  • Mount the solenoid in the motor compartment as close to the starting battery (if possible). You can do this by using Velcro and once mounted, run the wire from the solenoid to the frame to secure it.
  • Take your power wire from the positive terminal found on the solenoid and run it to the audio battery. Do not connect it, you will do this in the end.

FAQs on Car Audio Batteries

Here we have some frequently asked questions and answers to them about the car audio batteries.  Let's have a look-

  • What is the approximate lifespan of a car audio system battery?

A standard AGM deep-cycle battery has a lifespan of around six to eight years.

  • A car battery made of what?

The car battery is a lead-acid formulation. In general, it contains 30% sulfuric acid and 70% water base.

  • Does temperature affect a car battery?

Yes, it does. Because the amp-hours it holds reduce when the temperature goes down and increase with warmer weather. The normal rating when standing at room temperature is 77F but when it drops to -22F the AH drops to 50%. The opposite happens when the temperature warms up.

  • What is the difference between the cycle and lifespan of a battery?

The battery cycle is the discharge and recharge rate it takes when used. The life of the battery relates to how deep the cells cycled each time. If a battery discharges to 50% on a daily basis, it will last longer compared to one that is cycled to 80%. For instance, if the battery cycled only 10% it lasts five times longer as one with a 50% cycle.
