What is the difference between a deep cycle battery and a regular battery?


If you are like most people, you probably do not give the batteries that power the tools and gadgets you use every day much attention. For instance, you probably have not thought about the differences between the batteries that power your key fob and those that power an all-terrain vehicle. You might not even be able to correctly define what a deep cycle battery is.

All batteries, it is a basic truth, store energy that can be converted into the power required by the gadgets we use. It is crucial to comprehend why some batteries are more expensive than others since the various sorts of batteries you may choose from might function quite differently.

Traditional lead-acid batteries have a lifespan of 200 cycles and are not made for deep discharge, while deep cycle batteries have a lifespan of roughly 2,000 cycles, with each cycle including a complete drain and recharge.

What is a deep cycle battery?

A deep cycle battery is one that is built to provide consistent power production over a long period of time, considerably draining the battery before it needs to be recharged to complete the cycle.

For those who are unfamiliar with them, deep cycle batteries sometimes resemble vehicle batteries. The two battery types are, however, rather dissimilar. Lead batteries, or deep cycle batteries, are created with the intention of giving the things they power long-term energy. These batteries can be recharged, and they typically work well until 80% of the energy they have stored is used up. The extra-thick plates that the deep cycle battery has given it the ability to withstand more discharge cycles than other types of batteries, giving it its moniker.

What is the purpose of a deep cycle battery?

For those who are not familiar, a deep cycle battery is crucial for supplying power for an extended length of time. It is made to survive continuous discharge before being recharged and made suitable for usage once again.

Deep cycle batteries' continuous energy is ideal for applications that prefer a long-term energy source over a battery that can start quickly. If you own a boat, it is likely that you power it with a deep cycle battery. It is regarded by many as the best boat battery. In addition, deep cycle batteries are used for:

  • Golf carts

  • Electric vehicles (such as medical carts or electric bikes)

  • Forklifts (and other vehicles used in material handling)

  • Recreational vehicles

  • Marine applications

  • Renewable energy (made available off-grid)

The most common applications for hybrid batteries are maritime ones. In addition to the typical steady power that deep cycle batteries offer, hybrid batteries also offer the benefit of a starting burst. In most circumstances, deep life batteries made expressly for longevity will outlive hybrid batteries. Let us examine the flooded and deep valve battery types, which are the most often used deep cycle batteries.

Flooded Deep Cycle Battery

A flooded deep cycle battery is the primary variety of deep cycle battery. These are not all that dissimilar from typical lead-acid automobile batteries. The oldest and most widely used form of deep cycle battery is what is today referred to as a "wet cell" battery.

Due to the liquid, they contain, flooded batteries will require more maintenance than other battery types. When the electrolyte levels within a flooded deep cycle battery are low, the owner must replace the battery's liquid container with distilled water.

Pro: Flooded deep cycle batteries are inexpensive to buy and have a design that makes maintenance and repair reasonably easy. The flooded battery type also offers a significant energy boost that may be used for a wide range of applications.

Cons: If care is not taken, electrolytes might seep out of the battery casing if it is not sealed. Additionally, special care must be taken anytime a flooded deep cycle battery is moved in a vehicle due to the tendency for leaking. Low energy density is a trade-off for the battery's strong energy surge. To account for the hydrogen that will be emitted, place your battery in a well-ventilated area during charging.

VRLA (valve regulated lead-acid) battery.

Deep cycle battery

The valve regulated deep cycle battery is the following response to the question "what is a deep cycle battery?" This type of battery, which is also known as a sealed lead-acid battery, does not require watering. Sealed batteries do not need the same care as other types of batteries, but they still need to be checked on a regular basis.

The battery is described as "recombinant," which means that it contains both oxygen and hydrogen. When a battery is recharged using high voltage, the valve that is a feature of this deep cycle battery type is triggered. The battery's capacity is reduced when the valve is opened because materials inside the battery leave. AGM and gel deep cycle batteries are the two available forms of valve-regulated batteries.

How to properly charge a 12v deep cycle battery.

Before learning how to charge a boat battery, people should be aware of the need of making sure the battery is clear of corrosion and dust. Additionally, check sure the battery charger you choose can deliver the amperage your deep cycle battery requires within a reasonable amount of time. Your boat battery will not receive an appropriate charge from a charger that is not right for it, and it might even get damaged.

What should I look for when buying Deep Cycle batteries?

The majority of deep cycle batteries are rated in terms of reserve capacity minutes and/or discharge rates of 100 hours, 20 hours, 10 hours, 8 hours, or 5 hours. 25 amps may be discharged at 100% before the voltage drops to 1.75 volts per cell.

Amp hours is a standard measurement that buyers may use to determine which boat battery is best for them. This rating tells battery users how much amperage they will have access to for a full hour of battery use. The ability of deep cycle batteries to transform chemical energy stored within into electrical energy is measured in amp hours. Users may determine how much battery usage they can get out of a battery by looking at the amp hour rating.

How long will a deep cycle battery last?

They are frequently used in electric vehicles, boats, and golf carts, but they may also be very beneficial in RVs and other off-the-grid living arrangements. What is the lifespan of deep cycle batteries? A deep cycle battery has a 3–6-year average life span.

It is critical to recognize that many manufacturers opt to gauge the battery life of their products using cycles rather than just calendar years. A battery is discharged completely and once during a cycle. The amount of usage you get every cycle depends on how your battery is used, charged, and maintained.

You should keep in mind while doing your calculations that it is never a good idea to let your deep cycle batteries drop to 100% since then you will need to know how to charge a boat battery even more.

Your usage patterns and other aspects unique to your scenario will ultimately define the precise life span you may anticipate. However, by keeping your battery in good condition, you can make sure you get the longest battery life possible. Water should be available as needed, and your battery should never be depleted more than 50%, as advised.

Additionally, you want to choose a charging setup that is suitable for your battery. A deep cycle battery is made to deliver consistent energy over a long length of time.
