What Are the Benefits of Having a Best Car Audio Battery?  

Put less strain on your car’s main battery 

Your car’s battery is powerful, but it’s not nearly powerful enough to provide the extra power needed for aftermarket audio systems. It should be able to power such a system for a while, but you run the risk of having a drained battery for doing so. Because of this, it’s recommended to have a second battery installed.   

Having a dedicated car audio battery will allow your aftermarket car stereo system to run at its optical performance without putting you at risk of a drained battery or affecting your car’s overall performance. 

No worries about listening to music while parked 

Anyone who’s ever made the mistake of listening to music for hours while parked will tell you that it can fully drain your car’s battery if you’re not careful. But, if you have a dedicated car audio battery, you can listen to music for as long as you want, even when you’re parked and not doing anything else.  

It’s a cheaper alternative to capacitors 

Installing capacitors is another way of providing power for an aftermarket car audio system. However, they’re expensive to install. They also take up a lot more space than a spare audio battery. 

Types of Best Car Audio Battery

There are three main types of best car audio battery used these days.   

The first is the wet lead-acid battery, which is the cheapest and most common option. This type of battery also requires regular maintenance as you’ll have to top it off with distilled water. Otherwise, the battery will end up suffering damage. This type of battery is also prone to spillage, which is why, despite its popularity, a growing number of people are starting to consider other options.   

The second type of car audio battery is the gel-cell battery, which uses an electrolyte gel.   

Gel-cell batteries are considered safer compared to lead-acid batteries. This is because they are designed to be sealed and maintenance-free. The gel itself is also resistant to the constant vibration caused by the car running.   

The third and last type of car audio battery is the AGM battery.  

AGM batteries are similar to gel-cell batteries in that they are both sealed and designed to require zero maintenance. However, AGM batteries are cheaper compared to gel-cell batteries because they still use lead-acid. The only difference is the sealed design that helps minimize the risk of spillage.  

What Features to Consider in a Car Audio Battery 

There are three main factors to consider when shopping for the best car audio battery for optical performance. This includes its power ratingbattery lifeand environmental protection

  • Power Rating  

The power rating is pretty self-explanatoryYou’ll have to choose a car audio battery that’s capable of powering your entire stereo system.   

Keywords to watch out for include amperage, amp-hoursand cold-cranking amps 

  • Battery Life  

There are several factors that affect how long a car audio battery can last. This includes how often it is used, how you charge it, as well as the kind of temperatures that it is subjected to often.   

But, as a general rule of thumb, the larger the battery bank, the better.  

  • Environmental Protection 

Making sure that your car audio battery is built to withstand its usage environment is key to getting a good car audio battery.   

Shock and vibration protection should be a given. The ideal car audio battery should have both. Heat and cold proofing, as well as water-resistance or water-proofing, are also huge pluses for an extended lifespan.  

The Best Car Audio Battery -- Our Top 5 Picks! 

Affordable and best don’t always go together, but it sure does with the Kinetik HC600 BLU AGM Power Cell!  

The ideal car audio battery for systems that don’t require more than 600W of power, the HC600 is perfect for budget-conscious buyers. However, despite its relatively low asking price, the HC600 BLU AGM is far from cheap. In fact, it’s vibration-resistant and resistant to heat with a high-current power output, as well as a lightweight design.  

For a dedicated car audio battery, the Kinetik HC600 is as low as we can recommend price-wise.
