What Is A Lithium Battery? 

A lithium battery is the most expensive battery among other car batteries. Though it is a bit pricy it can store more powers, also rechargeable, which is the big advantage over other batteries.  

This is also known as a lithium-ion battery or Li-ion battery. But a slight difference is there between lithium-ion vs lithium batteries. Lithium batteries have only one cell and are not rechargeable, so only one-time use is available.  

Another hand, lithium-ion or li-ion battery is rechargeable, as the second cell is present in the construction, that’s why they are in great demand nowadays.  

Lithium and graphite are used in this battery with positive and negative electrodes. And thus get the name lithium or lithium-ion battery. This kind of battery can work efficiently with electric vehicles, and also as a second battery for car audio. 

How Does a Lithium Car Battery Work?

Before knowing about the lithium battery, many people mind one question may arise how these batteries work. Although this is not mandatory to know.  

A lithium car battery looks like a box containing small battery cells in it. Each cell has three important components. The positive electrode, a negative electrode, and an electrolyte layer.  

The positive electrode also known as cathode made with lithium, negative electrode stands for anode made with graphite. When discharging the lithium ions go from cathode to anode and the opposite thing is happen when charging.  

These ions work as energy. This kind of construction provides a longer life battery life.

In one word, having the Best Lithium Battery For Car Audio especially from our list can help you explore your audio worlds more excitedly.

Lithium Battery For Car Audio VS Other Battery: Which Is Better?  

Besides lithium, there are different kinds of car audio batteries are present. For a deeper knowledge about lithium battery, if it is good or not from others, also the difference with other batteries, this section is gonna help you.

Lithium Battery VS AGM Battery

The first difference between lithium and AGM batteries is the cost. AGM batteries are much affordable than any lithium battery. Also, AGM batteries are widely used in everyday life vehicles.  

The next, thing is the DOD sensitivity. AGM batteries are sensitive to DOD rate. DOD stands for depth of discharge. This indicates the battery lifespan also.  

The more the batteries are discharging the fewer cycles would become. But this doesn’t suit a lithium battery. They have a DOD rate of 80% or 90% sometimes. That’s why a longer lifecycle with the expected capacity you can have.  

The weight is also heavier than AGM or lead-acid batteries. But lithium batteries you can find much lighter.  

Though lithium batteries are ruling over people’s cars AGM batteries are serving for approximately 150 years. They can charge in any weather or temperature condition, in contrast, lithium batteries can not do that.

AGM Battery

Weize 12V 100AH Deep Cycle AGM SLA VRLA Battery, in Series 24V 36V 48V  

Lithium Battery VS Calcium-Calcium Battery 

In a calcium-calcium battery, calcium plates are used. They get charged separately and also minimize the discharging rate by reducing fluid usage. This works as the best alternative to a lithium battery.   

Unlike AGM battery this battery has many advantages like a lithium battery. So, if anyone intends to have a calcium-calcium battery for car audio, this will ensure a great performance overall.  

Lithium Battery VS Wet Cell Battery  

Unlike lithium batteries, wet cell batteries use electrolytes or mostly known as sulfuric acid. There is a minimum of 6 cells contain this battery. This battery is also spill-proof meaning it prevents fluid spilling.  

This battery is also considered as the lowest maintenance, absolutely perfect for lazy music lovers. This is also a huge benefit of lithium batteries. So, if anyone is too lazy to maintain batteries this kind of battery can work best for them.   

Some Safety Concerns About Lithium Batteries 

We can not deny that lithium batteries have a great benefit and are much better than other batteries. But still, some safety concern always remains when it is about lithium or li-ion battery.   

As it is temperature sensitive, this battery needs to stay at room temperature. If the temperature is high then there is a chance of catching fire or explosion. Or, in low temperature, the battery is also affected and thus causes several damages.  

Besides temperature, one of the biggest concerns is overcharging. Overcharging must cause a dangerous explosion or fire. When the battery gets overcharged by electrolyte decomposition some gas production within the battery.  

Because of these concerns lithium batteries need to be maintained properly.  

But today’s latest chemistry batteries have come lithium-iron-phosphate which eradicates all kinds of overcharging, overheating problems. So, the safety is no longer valid now. 

How To Choose a Suitable Battery For My Car Audio System? Buying Guide  

Before buying a battery for car audio whether it is lithium or other some criteria everyone should consider. These points will help you to buy the right one for your car.  

Cranking Amps/ Cold-Cranking Amps   

Cranking Amps or CA is referred to the car battery output power or current. The RMS wattage of the system and the CA rate have to be the same or sometimes a higher CA rate can work. But not less than the RMS power.  

Another hand, CCA or cold-cranking Amps is the same concept as CA. The difference is only in the temperature. CA is measured at 0 degrees Celsius and CCA is measured at –18 degrees Celsius.  

In CCA like the CA, wattage power needs to be compatible. So, before buying a battery look at this factor at first.  

Battery life  

Another important fact is the battery life. Check out the car audio battery what time it takes to charge or discharge. Also, if your battery has already been manufactured for about 6 months or above try to avoid that. Because if batteries remain without charge for a while, it causes some internal damages. 

Battery Size  

Before buying a battery must see the size if it matches your car space or not. The battery size should not be too big that will be a total wastage of money. Moreover, a loose battery sometimes creates vibrations. So, size and fitting matter.  

Final Verdict  

Today people are more concerned about having the best product for their audio system. It can be for home or car everyone wants the best one. Thus, upgrading and getting the full entertainment we present a list of the Best Lithium Battery For Car Audio 

No battery now can compete with a lithium battery for efficient performance, low maintenance. Though these batteries are expensive but with other batteries you need to replace them after a short time.  

But lithium batteries can ensure a long life span. So, without further concern choose one of the batteries from our list, and enjoy the ultimate entertainment in your car.
