Tips

  • It’s best to choose a maintenance-free battery to make your life easier. They are normally sealed and don’t require the user to add any liquid for it to work properly.
  • Always ensure that your battery has enough reserve capacity to run for at least a couple of hours. This is particularly important if you intend to use your car audio without the engine running.
  • Redtop batteries work well with most vehicles that don’t have high electrical loads. Yellowtop batteries are better for cars with many electrical features, including amplifiers and speakers.
  • Since batteries are heavy, having a handle or loop can make it much easier to lift and install.

FAQs

Q: Why does car audio need a dedicated battery? 

A: Regular batteries are designed to start the engine and other basic functions. Advanced car audio systems draw significantly more power and require a battery that will allow for the best quality sound without harming a vehicle’s electrical components.

Q: Why should the battery be vibration resistant?

A: Sophisticated car sound systems normally have a strong bass that can cause the car to vibrate. Constant vibrations can cause damage to regular batteries that aren’t built to take it

Q: Do car audio batteries have a warranty?

A: The lifespan of a car battery can vary according to the quality, or even how it has been used. Good quality batteries have a warranty of around three years to safeguard the buyer from any defects.
