Deep cycle batteries are one type of rechargeable battery while starting batteries are another. These batteries also store energy like a starting battery.
But are you confused with the difference between other batteries and deep cycle batteries? Let me clear your confusion by giving the complete detailing guide.
So, in short, The difference is that it uses that energy to maintain a steady discharge level.
They are typically employed in applications that involve more substantial energy usage compared to starting batteries, which are employed for small energy demands, such as the starting of an engine.
Consider the below full guide so that you will get complete information about deep cycle batteries.
WHAT DOES “DEEP CYCLE” IMPLY?
A deep cycle refers to the ability of a battery to store and deliver a large amount of energy and remain functional and not be damaged by doing so.
It is usually used in the context of batteries used in vehicles and boats. These batteries are meant to hold a lot of energy and be discharged and recharged on a regular basis.
This is opposed to starting batteries that are used to provide power for a short time such as starting a car.
In RVs or boats, deep cycle batteries are used in situations where they will be used continuously for a long time.
A deep cycle battery is different from a more commonly used battery such as a car battery, it contains far more lead and more plates.
Two Different Types of Batteries:
As you all know, there are lots of different types of batteries available in the store. All the batteries have different features and sizes and amps.
Here is a quick overview of starter batteries and deep cycle batteries.
Starter Batteries Vs Deep Cycle Batteries
There are 2 main types of batteries – deep cycle batteries and starter batteries. The difference between the two is crucial to understand for anyone who owns a vehicle.
The starter battery (also called SLI battery for ‘starter-lighting-ignition’) is the one that starts the car. It needs to provide a burst of power to turn over the engine.
While the deep cycle battery provides the power to run all the accessories in the vehicle. It is usually bigger than the starter battery but lacks the ability to turn the engine over.
It is designed to provide power over long periods, making it ideal for use in cars, RVs, boats, and other vehicles that need to run electrical devices over an extended period without recharging.
If you are thinking of installing a solar system to power your vehicle’s electrical devices, you will need to get the right battery to match the system.
WHEN SHOULD A DEEP CYCLE BATTERY BE USED?
Deep cycle batteries deliver long-term energy, making them appropriate for uses that don’t require a quick start.
The following are some of the most typical applications for rechargeable batteries:
- Applications in the marine environment
- Vehicles used for recreation
- Material handling, which includes the use of forklifts
- Off-grid renewable energy golf carts
Hybrid batteries are another option for some applications, particularly maritime applications.
A hybrid Marine Battery can provide a beginning burst and continuous power for maritime applications, although it has a shorter life expectancy than a dedicated duty battery.
TYPES OF DEEP CYCLE BATTERIES:
Functionally, there are two common types of deep cycle batteries that you may look at in their features. One is the flooded deep cycle battery, and the other is the sealed or maintenance-free deep cycle battery.
1. Flooded Deep Cycle Battery:
Flooded deep cycle batteries, also known as “wet cell batteries,” are designed for frequent but shallow discharges.
They can be cycled hundreds of times and provide the longest service life of all lead-acid battery types.
In contrast to golf cart batteries, they can be discharged down to 20% of capacity. Because flooded lead-acid batteries are designed to be discharged to a greater degree, their self-discharge rate is also greater than AGM or GEL.
Wet cell batteries are also known as “flooded” or “spillable” because the internal liquid can escape through the vent caps.
That is why they are always installed in a “V” or right angle position so that any leaked liquid can run out.
2. Maintenance-Free Deep Cycle Battery:
The second type of deep cycle battery is the maintenance-free deep cycle. When you need to change the battery, the cost of replacing your battery can be prohibitive.
If you have to repair it, the cost can be even higher. Therefore, you need a maintenance-free deep cycle battery.
A maintenance-free battery is sealed, so you don’t have to add water to it. If you want to take a deep breath and know your battery will last for years to come, you need a maintenance-free deep cycle battery.
How To Maintain A Deep Cycle Battery?
Whenever you need to maintain a deep cycle battery, you should keep an eye on your maintenance to work well.
Here are a few ideas to keep your deep cycle battery in good working order:
- Firstly, you have to charge the monitor to Start charging at 50% and don’t let it fall below 20%.
- Even if you’re not using it, keep it charged to avoid sulfation and extend battery life. If you’re not going to use your flooded, gel, or AGM batteries for a long time, trickle recharges them (lithium batteries don’t need this).
- Allow the battery to cool down after prolonged operation to prevent grid corrosion.
- Clean the battery terminals and covers to keep them free of dust and corrosion.
Deep cycle batteries are used in solar and wind power storage systems and RV and boat electrical systems.
These applications often require a battery with a high capacity and a high discharge rate, and these features are what set deep cycle batteries apart from starting and automotive batteries.
Through this article, I hope your confusion regarding what is a deep cycle battery will be clearer.
