12 best battery for car audio system
A car audio system can place significant demands on a vehicle's battery. Here's what you need to know about batteries for car audio systems:
Battery Capacity: The capacity of a car's battery is typically measured in ampere-hours (Ah) and determines how long the battery can power the car's electrical components, including the audio system, without being recharged. A higher Ah rating usually means longer-lasting power.
Deep Cycle vs. Starting Batteries: Car batteries fall into two main categories: starting batteries and deep cycle batteries. Starting batteries are designed to deliver a short burst of high current to start the engine, while deep cycle batteries are built to provide a steady, low-level current over a longer period. For car audio systems, deep cycle batteries are generally preferred because they can handle prolonged periods of power drain without being damaged.
Battery Size and Fit: The physical size of the battery is crucial, as it must fit in your vehicle's battery compartment.Make sure to check the dimensions of your existing battery and choose a replacement that fits properly.
Reserve Capacity: Reserve capacity (RC) is another important metric to consider. It indicates how long a battery can deliver a specified amount of current (usually 25 amps) before dropping below a minimum voltage. A higher RC is desirable for car audio systems.
Cranking Amps (CA) and Cold Cranking Amps (CCA): These ratings are crucial if you're using a battery that also needs to start your vehicle. CA and CCA represent the battery's ability to deliver a burst of power in cold conditions. Ensure the battery you choose meets the requirements for your vehicle's starting needs.
Dual Batteries: In some high-performance car audio setups, enthusiasts use dual battery setups. One battery is dedicated to starting the vehicle, while the other powers the audio system. This helps prevent audio system power drain from affecting the vehicle's ability to start.
Battery Isolator or Relay: If you opt for a dual battery setup, you'll need a battery isolator or relay to ensure that one battery doesn't drain the other when the engine is off. These devices manage the power distribution between the batteries.
Maintenance: Regular maintenance is essential to ensure your battery's longevity and optimal performance. Keep the terminals clean and free of corrosion, and periodically check the battery's fluid levels if it's a conventional lead-acid battery.
AGM Batteries: Absorbent Glass Mat (AGM) batteries are a popular choice for car audio systems. They are spill-proof, maintenance-free, and can handle deep discharges without damage. AGM batteries are also known for their superior vibration resistance.
Lithium-Ion Batteries: Some enthusiasts opt for lithium-ion batteries due to their lightweight and high energy density. However, they are more expensive than traditional lead-acid or AGM batteries.
In summary, selecting the right battery for your car audio system involves considering factors such as capacity, type (deep cycle vs. starting), size, and additional features like dual battery setups and battery isolators. Ensure that the battery you choose meets the specific power requirements of your audio system while also considering your vehicle's starting needs. Regular maintenance is crucial for optimal battery performance.

User questions & answers
| Question: | If this replaced stock battery would it help power 1500 watts rms with 85 amp stock alternator and the big three |
| Answer: | I know this is a late response to the OP, but i figure it can help future potential buyers... I am using this battery as a starting battery, but I also have abank of 3 in the hatch, however, while I was planning out the big build, I used one of these as a stand alone starting battery with a Crescendo Audio BC2000D at 1 ohm and it was "ok". This was with the big 3 all at 1/0, Knu OFC and a stock alternator, 110 amp. Lights still dimmed, but no where near what they were with the stock pos lead battery. In my case, according to XS, this was the only battery that would fit my vehicle up front. I took some measurements and, well, without modifying anbything in my engine bay, they were right, so I went with it. Yes, according to XS these batteries are capable of handling 1500-2000 watts RMS of power, however remember that youi have the rest of your vehicle running, too. Headlights, heat, AC, wipers, etc, all these things draw power too, and let's not forget the car's computer system itself which is running constantly when the car is running. You need to take this into account if you are considering using this battery as a stand alone. As another poster replied, this does wonders as an additional battery, however you don't want to run a lead acid and AGM together in parallel without an isolator. Reason being is that these AGM batteries have a resting voltage of 12.8 to 13 volts. A typical lead acid has a resting voltage of 12.3 to 12.5 volts. When batteries are paralleled together, at rest, they will try to find "even" voltage between them. That is, if you had a battery at 14 volts parallel connected to one at 12 volts (I would NEVER recommend this, extremely dangerous, just using it for easy numbers), the resting voltage would be 13 volts, The problem with this is, the 12 volt battery would constantly be drawing voltage from the 14 volt battery in order to achieve this balance. With a lead acid and AGM you have the same issue, the lead acid, being at 12.5, would be draining constantly (when the car is off) from the 12.8 volt AGM battery. What's the big deal, you ask? Nothing if you like buying a new AGM every year. This will shorten the lifespan of the AGM considerably, it is not healthy for an AGM battery to have this draw on it when at rest. A simple solenoid isolator cane easily be added to this equation so when the car is off, the batteries don't see each other. Now, I would recommend going with different models of XS for a battery bank, due to the way these posts sit all recessed and what not, but I made it work just fine with my own custom bus bars. |
| Question: | Will this battery power a Rockford Fosgate T1500 around 1800 watts rms |
| Answer: | You have to do more research about the big 3. The battery alone wont be able to handle that kind of power, no battery will. |
| Question: | Can I use the "XS Power 551 I-Bar Side and Top Terminal Adapter" to make this a side-post battery |
| Answer: | yes |
| Question: | You have to buy the $200 battery charger before you can use it, right |
| Answer: | Nope, I bought a $60 CTEK charger, actually, this one here: https://www.amazon.com/gp/product/B006G14FK8/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1 I am using a bank of these and it topped off every one of them to 13.8 volts without a hitch. |

User questions & answers
| Question: | I have a 2020 wrangler with a 240 amp alternator. is this rated to work with my alternator? i will be adding a second battery for low-draw accessories |
| Answer: | It should work with anything 12V. The wires are to connect the two batteries together with the isolator in the middle of the positive leads. |
| Question: | can this be use to charge a lithium batteries on the second battery |
| Answer: | No it will only Isolate 1 battery at a time. |
| Question: | Will the alternator charge battery 2 with this while car is running |
| Answer: | It varies depending upon amperage flow and timing. This is all part of True Amalgamated's PEP programming and is not disclosed by the manufacturer. If used in a UTV/ATV it would provide the service advertised. It will activate in the mid 13 volt level and deactivate in the upper 12 volt level and varies as explained. |
| Question: | What gauge is the supplied wires |
| Answer: | I also trickle charge. I have the Battery Tender Jr. harness connected to the pos and neg of the main battery. This will send the charge through the one way isolator and charge the second battery. The blue light in the isolator will come on when the signal is sent through. If you put the harness on the second battery, the charge does not go through the other way, back to the main battery (from what I have been told). Hope this helps. |

| Question: | i have a 6000watts sistem in my car will this be good |
| Answer: | Thank you for your inquiry. DieHard 2871688 Platinum Portable Power 1150 is not a battery maintainer. It is a portable power pack used for jump starting or a portable short term power source. It must be plugged in after use and once a month to maintain the internal battery. Do not plug in while in use. |
| Question: | Will i need to upgrade my alternator |
| Answer: | From a technical standpoint, it should work, but I never thought to try that technique. I do know that I am glad that I purchased one of these units. I took a 5 month road trip last year and it came in handy a number of times from jumping off a low car battery to charging my laptop or cellphone. |
| Question: | What do they mean 20 hrs |
| Answer: | It does not come with an air compressor but it easily powers a stand alone 12v dc small air compressor. I've used it many times for that. |
| Question: | I know this is a 12V battery, but could i get away with chsrging it to higher voltage without damaging the battery |
| Answer: | It is made in China. However, the quality seems very good. I have been using it almost every weekend since the beginning of September and so far it has been great. A couple of the guys I hunt with are ordering one as well. Using the converter only, we charge all of our phones and other items and it last the whole weekend, only draining about half the charge. Honestly, it rarely gets turned off. |
