Advantages of Car Audio Batteries
One of the biggest advantages of a car audio battery is that it takes the load off the main battery so that the car’s performance is not reduced. It offers a great amount of reserve power to let you enjoy your favorite songs continuously on a long journey without any interruption.
Moreover, with a second battery, you can also listen to music for a longer time when the car engine is not running. A car audio battery is also a great option for those who often go car camping where you need to use your car accessories without the engine running.
Car audio batteries are also helpful if you usually let your car sit for two weeks or more which otherwise can completely drain the built-in battery. You can also replace your car’s existing battery with a powerful car audio battery.
High-quality car audio batteries are long-lasting, vibration resistant, corrosion-resistant, have a high energy density, and use the latest technologies for the best performance.
Another great thing about car audio batteries is that they are a cheaper option when it comes to solving power-related car issues. They also take less space compared to other options such as capacitors. Moreover, they come in different sizes so you can easily find one for your car.
Types of Car Audio Batteries
Car audio batteries come in various sizes, shapes, and types. Different batteries use different technologies and have different working mechanisms. Before choosing a battery, it is wise that you know what different types of batteries offer.
Flooded lead-acid batteries, more commonly known as wet lead-acid batteries, are among the most common types of car audio batteries. A lead-acid battery consists of lead plates that are submerged in a sulphuric acid electrolyte. These batteries cannot produce voltage and work by storing charge from some other source. The amount of charge they can store depends on the size of the plates and the quantity of electrolyte.
These batteries are quite inexpensive but require maintenance. You need to top up the battery regularly with distilled water to keep it running. However, to do this, the battery must be unsealed, which can cause spillage. This also makes these batteries a bit dangerous because they can damage your skin if you come in contact with them.
If you are looking for a car audio battery and have a tight budget, a lead-acid battery can be a good option.
AGM or Absorbed Glass Mat batteries are quite popular these days. AGM is an advanced technology that offers a great amount of power for all your audio system needs.
These batteries are basically an improved version of lead-acid batteries as they are completely sealed but contain lead-acid inside. They don’t require any maintenance such as topping up and because they are sealed, there isn’t any risk of chemical spillage. Moreover, they don’t discharge quickly and have a quick recharge rate.
AGM batteries use a high-quality thin fiberglass mat that is tightly packed between the plates. This makes the battery vibration resistant and long-lasting. The fiberglass absorbs the electrolyte and stores it in a dry form, which helps in preventing spillage. The fiberglass then transfers the acid to the plates as needed to keep the battery running.
If you have a car audio system that has high power demands, an AGM car audio battery is your best option. Moreover, you should also opt for an AGM battery if your car has various electronic equipment and you use them often.
Lithium-Ion batteries are a bit expensive but have high energy density and hence, have a long runtime. Moreover, these batteries have a low self-discharge rate and don’t need much maintenance as they are fully sealed. These batteries can produce high voltage and are ideal for high-end car audio system that has high power demands.
Key Features of High-Quality Car Audio Batteries
Before you purchase a car audio battery, you should be aware of the characteristics and features that a high-quality battery possesses.
The output of a battery is usually determined in terms of its amperage, amp-hour, voltage, wattage, and cold-cranking amps (CCA) ratings. Amp-hour reflects the capacity/run-time of the battery as it represents the total number of hours for which the battery can continuously supply the specified amount of current.
Most high-quality car audio batteries are 12 volts batteries while other ratings such as amp-hour and amperage vary from battery to battery.
Before purchasing any car audio battery, you should evaluate how much power does the car audio system needs and whether the battery has enough power to handle it. Moreover, if you install a high voltage battery with a low-quality audio system, it can get damaged due to high power output.
Vibration and Shock Resistance
High-quality car audio batteries are vibration and shock resistance which helps in prolonging its life span. This means the battery won’t get damaged when you drive the car on rough roads.
Self-discharge means that the charge stored in the battery reduces even when it is not running, which decreases its capacity. The self-discharge rate of high-quality car audio batteries is quite low, which means they can run for a longer time.
The life of a battery usually depends on the temperatures it operates in, the frequency of usage, and its charging mechanism. Two main factors that reduce the battery life is the corrosion of plates and quick evaporation of electrolyte. Needless to say, top-notch car audio batteries are durable, can withstand high temperatures, and have a long life span.
Fully sealed batteries like AGM batteries can be mounted in almost any position as they are spill-proof. Since lead-acid batteries are not completely sealed and require water filling, they should be mounted in a specific position.
Q: What are some of the most popular brands of car audio batteries?
A: Although many brands are offering car audio batteries, some brands are more popular due to their strong reputation and high-quality products.
OPTIMA is one of the best-known brands when it comes to batteries. The brand is particularly famous for its innovation. Not only is it the first company to produce maintenance-free lead-acid batteries but also the first one to introduce AGM batteries for vehicles. The brand still continues to surprise the world with its innovations.
XS Power is another popular name in the car battery industry. The company has been offering different kinds of high energy density car batteries since 2005.
Q: Do car audio batteries come with a warranty?
A: It depends on the manufacturer but most high-quality car audio batteries do come with a warranty. The duration of the warranty varies from brand to brand.
Q: What are the standard dimensions of a car audio battery?
A: There are no standard dimensions and different car audio batteries are available in different sizes. However, before you purchase a battery, it is important to consider the size of the battery and the space you intend to fit it in.
Q: Do car audio batteries require maintenance?
A: It depends on the type of battery. Sealed batteries usually don’t require much maintenance but lead-acid batteries need to be filled with water regularly.
