp (CCA) and reserve capacity (RC).
The CCA is the amps a battery provides in 30-seconds at 32-degrees Fahrenheit. The RC refers to the duration a battery can last while producing 25-amps maintaining at 10.5-volts.
A deep cycle battery delivers half the CCA as the standard lead-acid battery. On the other hand, it has a reserve capacity 2-3 times that of the regular battery.
