Looking to improve your car’s sound system? A separate car audio battery can keep you rockin’ without having to worry about draining too much energy from your car’s main battery. If you spend a lot of time in your vehicle you might be looking to upgrade your audio/infotainment setup. While planning to set up a powerful stereo system don’t forget that you’ll need a power source for all that equipment. That’s where a dedicated car audio battery can come in handy. 

If you’re looking to upgrade your car’s audio/infotainment system remember — additional compenents that draw power, like a sound system, will drain your existing battery quicker and affect the overall performance of other electrical parts of your vehicle, like headlights, sensors, and more. 

To help prevent power loss from happening, you should consider investing in a second car battery that can let you enjoy your tunes to the fullest. Let’s take a close look at our first product choice and slowly move down our list, after which there will be a helpful buying guide of everything you need to know about car audio batteries.

Buying guide: Car audio batteries

Although most car audio batteries might look the same, they really aren’t– each model has different specifications (amperage, output, load, and more) that set them apart. To help you find the right car audio battery for your vehicle, we’ll be looking at some important things that you should keep in mind when shopping around. Are you ready? Let’s go!

Benefits of using a car audio battery

Before we proceed, you should know why a car audio battery is so important for your vehicle.

  • Do you enjoy listening to music in your car? A regular battery can’t provide you with much time before it runs out, but don’t worry– an extra car audio battery can last much longer without so much as a problem
  • Your car’s battery powers every factory component in it, so there isn’t really any extra energy left for anything else. With the assistance of a car audio battery, you’ll be able to use your upgraded sound system without any reduction in vehicle performance
  • Most car audio batteries are available for a pretty reasonable price tag, and this means that almost everyone should be able to afford one
  • Unlike amplifiers, car audio batteries are pretty simple to install and don’t require any form of professional background experience to do so

Different kinds of car audio batteries

Car audio batteries, just like other accessories, are available in several different types. Knowing the difference between each kind can certainly make the entire selection process a lot easier. 

Lead-acid audio batteries

These forms of batteries are usually incredibly heavy and have a high-energy output. Even though they come at a pretty affordable price tag, most users tend to avoid them. Wondering why? Well, the entire structure contains lead plates in an electrolyte solution, so for them to function properly, you’ll need to top them off with distilled water every once in a while. If you happen to forget to do this, you might damage the battery, and in some instances, the battery might even cause damage to your sound system as well.

Gel-cell audio battery

This particular car audio battery uses an electrolyte gel instead of distilled water, and it doesn’t require any maintenance or have any significant problems like lead-acid batteries do. One of the disadvantages of the gel-cell audio battery is the higher price tag, but many consumers are willing to spend a few extra bucks for added safety.

AGM audio batteries

Similar to the gel-cell battery, this specific model is completely sealed and doesn’t require any special maintenance. They typically last longer than most conventional batteries and are also environmentally friendly. 

Lithium audio batteries

This is certainly one of the most commonly used audio batteries in the entire world. It’s exceptionally lightweight and delivers a more steady voltage to your audio system, but lithium audio batteries aren’t as durable as other models and they do require protection from overcharging. They’re generally able to survive up to 1,000 charging cycles, though this number can vary depending on the specific model you’re looking at.

How to find a high-quality audio battery for your car


The first thing that you should do is check whether the specific audio battery you’re thinking about buying has enough power for your car system. Here are several different things you should examine:


Look for an audio battery that can meet the overall power rating of your car stereo system.

Cold-cranking amps

The cold-cranking amps indicate the ability of the battery to work under freezing temperatures– remember, the higher, the better.

Amp hour

This specific measurement tells buyers how much amperage a battery can offer for precisely one hour.


After you look at the power, make sure to confirm that the audio battery will fit in your car. You’ll see the size dimensions of each model mentioned somewhere down in the product description, but if you have trouble finding it then get in contact with the company’s assistance team.


A car audio battery is a rechargeable power unit, and because of this, it tends to lose its strength over time. This is why you should pay attention to the manufacturing date of the battery–  try to find a model that hasn’t been sitting on the shelf for more than six months.


The last (although certainly not least) thing you should look for when purchasing a second battery is its warranty. Most car audio batteries typically have the following warranty– “24/84.” The number 24 means that you’ll be able to replace the battery within 24 months, while the number 84 means that you have a service guarantee of 84 months.

Don’t forget to carefully review the whole policy (the document posted by the manufacturer) before making your final purchasing judgment. Two important things that are a big no-no when it comes to car audio batteries are low water levels and incorrect setup. 

Car Audio Battery FAQs

Q: How can I successfully install my new car audio battery?

The entire installation procedure will vary depending on the particular model you have. We advise you to read the entire instruction manual before you start, and if you don’t think that you can perform the whole process, then don’t even try– just call a professional. Luckily, most technicians don’t charge a lot of money for this job.

Q: Where should I place my second audio battery?

It’s important to look for a safe place for your car audio battery. If there’s no extra space in the engine compartment, then be sure to check out other places like the trunk, glove box, or even below the passenger-side seat.

Q: How can I fill a lead-acid power battery?

Filling a lead-acid battery is relatively easy. First, make sure that the car and audio systems are all turned off. Next, pry off the cover of the power battery and take the cell vents off. Lastly, fill the cells with water and place the rubber caps back on.
