Best Car Audio Battery Buying Guide

In the following section, we will look at some of the main things that you should look out for when you are buying a car battery for your sound system. Next, we will go into more detail about the benefits of a car stereo battery ahead of the other methods you could use to power your vehicle’s audio. And we will then weigh up Redtop and Yellowtop batteries to decide which one is best. Finally, we have our frequently asked question (FAQ) section, which is there to answer some common queries which you may still be having.

What to Look for When Buying a Car Audio Battery

Before you rush out to get the car battery which you think is ideal for your vehicle, you should stop to make sure that this is actually the case. After all, you don’t want to shell out such a large sum of money, only to find that it doesn’t meet your needs. So, here are a few things to look for.

  • Size

First thing’s first; you should check the size of the battery to ensure that it is compatible with your vehicle. It needs to fit the specific make and model of the vehicle you own. Check out the product description and manufacturer specifications for more information. If you have a specific place in mind where you want to mount the battery, now is the time to start measuring. You don’t want to have to go through the effort of sending back the battery after choosing the wrong size.

  • Battery Reserve Capacity

The reserve capacity of the battery indicates how long power will be provided while it is not being charged. Ideally, you should be looking for a figure of at least a couple of hours, especially if you plan on using the car’s audio without the engine running. If you are powering more accessories, you probably need a battery with a higher reserve capacity.

  • Maintenance

Many of the batteries which we discussed above describe themselves as ‘maintenance-free’, which obviously makes your life a lot easier. Essentially, this means that you don’t have to add any liquid for it to continue working. The majority of these batteries are sealed, so you don’t have to worry about opening them up to conduct any work on them.

  • Handle or Loop

This may seem like a little thing, but if the battery has a plastic handle or loop, this makes it so much easier to lift and carry around. Remember, they can be quite heavy and difficult to wield around easily. It also helps when you are trying to lower the battery into an engine compartment which is tightly packed together.

  • Easy to Mount

You may be limited by the number of locations you can mount your car audio battery, particularly if you are driving a smaller vehicle. So, look out for spill-proof and sealed batteries which you can mount in a wide range of different places. This way, you don’t have to worry about battery fluid leaking out if you have positioned the battery in a more unorthodox position.

  • Vibration Resistance

If you are driving a car with poor suspension or you plan on driving on rougher and bumpier surfaces, it is especially important that you choose a car which offers a decent degree of vibration resistance. Otherwise, there is a greater risk that the battery will become damaged in some way when you are driving along.

  • Battery Life and Warranty

When you spend quite a lot of money on a product such as this one, you want a better idea of how long you can expect it to last. The amount of time that you use it for is obviously going to make a difference, but it is good to have a rough guideline which tells you how many years of use you can expect to get. All batteries have a limited shelf life, but some are obviously more limited than others. The warranty is another issue which is worth bearing in mind. The longer the warranty lasts, the longer you don’t have to worry about is going wrong without being able to get a replacement. A replacement warranty of around three years is usually a pretty good length of time.

  • Customer Reviews

When it comes to specialized car parts like batteries, the customers who purchase these products are usually fairly knowledgeable, so you can get some good information from reading the customer reviews. Often, they include technical information and their own experiences while using the battery in their vehicle. And unlike other products, there are usually fewer reviews, so you don’t have to spend a long time scrolling through hundreds and hundreds of them. As always when you are reading reviews, make sure that you read the ones which cover the middle ground rather than only listening to the best and worst of the bunch.

  • Price

Obviously, the price shouldn’t be the only factor to take into account when you are choosing, but many customers are looking for a cheap car audio battery. However, you don’t want to go for a low price if it is a complete sacrifice of quality. Otherwise, you are likely to need a replacement sooner, and the money you saved will probably end up going towards this.

Benefits of Using a Car Audio Battery

Before you settle on getting a car audio battery, you probably want to know some more about what benefits this will provide to your vehicle. Well, here are a few of the top plus points for you to bear in mind.

  • Give Sufficient Power to Your Car’s Audio System

Pre-installed car batteries are only designed to power a car’s basic functions with not much left over. The remaining power of a factory-installed battery is not enough to power a sophisticated car audio system. When you don’t have enough power, this could lead to electrical issues around the vehicle such as a dimming of the headlights or a reduction in speed of the electric windows. Often, it will mean that the expensive audio system which you bought does not sound as good as it is supposed to. A second battery gives you plenty of reserve capacity to power the audio, and you can also place it close to the amplifier for improved performance.

  • More Affordable Option

The other main option to power your car’s audio system is to get a capacitor, which is useful in providing sudden bursts of energy when needed. However, it is the significantly more expensive option, and some people debate whether or not getting one is worthwhile as they do a similar job to second batteries. Another battery will also take up a lot less space in your vehicle for the same amount of electricity storage.

  • Usable for Other Purposes

When you add an additional battery to your car, you can also use it to solve other power issues around your vehicle. Since it is a permanent source, it is always there whenever you need it. So, if you have been having other issues around your car such as dimming headlights when you are playing your music, this no longer has to be a problem. Often, people get a second battery for their vehicle when they go out camping a lot and need a power source to charge all their accessories. If you don’t have a second battery, you are likely to run down your only source of power and end up with a flat battery when you try to drive away the next morning.

  • Available in Different Sizes/Easily Installable

We have already talked about the importance of choosing a battery which is the right size for your car, but there are plenty of different options, so you are bound to find one that is right. Also, most of the batteries above can be mounted in a range of different locations, so you can make it fit around your other components. Work out the reserve capacity you need on your second battery based on how long you plan on playing your music in an average session.

  • Power Your Audio While You Are Stationary

If you like to play your car’s audio system when you are parked up and the engine is not running, a second battery may well be a worthwhile investment. This way, you have hours of extra juice without having to worry about powering down your main battery. If you use the battery that your car came with, it may only be able to power your car’s audio with the engine off for around an hour or so.

Redtop or Yellowtop for Car Audio?

The choice between a Redtop or Yellowtop battery for your car audio needs is one which comes back to personal preferences and your audio need. Never mix the two unless you can connect them both separately. So, let’s discuss the advantages of disadvantages of the two varieties in more detail to help you make your mind up.

  • Redtop

Redtop batteries are made for engine starting and can be used in automobiles or RVs. This AGM battery will offer a high burst of power to the ignition which ensures that start-up is reliable. On the plus side, it provides a fast recharging time, as well as a long lifespan. It is vibration resistant and will mount in a wide range of positions. It is also maintenance-free and spill-proof. You can expect the battery to start at any temperature. However, it is better in a vehicle without significant electrical loads.

  • Yellowtop

Yellowtop batteries are made for cars which have been enhanced with a range of electrical features including amps, speakers, GPS systems etc. It offers you deep-cycle and cranking power and you can mount it in a range of positions. The design is vibration-resistant and almost maintenance-free. If you have a vehicle which needs audio and visual power exceeding 250 watts, this is a great option. On the downside, it is comparatively expensive.

Best Car Audio Battery FAQ:

Q: How does an automotive audio battery work?

An automotive audio battery works in the same way as a traditional car battery, but it is dedicated to powering your vehicle’s audio needs. Factory-installed batteries can power basic audio functions, but a high-end audio system requires extra juice to work effectively. Amplifiers are especially power-reliant and will not work at their optimum level without an extra source of power. If the car is spreading around its power too thinly, this will negatively impact some of the other electrical features around the vehicle such as the windows and headlights. A second battery allows you to double your stored power, so you can enjoy your audio system without negatively impacting the other features around your car. It gives you plenty of reserve amperage, particularly if you place the battery very close to the amplifier. Batteries come in a range of different sizes and power capacities, so you can choose the one which comfortably covers all the functions in your vehicle. Generally, installing a second car battery should be a relatively straightforward procedure. The most common location is in the trunk as you are unlikely to be able to put it in the engine without making some pretty serious modifications. Otherwise, you could put it under the load tray or in the passenger compartment. Essentially, you want to keep it from getting too hot, which could prove to be a problem for the battery. Depending on how much space you have available in the car, you may have to choose a battery which is physically similar to the original one which you already have. Often, they are wired into the vehicle, so your second battery can continue charging while you are driving. A high-amperage on/off switch then allows you to switch to the second battery when you are parked to stop the main one from draining. However, you need to remember to flick that switch to ensure that the right battery is being used at the right time!

Q: What’s reverse capability?

The reserve capacity of a battery tells you how long the battery will last at a specified current draw. It is defined as the number of minutes which a fully-charged 12-volt car battery will continue providing 25 amperes at 10.5 volts while stored at 80 degrees Fahrenheit until the voltage decreases. If the vehicle is solely relying on battery power, this tells you how long you can continue running the battery until you need to recharge it.

Q: How much does car safety depend on the battery?

Your car’s basic functioning relies heavily on the battery. A standard car battery should last for around six years, but this largely depends on how well you treat it. When the engine is off, your car will draw power directly from the battery, which will cause it to drain quicker. There are usually some obvious symptoms when it is time to replace your car battery. The most obvious is that the battery warning light will be illuminated! Another sign could be that the vehicle electronics suddenly stop working without any explanation. Since batteries are full of chemicals, you should make sure to dispose of the old ones in the proper manner.
