The Odyssey 34-PC1500T is one of the strongest dual-purpose batteries available. With true cranking and deep cycling, these features make for an appealing battery choice. In addition, the plates for this battery are manufactured from pure lead for better performance and durability.

Fast recharging…

Odyssey lays claim to having the fastest recharge efficiency of any sealed battery on the market. I would have to agree with that after trying for it for myself. A complete recharge after being completely discharged can be achieved in only four to six hours.

With this efficiency, it puts less stress on the vehicle’s alternator too. Less stress means less wear and tear, giving your vehicle’s components a longer lifespan. As a dedicated battery for a car stereo, it should keep it running for many years to come.

Spill proof…

Because of the sealed, spill-proof design of the battery, you can place it anywhere you like in the car. As there is no risk of corrosive chemicals leaking, there are no issues with installing the battery in your trunk.

3 XS Power D3400 XS Series – Best Competition Grade Car Audio Battery

XS Power is a very popular battery for use with not only cars but for car audio systems too. The D3400 is an AGM (Absorbent Glass Mat) sealed lead acid battery. With its high power and flexible mounting options, no wonder so many people choose this battery.

What makes these batteries for car audio purposes great, in particular, is the use of the highest chemistry density known in AGM batteries. This has resulted in car audio competition records being smashed with the use of these batteries.

Mount it anywhere…

Thanks to the sealed spill-proof design, the XS can be mounted almost anywhere. It can be mounted in almost any position, too, no matter if horizontal or vertical. It is not recommended to mount the battery upside down, though.

XS Power’s clever design makes this battery resistant to vibration too. That is particularly handy if you plan on powering some large subs and delivering earth-shaking bass. You can be sure that your battery is up for the challenge.

Cranks out huge amps…

This battery pumps out 1000 crank amps with a maximum output of 3300 amps. This makes it more than suitable for multiple amplifier and speaker setups. I would even recommend doubling up with one for your car, and one for your stereo in a dual battery arrangement.

Covered in a reinforced hard ABS plastic case, this 12-volt deep cycle battery is not only a powerhouse; it is tough and durable too. If you are getting serious about your car’s audio system, you need a serious battery, and this might just be it.

If you’re looking for a high-quality battery with all the bells and whistles, this would be a great choice. For better conductivity, it features a calcium lead positive grid. With a vent cap designed to prevent acid leakage, you can be sure of a safe experience.

Charge receptive…

Being incredibly charge receptive combined with the high cycle ability makes for the perfect performance as an audio power supply. As with most of these batteries, it is heavy at 45.5lbs (20.6kgs) but is just a little lighter than most in this category.

Through the use of oxygen recombination, water loss is greatly reduced, resulting in maintenance-free performance. No matter what the weather conditions, this battery is ready to power up your stereo, no matter if it is freezing cold or scorching hot.

Advanced acid circulation…

By using a robust envelope separator, it increases the circulation of acid within the battery. This very effectively increases the cooling capabilities of the battery. No matter how hot the environment, the ACDelco is ready to perform.

In an effort to boost performance and the life of the battery, a high-density negative paste has been used. In addition, enhanced life alloy and silver calcium stamped alloy extends the battery life even further.

Best Car Audio Battery Buying Guide

Best Car Audio Battery Buying Guide

As you can see, there are many different varieties of batteries available for use with a car audio system. If you are planning on upgrading or have already upgraded your car’s stereo, you should certainly not forget about the battery.

If you have already upgraded your stereo but haven’t done a battery upgrade, you may have noticed your headlights dimming. This is due to the extra power required for the stereo putting extra strain on your power supply.

Upgrade to premium

There are two main options when upgrading the battery for your audio system. The first is simply replacing your car’s current battery with a more powerful premium battery. While this method can be effective, it is less desirable.

It will still provide better performance and put less stress on other components of your car, like the alternator. If this is the direction you need to go, I would recommend either the Odyssey or the XR Power battery due to their high crank power.

Secondary battery

The second and most effective option is installing a secondary battery as a dedicated power source for your stereo. Especially if you intend on installing some big subwoofers and powerful amplifiers in your audio system.

Dual battery isolator

If this is the way you would like to go, then you should consider a dual battery isolator. This will extend both batteries’ lives, plus allow for efficient charging by the car’s alternator. Any of these batteries will be up to the task with this arrangement.

If you are still finding it difficult to make that final decision, then check out the last section. I will reveal what I think is the best audio battery for cars and why. But first…
