What to Look for the Dependable Car Audio Battery

High Performance

One of the most important factors that you need to focus on when looking for a reliable car audio battery is its performance. Your chosen battery should consistently perform at the optimum level.

If you want your car audio system to perform well without affecting other parts of your car, choose a car battery with high rating performance. If you choose the wrong type of battery, there is a higher chance that it will drain easily, especially with an upgraded stereo or other car accessories.


Choose a battery that can withstand ​extreme weather conditions. High temperature can increase corrosion of the plates, and vaporize the electrolyte.

Select the battery with a higher CCA or Cold Cranking Amps. It measures the capability of the battery to start the engine during extreme cold weather conditions.

Types of Battery

Absorbed Glass Matte or AGM

AGM or Absorbed Glass Matte battery is designed to withstand repeated draining and recharging cycles better,compared to standard batteries.

The biggest advantage of the AGM battery is that the acid is absorbed by the fiberglass mat, which makes them spill-proof. This type of battery is maintenance free, with exceptional reliability and is lighter ​compared to flooded lead acid batteries.

Deep Cycle Batteries

This type of battery offers continuous power for longer. These batteries are made to be discharged regularly, using most of its capacity. This type of battery is not intended as a starter battery because it does not offer the same surge that a starter battery can offer.

Choosing the Right Battery for your Sound System

Matching the battery on your car sound system is easy. Just add the total wattage of your equipment and then look for batteries that can match the cranking amps.

  • Cranking amps are the electric current the battery is capable of. The higher the number, the more powerful it will be. Match this to the total RMS wattage of your system.
  • Ampere hour is the capacity of the battery and is measured by multiplying the current flow in amps by the time it discharges.
  • Amperage measures the rate at which the electric charge passes into the battery.
