Best Car Audio Battery 2020 Review and Buying Guide

A car battery forms the soul of a car. It powers many functions including windows, door lock systems, audio system, and car lights. Waking up to a dead battery can be a nightmare to any driver regardless of the type of vehicle.

Car audio batteries enable the sound system to deliver its best potential. Music from the system becomes louder, deeper, and clearer. When the battery is added as an auxiliary battery, it helps to prevent drain on the starter battery. Thus, you reduce the chances of experiencing a dead starter battery. It also helps to avoid other electrical issues, including dimming headlights and slow windows.

While it’s a fact that no battery lasts forever, a car audio battery of excellent quality, and one that is well-maintained, will give you satisfactory service. This guide focuses on finding the best car audio battery on the market.

Starting from our #1 car audio battery, we now review all the six products systematically.

1. ACDelco ACDB24R

We kick off our review with a car audio battery from one of the most trusted brands in the car battery industry. The ACDB24R is a 12V battery with 70 minutes reserve capacity and 390amps cranking amperage. It weighs 28.8 pounds. The battery has unique features that showcase ACDelco’s relentless effort to maintain leadership in the industry.

Features of ACDelco ACDB24R

  • Absorbed Glass Mat (AGM) design: ACDelco has used AGM technology to seal the battery completely and eliminate chances of spills or leakages. The battery’s design is such that the electrolyte is permanently contained in the glass mat separator. This is unlike other battery designs where the electrolyte moves from cell to another, which leaves an opportunity for spills or leakage.
  • Valve-controlled gas recombinant technology: The battery’s leak-proof pressurized system continuously prevents damage due to acid. It also ensures that the battery doesn’t dry out. In effect, the system helps to maintain the life span of the battery. Besides, automatic discharge is reduced significantly. The stereo battery can stay charged for long even when stored.
  • Higher cranking amp: The starting power of a car battery goes down as time passes, especially during the cold seasons. Higher cranking amp means more engine starting power. With this ACDelco battery, you will be confident that your engine will start without any problems.
  • Silver/calcium alloy for increased conductivity: Besides using positive and negative calcium plates (these reduce the rate of power discharge when the battery is not in use) the ACDB24R features a silver/calcium alloy that acts as a cathode for reducing internal resistance and optimizing the battery’s conductivity. This implies increased audio power back up.

Pros

  • 100% leak-proof and spill-proof design
  • Outstanding cranking power
  • Maintenance-free operation; you don’t need to keep adding water
  • Reputable manufacturer
  • The battery lasts 3 times longer than traditional car batteries

Key considerations to make when choosing the best car audio battery

Investing in the right brand and type of car audio battery is critical to achieving the audio quality goals one has set to achieve. Whether you are replacing your factory battery or adding an auxiliary battery, there are a few factors you need to consider to ensure that you make an excellent choice.

Reserve capacity (RC)

This is the length of time (in minutes) that the battery can provide 25 amperes at 10.5 volts.

Why is reserve capacity important?

When a vehicle starts, the battery pushes out 25 amps at 10.5 volts until the alternator starts to run. As the alternator assumes responsibility to power the engine, the battery steadily provides the same amount of energy to other electrical accessories such as lights and wipers. If the alternator is not in good condition, the car runs solely of battery power. A battery with good reserve capacity enables the car to continue running. You don’t get stuck just because the alternator isn’t working. Besides, the battery can drive the audio system for longer when the engine is off.

Starting power

A battery’s cranking power is indicated by two ratings - Cranking Amps (CA) and Cold Cranking Amps (CCA). CA refers to the energy needed to start a vehicle at 32 degrees Fahrenheit. CCA refers to the battery’s ability to start a car at zero degrees Fahrenheit. Cranking Amps are relevant for hot climates while Cold Cranking Amps are important when choosing the right car audio battery for cold climates.

Redtop versus Yellowtop car audio battery

Redtop batteries produce a high burst of starter energy, last a longer time, and recharge quickly. They are mainly used as starter batteries. While the batteries can work with factory audio systems, their design doesn’t support multiple electronic devices.

On the other hand, Yellowtop batteries are designed to work with car speakers, amps, and non-audio systems and devices including cameras and GPS. In addition, most of these batteries are vibration-resistant and last longer than redtops. Thus, Yellowtop batteries can be installed in many suitable locations within the car.

Sealed versus non-sealed batteries

Non-sealed batteries have caps that allow for addition of water to cool the battery. They are the better option for places that experience high temperatures.

Sealed batteries require less maintenance. It’s challenging to add water into sealed batteries so they are not ideal for use in warm climates.

Battery lifespan and warranty

A battery’s lifespan depends on its use. Generally, good car audio batteries last between 3 and 5 years. The sooner it dies, the sooner you have to replace it. You want to choose a battery that lasts long. Checking the age of the battery is a crucial step. It’s recommendable to buy batteries that are not older than 6 months from the manufacture date.

Also crucial to consider is the manufacturer’s warranty. On average, replacement warranty for car audio batteries is 3 years.

Battery size

Can the battery fit in the desired mounting space? Some batteries only fit perfectly in specific vehicle models. Others are universal and fit in most modern vehicles. It is inherent to choose the best fitting car battery size to avoid issues of incompatibility and the need to make adjustments to the installation space.
