6 Best Car Audio Batteries

As we commute for work, we hear people playing different kinds of music, be it in a taxi cab, bus or a personal car. But did you know that for a stereo system to be playing in a car, it requires constant power supply?

Well, every car requires constant power supply. And this is made possible by a second battery installed in your car. This second battery is specifically meant to power up your stereo system. So In this article, we are going to look at the best car audio batteries on the market. And these are the power supply batteries that make it possible for you to be jamming to that Kanye west or Adele song in your car. But first we shall look at how the car audio batteries work and the types so that you can see which one will perfectly fit the sound system of your car.

How car audio battery work.

All cars come with an original battery installed for the audio system. But not all original batteries have the high quality of performance for the stereo system that the car owner requires. So you are advised to install a second battery. And this will power up the stereo system even when the engine is off.

Basically there are two options that you have if your stereo system must run on a high performance.

The first option is to replace the original battery. The replacement battery must be bigger but yet fitting on the space of the original battery. And also it must have a higher capacity than the original battery. This option is more efficient and quickly attainable.

The other option is a little more complicated. It requires putting an additional similar battery that acts as a backup. But you will have an added advantage of additional voltage on reserve. That will be more beneficial to you because it will be fixed right next to the car amplifier.

The capacity that has more reserve is the most preferable when you are looking for high energy performance stereo system. This is one of the two most important ratings of a battery. The other one is the CCA, the cranking amp. This helps maintain high performance in cold and unfriendly environments.

When the car is heavily loaded, the battery releases more amps at a time. And this is what Cranking the engine is all about. It’s all about how much a battery can release amps when both the capacity for reserve and the engine are being cranked overtime. The standard measurement for this is per hour of amps. This should means you should look for a car audio battery that has a lot of capacity for reserve.

The only thing that matters is that the replacement battery easily fits the space of the original battery, and also if it can be easily strapped. But be sure that that the replacement battery has more capacity for reserve. Otherwise, it won’t make any difference with the replacement. So you don’t have to worry about the space in your car. As long as the replacement fits, you are ready to play your stereo.

Adding a second battery to a car for high audio system performance

Additional reserve capacity can actually be attained by simply adding an extra battery. Similar batteries with extra reserve capacity, that has the same age and manufactured by the same company yields the best results. The second batteries must have the same manufacturing date as the first battery. This is important to observe because one battery might drain the other. This will also lead to one of your battery overworking more than the other. If this happens then both batteries will not have a long lifespan.

The best way to start the process is by first learning how to wire a second battery in multiple ways.

If you are setting up new batteries that are alike, then you should begin by setting a second battery on the right side. The right side is where the original battery was. Then you connect the remaining one in parallel position. Positioning the other battery in parallel makes it easier to connect the negatives and positives on both batteries. On a safety note, it’s advisable to install the second battery in a battery box. This is because the second battery is required to be installed under the passenger seat. This protects your passengers from ever getting spilled on by battery fluid or being electrocuted.

Speaking of safety, it’s also important to use heavily insulated battery cables. You should observe that the positive cable should have a fuse designed in-line. This fuse must be installed on both the secondary and the original battery. This will provide additional protection.

You must have a good positioning for strapping the two batteries. Strapping to the chassis is more advisable because of its firm grounding. You must not connect the negative terminals if you going to ground both batteries. On the other hand, if you are not going to ground them, then you are advised to connect both negatives. This will help avoid unforeseen battery problems.

You are advised to fix the new battery close to the amplifier. This will help connect the new battery with amplifier directly which will yield the best results. The trunk is the best part of the car to install the new battery with the amplifier. But don’t forget to use an inline fuse type of an amplifier for safety. This should be installed between the amp and the replacement battery.

Types of car audio batteries

Each car has a different sound system that requires a specific amount of power to be supplied. Some second batteries may not work for some cars because of their specifications in their making. So you are advised to know your type of car audio system before you make any car audio battery purchase.

i. Calcium car audio batteries

This type of car audio battery is made up of calcium plates. The calcium plates are not charged at the same time. It is done separately. Scientists have not yet discovered how a calcium car audio battery can be charged at room temperature. The major function of Calcium in this type of a battery to reduce the rate, at which the battery is discharging, Calcium reduces the speed at which the amount of distilled water is lost in the battery.

ii. Deep Cycle car audio batteries

This type of battery in most instances it’s the lead acid type of a battery. This mean that they are equipped with permanent fillers that hold the battery fluids without ever worrying about spilling. The cost of operating this type of battery is very low. This is because they are designed to maintain high performance at a longer period of time without frequent charging. This also prolongs the lifetime of the battery. The deep cycle audio battery is installed with thick plates. The thick plates help the charging capacity of the battery to increase. On the downfall part, the deep cycle discharge at a very faster rate.

iii. Wet Cell car audio batteries

Wet cell car audio batteries don’t require frequent adding of distilled water. This is because they are designed to be are spill-proof. The plates are well covered even though they are placed in the distilled water. This feature makes them one of the best cars audio AGM type of batteries because they are maintenance-free. This reduces the cost of maintenance of the battery.

Iv.The Valve-Regulated Lead-Acid car audio battery (VRLA)

This type of battery is equipped with a limited amount of acid in the separators of the plates. The logic behind this design is to allow oxygen to regenerate in the battery cell. VRLAs are also installed with permanent fillers that provide safety during operation. These features blokes the fluid from ever spilling out. In the case of battery malfunctions, you can easily replace them without ever worrying about the fluids spilling on you.

v. Lithium-Ion car audio battery.

This battery was commercialized by Sony in the 1980s. They don’t affect the memory of the cells besides LFP, and most of them have an energy density between 100W and 265W. The amount of energy this type of battery stores is what makes it the most expensive. This makes mass production to be so limited because not many vehicles use these types of battery. They are popular in the vehicles for the defense and aerospace industry.
