7 Best Car Audio Batteries – Reviews & Buying Guide

Best Car Audio Battery

If you own a powerful car audio system, then connecting the amplifier directly to your car battery is not a good idea. This is because your main car battery may not have the necessary amperage to power such a demanding audio system.

Furthermore, your car battery’s purpose is to start your engine and not power an audio system. This is where the car audio battery comes into play.

As its name suggests, the car audio battery is a battery dedicated exclusively for your car audio system. A good car audio battery is usually heavy-duty, has a low discharge rate, and can send a high amperage to power demanding amplifiers for long periods of time.

Without further ado, let’s check out our review and see which model you need to buy.

How to Buy the Best Car Audio Battery

How to Buy the Best Car Audio Battery

#1. Size and Compatibility

First and foremost, you must consider the size of the car audio battery. You will need a place to install it inside your vehicle so it must not be too big to fit.

Additionally, remember that generally, the bigger the car audio battery, the more performing it usually is. However, there are exceptions to this.

Moreover, you must ensure whether the battery is compatible with your vehicle. You should be able to easily connect the battery to your audio system.

#2. Dedicated or Dual-Purpose Audio Battery

The dedicated car audio battery will supply only your audio system with power. It was not and cannot be used to power your vehicle engine at the start. For this, you will need a separate car battery.

There are many advantages to having a dedicated car audio battery for your audio system. The most important one is that you do not share power with your vehicle with a dedicated battery system. This means that your audio system will get all the power and can work more efficiently.

Coupled with the dual-purpose audio battery, it will not only connect to your audio system, but also to the alternator. This means that when you start your vehicle, it will use this battery to power the engine on.

If you choose to go with a dual-purpose audio battery, then always go with a heavy-duty and high capacity battery.

#3. CCA and Reserve Capacity

The CCA or Cold Cranking Amps is a measure of how resistant the battery is in low temperatures. The higher the CCA value, the more resistant it is too low temperatures, and you will be able to use this type of battery in colder environments.

So, if you live in a cold weather, then it is best to go with a model that has a high CCA value. If not, then this is not very important to you.

When it comes to the reserve capacity, then this is how long the battery can send a current before it loses 50% of its charge. In short, the higher the reserve capacity, the more heavy-duty and performing you can assume the battery to be.

#4. Handle or Loop

The handle at the top of your car audio battery is important, especially if you plan to carry it around. It will make it more portable and easier to lift.

If portability is not important, then you should not worry much about the handle.

#5. Battery Life

Most manufacturers will tell you the lifespan of their batteries. This value is usually measured in years and the longer, the better.

We recommend that you go with a car audio battery that has a battery life of at least 3 years.

This will ensure that you get longer usage out of it, especially considering that this is not a small investment and the car audio battery is usually quite expensive.

#6. Maintenance

Some of the best car battery for the sound system on the market are usually maintenance-free. This means that once you install it, you do not have to perform any type of servicing on it.

On the other hand, some models like wet-cell batteries require frequent water replacement for it to work in tiptop condition.

Whether or not you need to perform maintenance on your battery will depend on the brand and type of car audio battery that you purchase. You will need to read your manufacturer’s instruction manual about the maintenance interval in case your battery needs it.

#7. Vibration Resistance

If you plan to listen to your audio system at high volumes, then you will get a lot of vibrations. Especially if you have a powerful bass system on board. Therefore, you must ensure that your preferred battery is vibration resistant to prevent damage.

Also, there are many car audio battery models that have a special technology inside that protects them against vibrations. This is especially true for AGM batteries that are reputed for being highly vibration resistant because of the way the fiberglass mats inside are stacked.

#8. Price

The price is another important consideration, especially if you have a small budget to spend on a car audio battery. However, keep in mind that the quality model should normally cost you around $200 on average, so this is not a small investment.

Our recommendation is simple.

Make a budget and try to find a car audio battery that revolves around that your budget. This is important because prices can quickly get out of hand with the car audio battery.


If you have a performing audio system in your car, then you absolutely must have the car audio battery installed. It will offload the electrical load from your main car battery and supply your audio system with a decent power source.

Furthermore, you will enjoy a better sound quality by using a secondary car audio battery for your music because it is usually more heavy-duty and can output more amperage. This is especially important if you have a power-hungry amplifier system.

In our car audio battery review above, we have listed some quality models. If you still do not know which car audio battery to purchase for your vehicle just yet, then don’t worry. Read the review again.
