Having a good sound system installed in your car has the power to turn even something as dull as the daily drive to the office into a fun and immersive listening experience that will get you to sing your heart out.
But here’s the thing:
The moment you install an aftermarket sound system in your car, you’re putting tremendous amounts of strain on your car’s battery.
So, if you want your sound system to play at its peak efficiency – without it affecting the rest of your car – maybe it’s time to consider getting the best car audio battery!
The 9 Best Car Audio Batteries in 2021
1. Optima Batteries 8014-045 D34/78 YellowTop Dual Purpose Battery
When it comes to the best car audio system batteries and car battery manufacturers in general, no one deserves more respect than Optima – a name that’s been in the automotive industry for 40 years now.
Whether you need something that can meet the power demands of your accessory-loaded vehicle or a replacement battery, the YellowTop is the way to go.
There are but a few genuine dual-purpose car batteries out there – and the Optima YellowTop is one of them!
With 750 amps of cranking power and exceptional cycling capabilities, this is the battery that will provide unmatched deep-cycle and cranking performance whenever you need it.
I’d pick this spiral winding continuous lead plates over the standard flat-plate design any day because it allows for unmatched efficiency. Plus, it’s designed to be spill-proof and highly resistant to vibrations, which makes it that much more immune to the common causes of car battery failure.
It weighs 43.5 pounds, so it’s bulky – but considering the high performance, long battery life, and excellent build quality, I’m willing to let it slide.
- Dual-purpose car battery

- It weighs 43.5 pounds
|The dual-purpose design and resistance to the typical causes of battery failure prove that Optima still reigns as the best car audio battery. If you drive an accessory-loaded car or have a power-hungry sound system, this battery is the way to go!|
2. DieHard 38217 Group 49 Lead_Acid_Battery
If you care more about the durability and sturdiness of your car audio battery than its ability to push out high levels of power, the DieHard 38217 could be a good battery for car audio for you. Seriously, if you want a heavy-duty, maintenance-free battery, look no further.
Everything about the DieHard 38217’s design revolves around making it as durable as possible – inside and out. I appreciate all that effort that went into the battery’s structural integrity.
The heat-sealed, tamper-resistant, spill-proof construction, complete with an enhanced suspension system for the internal components, amounts to improved battery life and, more importantly, vibration-resistance that’s up to 20 times higher compared to a regular one.
And if that’s somehow not enough to impress you, the fact that it also brings an 850-amp CCA rating to the table probably will.
However, with all the focus being on making it as sturdy as possible and adding tons of safety features, DieHard ended up with a 60-pound battery.
Sure, the extended battery life is worth it, but you may find it hard to fit in your car.
- Unmatched durability and sturdiness
- Heat-sealed and tamper-resistant
- Maintenance-free and spill-proof
- An 850-amp CCA rating
- The battery weighs a staggering 60 pounds
|DieHard makes some insanely durable and sturdy car audio batteries – and the DieHard 38217 is no exception. If cutting-edge protection and vibration-resistance matter more to you than the moderately high output power, this one is perfect for the job!|
3. Kinetik HC600 Black Lead_Acid_Battery
Now, if you’re not planning a massive sound system upgrade, something like this Kinetik HC600 AGM car audio battery may be right up your alley.
After putting it to the test – and factoring in the low price tag – it’s clear that this is a reliable, affordable pick that still packs enough power for car audio use and boasts a few high-end features. Better yet, it could work as a budget replacement for your car’s standard battery in a pinch, too.
So, don’t assume that, just because it’s cheap, it won’t perform well. Tightly-packed cells ensure higher voltage under load, and the battery is powerful enough to run moderately-sized, 600-watt systems.
I appreciate the overall design, complete with AGM technology and the sealed-off, spill-proof construction.
It’s nice to know that leaks aren’t something to worry about, regardless of where or how you decide to mount it.
Overall, the Kinetik HC600 is a good option – and a cheap and lightweight one at that. But, it provides the least amount of power, and that right there could be a deal-breaker, depending on your needs.
- Best suited for modest, 600-watt systems
- Designed with AGM technology
- Sealed-off, spill-proof, resistant to heat and vibrations
- Cheap and lightweight
- Underpowered compared to others
|The Kinetik HC600 is a cheap and lightweight solution for upgrading any 600-watt sound system on a budget. For a modestly-sized system, this could very well be the best cheap car audio battery out there!|
4. XS Power D3400 XS Series 12V 3,300 Amp AGM High Output Battery
Renowned as one of the best long-lasting, high-output car audio batteries, the XS Power D3400 is an overall premium-quality product.
But with the output power and the price tag being as high as they are, this one can quickly fry your low-quality sound system – and your budget.
Seriously, this thing packs so much power that it can replace your regular car battery without breaking a sweat. It’s perfect for the role of a second battery for car audio systems between 2500 and 3500 watts, though.
We’re talking about a 12-Volt deep cycle battery car audio here. You’re looking at an upwards of 3300 amps of power, so it’s by no means a minor system upgrade.
And the best part is that the design is every bit as impressive as the actual power. When you go with an AGM, closed-cell, vibration-resistant, leak-proof design, you can rest assured that spills and maintenance won’t be a problem.
The weight is a much more significant concern for me than the price tag; at 48 pounds, this thing is a beast.
- AGM technology for ultra-low resistance
- Closed-cell, vibration- and leak-proof construction
- Maximum output of 3300 amps
- Weighs 48 pounds
|If you have big plans for your car’s audio system, this high-performance XS Power D3400 battery with a 3300-amp maximum output and a closed-cell, leak-proof, vibration-resistant design is the way to go!|
5. Odyssey 34-PC1500T Automotive and LTV Battery
I came across this battery that packs pure virgin lead plates, and it hit me – the more plates packed inside, the larger the surface area. Can you see where I’m going with this?
The larger the plate surface area, the higher the power – and with its cold cranking amp rating clocking in at 850 amps, the Odyssey 34-PC1500T lives up to those expectations.
It’s one of the best in its class:
It boasts a lot of the same features that you’ve seen so far, but with the added advantage of a longer cycle life compared to an average deep-cycle battery.
My favorite thing about the Odyssey 34-PC1500T is its high recharge efficiency compared to other sealed lead batteries for car audio. It hits the 100-percent mark in four to six hours of charging!
Plus, considering its non-spill design and the resistance to extreme temperatures, as well as mechanical vibrations and high-impact shocks, you can mount it wherever you want.
The extra lead plates are to blame for the weight of 49.5 pounds, but even if I let that slide, the not-so-affordable price tag is still an issue.
- Utilizes pure virgin lead plates
- Non-spill, vibration-resistant design for versatile mounting
- High recharge efficiency and longer life cycle
- Relatively pricey
- Weighs over 49 pounds
|Rapid recovery system, high recharge efficiency, longer cycle life, and a spill-proof container – these are but a few reasons to get the Odyssey 34-PC1500T, despite its high price.|
6. Stinger SPV44 660-Amp Power Series Dry Cell Battery
Stinger likes to brag about being the first brand to introduce a dry cell battery for car audio, and even though I wouldn’t necessarily say that the SPV44 is Stinger at its most powerful, there’s no denying that it’s a pretty solid choice.
If you want dry cell performance on a somewhat limited budget, this battery – a member of the Stinger Power Series – may be the way to go.
In terms of “versatility,” the battery was designed with two possible applications in mind. You can use it as a standard battery replacement or as an additional source of power for your high-performance audio system.
Either way, its ability to power a 1320-watt system won’t leave you feeling underwhelmed.
Also, the actual construction is impressive and, more importantly, safe. It relies on a sealed AGM design and leak-proof construction to prevent any hazardous leaks. And, it has removable brass battery posts to give you more freedom and flexibility when it comes to installation.
It’s not the best fit for high-performance systems – but stick around for another Stinger battery that is!
- Sealed AGM design with leak-proof construction
- Removable brass posts for flexible installation
- Lasts for over 300 full-discharge cycles
- Doesn’t require a capacitor
- Not suitable for high-performance systems
|It may not be able to drive a high-performance system, but the Stinger SPV44 is far from underpowered. If you need moderate output levels in a reliable package, this could be it.|
7. Kinetik HC1200-BLU Black Lead_Acid_Battery
My only gripe with the Kinetik HC600 was that its power was comparatively low, limiting its applications to 600-watt systems. So, I wanted to include another one of their products in this list, and show you what Kinetik has to offer in the high-performance range.
Enter Kinetik HC1200-BLU, a high-performance car audio battery that comes with the same reliable construction and affordable price tag – but this time around has enough power to support high-end sound systems with up to 1200 watts.
One thing I appreciate about this battery is that it’s designed with high performance in mind, starting with the ultra-low ESR rating that makes it incredibly efficient.
The sealed AGM design with no external vents is another welcome design feature, as it makes the battery a whole lot safer – hazardous leaks are not a concern. Plus, it’s insulated against vigorous vibrations and heat, which gives you an added peace of mind, especially if you drive an off-road vehicle.
Considering everything it brings to the table – and how budget-friendly and compact it is – it’s hard to find a thing wrong with it.
- Works with 1200-watt systems
- Sealed AMG design
- Leak-proof and resistant to heat and vibrations
- Ultra-low ESR for improved efficiency
- Compact and affordable
- None that I could find
|The Kinetik HC1200-BLU is engineered with high-performance in mind. From the sealed, leak-proof AGM design to the ultra-low ESR ratings, everything about this small but mighty battery screams “high performance.”|
8. Gravity Audio 1000A Car Battery
When it comes to the best car battery, looks shouldn’t matter – or at least not as much as the actual capabilities and construction quality. I mean, would you rather have top-notch performance or a good-looking battery that doesn’t do much for your audio system?
Could you have both good looks and a decent enough performance with this Gravity Audio 1000A car battery, though?
It’s pretty evident why so many people who appreciate the appearance as much as they do output go with the Gravity Audio battery. The black chrome housing and the chrome-plated battery posts look stunning.
It’s fitted with a digital display that shows the battery’s voltage, as well as blue LEDs throughout the top panel, which all contribute to the undeniably good looks.
Overall, it’s decent enough for the money – it’s not as good as the XS Power or Kinetik, but it’ll work for a low-end to moderate upgrade.
It’s cool-looking, I’ll give it that much, but the overall build quality – especially the battery posts – and performance failed to impress me.
- Cool design with LED lights on the top panel
- A digital display shows the voltage
- Black chrome housing with chrome-plated battery posts
- Cheaply-made battery posts that break easily
|If you want a good-looking battery with LED lights, a digital display, and all those bells and whistles, the Gravity Audio 1000A is the battery for you. If you value performance and build quality, though, look elsewhere.|
9. Stinger SPV69C 1100 Amp Power Series Dry Cell Battery
I did promise to show you another one of Stinger’s batteries for audio, didn’t I?
So, before I wrap things up, allow me to introduce you to the Stinger SPV69C – a mid-range car audio battery that’s a step above the baseline performance-wise and has a price tag to match.
If you liked the previous Stinger model, but need a battery that can run moderate to high-performance sound systems, this could work well for you.
Again, what I like about this Stinger battery is its overall reliability – and I’m not talking solely about its performance, either. The way it’s designed is exceptional, as well.
It utilizes AGM technology and is completely sealed to minimize the chance of hazardous leaks. As such, it can be mounted virtually anywhere and requires zero maintenance, which is a plus in my book.
The Stinger SPV69C is said to produce up to 2000 watts, although, again, the manufacturer’s recommendations say that you should stick to powering 1320-watt systems with this one. I’m not sure what’s up with that, but it is what it is.
- 12V dry-cell battery that produces up to 2000 watts
- Sealed AGM design is maintenance-free and leak-proof
- Handles over 300 full-discharge cycles
- Used as a replacement or an auxiliary battery
- Recommended for 1320-watt systems max
|Designed for a system that’s a step above the baseline – but not precisely high-end – this Stinger SPV69C battery is a mid-range option worth considering.|
What Is The Best Car Audio Battery?
You got this far, so it’s safe to assume that you’ve read the reviews and already have a pretty good idea of which features and specs matter the most when it comes to car audio batteries. Size, price, maintenance, battery life, heat- and vibration-resistance, and ease of installation – these are all things that need to be considered.
But most importantly, you need a car audio battery that can push out as much power as your sound system requires. That is the one factor that is non-negotiable here.
Even if everything else seems to be in order, when the battery’s cold-cranking amps and the watts that it’s capable of producing don’t sync up with the system’s power requirements, you’ve got nothing. Worst-case scenario, you could damage the entire system.
In short, the best car battery for your audio system is the one that, well, works with your sound system.
And based on all the factors I explained above and my hands-on experience with it, I’d say that the title of the best battery for car audio system should go to the Optima Batteries 8014-045.
How to choose the Best Car Audio Battery
Choosing a good car audio battery may seem like a piece of cake, but you should truly take your time picking it out before you’re sure that’s the one for you. Nobody wants to spend a huge amount of money on a car battery to find out it isn’t what you asked for.
So, there are a few things to keep in mind when you’re buying a battery, to make sure it’s the best car audio battery for you! Here are those things!
Size of the battery
Before you start looking into anything else, you should check out the size of the battery you want to buy. Compare it to the battery you already have, to make sure it’s not too large.
The battery you want has to fit your car model, and it needs to be completely compatible. Information on that is usually available online, in the product description or the manufacturer specs. If you have additional questions, you can always contact the manufacturer via customer service or email for more info.
Find the place where you want to install the battery and measure it. Then compare those numbers to the numbers online. Be precise, because receiving a battery that doesn’t do it only gives you the trouble of having to send it back and wait for the other one to arrive.
The reserve capacity of a battery is a sign of how much power your battery has. In other words, how much time you have until the battery needs a full charge.
At the very least, you should look for a battery that has at least a few hours – especially if you use the car audio without the engine running often. If you need to power more accessories than just audio, consider investing in a battery with a reserve over a few hours.
Many batteries mentioned in this article are described as maintenance-free, even hassle-free, as they are designed to make your life easier.
A maintenance-free battery means that you don’t need to add liquid in it for the battery to continue working. Most of these modern-day batteries are sealed, so you don’t need to open them to work on them in any way whatsoever.
Handle or loop
This factor may seem trivial, but listen up first. If the battery has a plastic handle or a loop, that makes the battery super easy to carry and move around. If you never lifted a car battery before, you may not know how heavy they can be!
A battery, even a smaller one, can be quite heavy – making it quite difficult to move around if it doesn’t have a handle. The handle can also help you put the battery into the compartment under the hood. The place is cramped as is, so it’s always good to have it.
Easy to install
When you want to install your new battery, you may find how limited the space under the hood is. It can happen with large cars, but this is usually the problem of small hatchbacks.
If that’s the case with your car,look for a sealed, spill-proof battery which can be mounted in a variety of different places. If you decide to mount the battery into an unusual place, the battery fluid can leak out. That’s why you should definitely opt for a spill-proof model, so you don’t have to worry about leaks and spills.
If you’re sticking to a budget, have a moderately-sized system installed – or simply want to go with a familiar name – the Optima Batteries 8014-045 is the best car audio battery for you.
If you’re upgrading to a high-end, power-hungry sound system, though, then the XS Power D3400 is a much better choice. Yes, it costs way more than any other option, but the premium-quality construction and overall reliability are well worth it.
Ultimately, though, it’s about finding the right match for your setup – and in that sense, any of these batteries could be a good fit.
