But before that let’s look at the basics of AGM batteries and lithium batteries:
Table of Content:
What are AGM Batteries?
AGM is an abbreviation for Absorbent Glass Mat. Technically, AGM batteries are lead-acid batteries, but they are a more improved version of them. Whilst flooded lead-acid batteries are still widely used, they offer a significant improvement.
This type of lead-acid battery is easier to use. They charge more quickly than their elder siblings and emit little to no off-gassing. Another significant advantage is that they do not require the same level of maintenance as standard lead-acid batteries.
Technically, AGM batteries are sealed. As a result, you may avoid the inconvenient “watering” of your batteries. They are designed to generate intense bursts of starting amps and to keep devices running for longer periods.
AGM batteries feature a sealed design and straightforward construction. They are made up of a positive plate, a negative plate, and a fiberglass separator that sits between the two plates.
The separator is in charge of containing the electrolyte, which is a solution of sulfuric acid and water. As the battery is charged, the acid and water combine to form electrons, which travel between the plates to provide an electrical current.
Advantages:
Here are some of the main advantages of AGM batteries:
They Are Not Prone to Spills:
AGM batteries, unlike regular lead-acid batteries, feature glass mats that prevent this from happening. Furthermore, the purpose of these glass mats is to prevent spillage. Rather than consuming the electrolyte, the glass mats keep it in place, preventing it from flowing over, even when the battery is in an unusual position.
They Have a High Output Power:
AGM batteries have low internal resistance due to the way they are built. As a result, they may produce adequate bursts of power when needed, such as when starting a battery. Because of this characteristic, these batteries respond to loading better than any other battery on the market.
They are Durable:
These AGM batteries were initially intended for use in the aerospace sector. This implies they have a strong design that can withstand extreme vibrations, such as those seen in military and commercial airplanes.
They are popular among high-end motorbike riders and race car drivers because of this feature. Its sandwich construction style assures that its interior components do not come apart.
Furthermore, they are impervious to the ensuing wear and tear caused by frequent vibrations. They can also resist major temperature changes.
Disadvantages:
Despite their numerous advantages, AGM batteries have certain disadvantages. Among these are:
They are Vulnerable to Overcharging:
As compared to flooded batteries, these AGM batteries have a limited tolerance for overcharging and high voltages. They have a shorter life expectancy if they are subjected to these situations.
Energy Problems:
These AGM batteries offer a high-power output but low specific energy. A high specific load is often necessary for batteries that must run for an extended period under a moderate load. As a result, these batteries are unable to power multiple devices.
What are Lithium Batteries?
A lithium battery like the Super B Nomia 12V210AH is a high-tech battery that uses lithium ions as a significant component of its electrochemistry.
Metallic lithium is used as an anode material in lithium batteries. They are distinct from conventional batteries due to their high cost per unit and great energy density.
Lithium-ion batteries have been increasingly popular over the years, and this is because of the reason that they are one of the most powerful and dependable rechargeable batteries available.
They are utilized in electronic devices like mobile phones and laptop computers, as well as by automobile firms for electric cars.
All lithium batteries function in much the same way. While the battery is charged, the lithium-cobalt oxide positive electrode releases part of its lithium ions, which flow through into the electrolyte to the negative, graphite electrode and stay there.
At this time, the battery absorbs and stores energy. When the battery discharges, the lithium ions migrate back across the electrolyte to the positive electrode, generating the energy that powers the battery. In both circumstances, electrons travel in the opposite direction to the ions from around the outer circuit.
Advantages:
There are many advantages of lithium batteries, but some of them are as under:
Easy to Maintain:
When opposed to nickel-based batteries, lithium batteries like the Super-B Epsilon 12V90AH are simple to use and need less maintenance. There is no need for priming equipment, and they do not require planned cycling to preserve their battery life.
Lithium batteries also do not have a memory effect, which would lead batteries to run at a decreased capacity after several partial discharge and charge cycles.
There Is No Need for Priming:
Upon receiving their first charge, certain rechargeable cells must be primed. One advantage of lithium batteries is that they are delivered fully operational and ready to use.
Lightweight:
Since lithium batteries are lighter than other types of batteries, they are a good choice for portable gadgets and electric vehicles.
Disadvantages:
Despite their numerous advantages, Lithium batteries have certain disadvantages. These include:
Requires Battery Management System:
Lithium cells and batteries are less durable than other rechargeable technologies. They require safeguards against being overcharged and discharged too far. In addition, the current must be kept below safe limits at all times.
As a result, one downside of lithium batteries is that they require protective circuitry to guarantee they remain within their acceptable working limits.
Technology Advancement:
Even though lithium batteries have been around for a while, some people may still view the technology as being in its infancy because it is still very much in the development stage.
This has the potential to be a drawback because technology is always evolving. Yet, the constant development of new lithium technologies may also be a benefit since it leads to the development of better solutions.
AGM Battery Vs Lithium Battery:
Here are some of the main differences between AGM batteries and Lithium batteries that set them apart from each other:
AGM Vs Lithium Battery Lifespan:
When it comes to longevity, lithium batteries are typically thought to outperform AGM batteries. Lithium batteries normally have a lifespan of 5 to 7 years, whereas AGM batteries have a lifespan of 3 to 5 years, depending on usage and care.
Lithium batteries have a longer lifespan due to their chemistry and manufacturing. Sulfation and stratification, which can limit the capacity and longevity of AGM batteries, do not occur with lithium batteries.
Moreover, lithium batteries can be cycled several times than AGM batteries without losing capacity, which can considerably increase their lifespan.
Performance:
What is the point of getting a new battery if it is not going to last? Fortunately, both AGM and lithium batteries outperform flooded lead-acid batteries.
But who will emerge victorious in the battle of the batteries? Here is a short rundown of performance at different temps.
Lithium batteries are outfitted with a battery management system. Lithium batteries are protected from over or under-protection, as well as from harmful temperatures. If the temperature is too high or too low, the BMS will protect your batteries.
As a result, lithium batteries will not receive a charge when the temperature is below freezing. Since AGM batteries lack a battery management mechanism, they may take charge. It’s also conceivable that this will harm the battery.
When it comes to running at hot and low temperatures, both types of batteries perform similarly. You should look at the temperature range for the battery you are interested in, however, lithium and AGM perform similarly.
If you need to charge a battery in cold weather, a Super B Andrena 12V15AH-SC lithium battery may be the solution. This choice is suitable for RVers who travel in tough conditions.
Environmentally Friendly:
Lithium batteries are thought to be safer than AGM batteries. Nonetheless, AGM batteries are a significant improvement over the flooded lead-acid battery.
Because AGM batteries are sealed, there is minimal to no off-gassing. But, unless you are seeking a more ecologically friendly and safe choice, a lithium battery like the NOMADA 12V105AH takes the lead. Lithium batteries are non-toxic and do not leak. Both types of batteries may be recycled.
AGM Battery Vs Lithium Battery Price:
In terms of cost, AGM batteries are often less expensive than Lithium batteries. AGM batteries are widely accessible and utilized in a broad range of applications, including autos, boats, and backup power systems. They are also mass-produced, which contributes to their inexpensive cost.
Lithium batteries, on the other hand, are more expensive than AGM batteries due to improved technology and greater production costs. Lithium battery materials are much more expensive to produce than lead-acid cells used in AGM batteries.
While lithium batteries are now more expensive up front, they can save you money, in the long run, owing to their longer lifespan, improved efficiency, and fewer maintenance requirements.
It is important to assess your application and requirements while deciding between AGM and Lithium batteries. AGM batteries may be the preferable alternative if cost is a consideration and strong power output is necessary.
Lithium batteries may be the preferable choice if size and weight are important, and you need a higher energy density and charge efficiency.
