How to Buy the Best Car Audio Battery

How to Buy the Best Car Audio Battery

1. Size and Compatibility

The first thing you should consider is the size of the car audio battery. You will need a place to install it inside your vehicle, so it must be the perfect fit.

On top of this, you must ensure the battery is compatible with the audio system. Check the wattage and ampere rating of the system, then pick a unit that can supply this power.

2. Dedicated or Dual-Purpose Audio Battery

A dedicated car audio battery is solely for supplying your audio system with power. Also called a deep-cycle battery, it discharges slowly, and therefore, you should not use it to start your car.

The advantage of this is that the current is not shared, which means your audio system will get all the power it needs to perform optimally.

However, dual-purpose batteries are ideal for both starting and deep cycle use. They are more versatile, but if you want this type, ensure it is powerful enough to handle both functions.

Ideally, the CCA should be above 600, the charge capacity above 50 Ah, and the reserve capacity over 1 hour. For this, you can check out the Optima 8014-045.

3. CCA and Reserve Capacity

CCA or Cold Cranking Amps is a measure of the number of amps that a battery can deliver in 30 seconds at 0ºF without dropping below 7.2V.

This only applies to starting or dual-purpose batteries, and the higher the rating, the better because such units can crank large engines with ease.

On the other hand, reserve capacity measures the number of minutes that a fully charged battery will discharge 25 amps (at 80ºF) until it drops below 10.5V.

It shows how the unit performs over a long time, which is like the opposite of CCA. The longer the duration, the better, and this shows the battery can run the audio system much longer.

4. Handle or Loop

The handle at the top of your car audio battery is for portability purposes. If it is not there, you will have a hard time carrying the product, especially considering most of them are very heavy.

5. Battery Life

Measured in discharge cycles, more is better, and you should consider a car audio battery that has at least 300 discharge cycles so that you get value for money. In this case, Odyssey's PC680 hits the 400-mark, and we recommend it.

6. Maintenance

For easy use, maintenance-free batteries are the way to go. Look for fully-sealed designs with Absorbent Glass Mats between the cells. These features ensure there are no leaks, and consequently, there will be no need to refill the cells using distilled water once the level goes down.

7. Vibration Resistance

Generally, cars vibrate when moving. A powerful audio system will also cause a lot of shaking. Therefore, you must ensure your preferred battery is vibration resistant to prevent damages when in use.

Conclusion

To sum it up, the Optima 8014-045 is our best overall car audio battery due to its dual-purpose functionality. Additionally, it is very durable and has a unique spiral cell design that gives a high charge capacity.

That said, if you have installed a powerful sound system, it makes more sense to go for the XS Power D3400. It delivers 3300 Amps and has a high 65 Ah charge capacity.

However, if you are short on cash, you should consider the VP-6003. It is very affordable but still delivers a decent 600 watts.
