Stop in for a free battery check at your local Firestone Complete Auto Care and learn more about your battery's charge.

  • What is the average lifespan of a car battery? You can usually get three to five years out of your car battery. However, battery type, how well you maintain your battery, and your driving habits can all affect your battery’s lifespan.
  • Why is there white, flaky stuff around my Trailblazer EXT’s battery post? If you notice white, crusty stuff around the battery terminals of your Trailblazer EXT, it's likely corrosion. A chemical reaction between battery acid and the air can create a white, powdery substance that builds up over time on the terminals. This buildup can interfere with the electrical connection between the battery and your Trailblazer EXT’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.
  • How do I clean a corroded Trailblazer EXT battery terminal? To help extend the life of your battery, you should routinely inspect and clean the terminals using a baking soda and water mix, wire brush, and rag. Be sure to disconnect the battery cables before cleaning and check your Trailblazer EXT owner’s manual for instructions on how to do so.
