Best Car Audio Batteries – Top 10 Reviews with Buying Guide

Your car stereo system is one of the most important accessories and it demands for constant power surge and this is where a car audio battery comes in handy. A good car audio battery should be in line with the modern technology and it should be backed with essential features. This will ensure that your car sound system is on point to hit those numbers regardless of whether it is a short or long car adventure.

Types of Car Audio Batteries

Car audio batteries just like other batteries come in different types and what works in one car audio system may not work in another. This is why it is important for us to highlight the various types to help you determine the right kind for your car audio.

  • Calcium-Calcium:  This battery is made up of calcium plates which are charged separately. The key element in this battery is the use of calcium which helps to reduce the rate of discharging by reducing the amount of fluid that is lost.
  • Deep Cycle: The deep cycle battery is highly durable and comes with thick plates which help increase its capacity charge. It, however, has a high discharging rate.
  • Wet Cell: This battery is spill-proof and the fluid doesn’t need to be topped up. Its plates are suspended in the fluid but they are well insulated. It is mainly regarded as maintenance- free battery.
  • VRLA (Valve-Regulated Lead-Acid): This battery comes with safety valves and lead acid. It is also sealed completely meaning it can only be replaced in case of any malfunction. This mats that helps to reduce internal resistance.
  • Lithium-Ion (Most expensive): This battery stores a lot of energy but it’s a bit higher on the price spectrum. It, therefore, has a limited use mostly in electric automobile although today a good number of vehicles use this battery.

Selection Guide; Things to Consider When Choosing the Best Battery for Your Audio System

Having gone through our extensive review, these factors that we have highlighted below will help make an informed decision even as look at different variations offered by manufacturers.

Cold-Cranking Amps (CCA) and Reserve-Capacity

This is the ability of the battery to power the audio system in cold temperatures. A battery’s CCA should match the amount of watts produced and the higher the number of CCA the higher the amount of power produced. As such you should always look out for these two elements.

Size and Fitting

The size should fit properly in the battery tray provided. You should check the dimensions provided in the user manual to see if it will fit. The positioning of the terminals should also be correct. This is important because just as with your primary car battery, loose audio battery will results into vibrations which will eventually damage the battery itself and consequently the audio system. 

Care and Maintenance of the Battery

Ideally, your battery will either require some little maintenance or no maintenance at all. Those that require little maintenance comes in unsealed design where you can add water occasionally before you can eventually replace them.  Those that don’t require maintenance, on the other hand, are completely sealed allowing for only replacements in case of any damage.

Battery Age

Just like other batteries, car audio batteries power units can get damaged if they are not charged for some time. Any battery that has exceeded six months since it was manufactured should be avoided as it is likely that it has lost some power.

Price of the Battery

They are two major divisions of batteries that determine the price tag; wet- cells and dry-cell units. The dry-cell units are more expensive than the wet cell and they serves longer. Wet-cell, on the other hand, are inferior to the dry cell only that they power the stereo system a bit faster when compared to the dry cell.

The Bottom Line

Before you settle on any battery for your car audio, you need to look out for the one that will give you optimal performance. A car audio battery is a crucial accessory as it relieves the main car battery of the burden of powering your sound system. Picking a durable and high performing one will assure you of many years of short and long trips with the desired level of entertainment.

The car audio being an important accessory of the car, having a reliable source of power will come in handy for a more enjoyable road trip. We hope this guide has helped you avoid the pitfalls on your search for the best battery for your car audio.
