Battery for Car Audio – Buying Guide:

We have talked about some of the best batteries available in the market these days, but that is not all. Before you chose a particular product for your car, there are other things you need to address.

Having a quality sound system in your car is fun, but it puts a lot of strain on your car battery. That’s why it is recommended that you acquire a quality car audio battery. This extra battery will be solely dedicated to power on your sound system. So, your sound system will perform exceptionally well without affecting your car’s performance.

Before you rush to pick the best car audio battery for your powerful stereo system, you need to consider several things. Check out the available space that you’ve for installing the battery, know the wattage of the whole sound system, the number of cold-cranking amps, and its reserve capacity.

In the following section, we will talk about all the things you need to put on your checklist before going out to shop for a car audio battery. Then, we will address some of the frequently asked questions most buyers have.

The Need for A Separate Battery For Your Car Audio System:

We need to discuss in detail why you need to get a separate battery just to operate your audio system.

When you fit a stereo system in your car, especially a large one, it will need a higher output power to work; thus, it drains large amounts of current from your car’s battery. This can put a strain on the battery that is already powering various components of your car.

This is where the need for an extra battery comes in. The audio system can be connected to the second battery that’s sole purpose is to provide your system without lagging the performance of any other component. Another reason to invest in a second battery is to use the stereo system even when you turn off the engine.

Factors to Consider before buying a Car Audio Battery:

Cold Cranking Amperage:

Cold Cranking Amperage or CCA is the charge capacity of your battery. Most repair shops can estimate the charge capacity your battery possesses.

A battery that you are buying should have an amperage that matches the number of watts that it produces. Higher amperage of CCA will produce a higher amount of power.

Reserve Capacity of a Battery:

The reserve Capacity of a Battery lets you know the time it will run without the need to charge again. Usually, people prefer a battery with a couple of hours of reserve capacity, especially if you plan on using your car’s audio system when the engine is off.

Moreover, suppose you are thinking of running a few other accessories on the battery. In that case, you should look for a Battery with a higher reserve capacity so it can be sufficient for all components.


This is one of the most crucial factors you need to check before laying your eyes on a particular battery. Your car has a limited space in which it has to fit various electrical parts. Thus you cannot choose a battery without giving any heed to the size of the battery tray your car has for an additional one.

Hence, measure the dimensions of the space in which you want the additional battery to reside and then look for a device that is closest to those measurements.

Maintenance of the Battery:

Most of the batteries that we have discussed above are maintenance-free. They have a 100% sealed casing that ensures no spillage or leaks. It does not require you to check the water levels or fill it occasionally. Thus, it requires no effort from your side.

Some Batteries have an unsealed casing and require you to check their water levels quite often.

It is a personal choice, but of course, a maintenance-free design means that you would have one less thing to worry about.

Vibration Resistant:

Vibration resistance helps to keep the battery in its place. Vibrations cause the battery to undergo shocks, which can damage the battery’s interior, and it will not perform well. Moreover, a vibrating battery will make noise.


When we invest in a particular product, we want it to last long. The lifespan of a battery generally depends on the amount of its usage, but every battery does have a rough figure of how long it will last if it is taken proper care of. So, check the expectancy out before buying a particular battery. Another thing to look out for is a warranty, which aids you if you face a problem with your unit.

Frequently Asked Questions (FAQs):

How many watts are suitable for a car stereo?

First, you need to calculate the wattage of your audio system. This will give you an idea of the output of power that the stereo requires to run. Then, invest in a battery that meets or exceeds that wattage.

For example, if you have an audio system with a wattage of 1600, you would need to buy a battery that meets that rating.

Why is the case of my battery bloated?

The case of the battery can be bloated due to several reasons. A buildup of gases within the battery can cause it to bloat. The battery is either being used for a long time and might need to be changed, or the battery can be overheated.

If you see any type of deformity in the case, take your car immediately to a technician. Get it checked!

With so many car audio batteries on offer, picking the right battery with the ideal features is vital. That’s why you need to know the critical features to look for before spending your hard-earned money on a poor battery.

What does reserve capacity mean?

When picking a car audio battery, you must consider its reserve capacity. The reserve capacity shows how long the battery will deliver power when it is not being charged.

What are the advantages of using a car audio battery?

The car audio battery has lots of benefits over the traditional car battery. First, these batteries are cheaper than traditional batteries. Secondly, they deliver sufficient power that your car sound system requires for optimal performance.

Also, they come in various sizes, which means they will fit in different cars. Besides powering your stereo system, these units also power various electrical components onboard. Unlike traditional batteries, the car audio batteries power your sound system when the engine is not running.

How can I tell that my car audio battery needs replacement?

Different car audio batteries have different lifespans. As a result, you should ensure you acquire a durable battery that will offer you many years of good use. Most car audio batteries last up to 6 years. But just like many other types of batteries, it will weaken with time and fail. But how will you tell that your car audio battery needs replacement?

Which battery should I install for my car audio system – redtop or yellow top battery?

This depends on your preferences and needs. Redtop batteries are great for starting the car engine as they deliver high bursts of power to the ignition. These batteries are also spillproof and maintenance-free.

On the other hand, yellowtop batteries are ideal for powering electrical components. These batteries are also convenient to use as they can be mounted in any position and provide excellent deep-cycle and cranking power.

What are the different types of car audio battery?

Similar to many other types of batteries, car audio batteries have a variety of types to select from. Different car audio batteries are best suited for various sound systems. So, you need to know the different types available and choose the one that best suits your car sound system.

Some of the most popular types include deep cycle battery, calcium-calcium battery, lithium-ion battery, wet cell battery, and valve-regulated lead-acid battery. A deep cycle battery is the most preferred, while lithium-ion is the most expensive. On the other hand, wet cell batteries are spillproof, while lead-acid batteries are entirely sealed.

In a Nut Shell:

Finding the best car audio battery for your car is vital as it will not only help you to reduce strain on your car battery but also provide power for other electronics in the car. Select a durable and high-performing battery for many years of use.

Take your time and consider the features each battery has. It should also be of the right size and comprise the right cold-cranking amps and watts.

Our list features some of the best car audio batteries that you can lay your hands on. Just ensure to go through every one of them before picking one that meets your needs and budget.

It is logical if you buy a second battery and use it only to power your audio system. This will reserve extra power in your car, and you won’t have to worry about the music system giving up during a ride.

Before selecting a particular product, it is always smart to make a checklist to assess the factors on which you want to judge a product. Then, choose one that checks most of the boxes on your list. You should always buy from a reliable source to eliminate getting a defective, non-returnable product.
