Top Eclipse Car Battery Questions

  • Why doesn’t my Eclipse battery stay charged? A car battery that needs to be jump-started every time is as good as dead. The battery might be old. Or, you may have a habit of leaving your car doors open and the dome lights on during the night. Stop by for a complimentary battery check at your favorite Firestone Complete Auto Care to learn more about the state of your battery.

  • What’s the cost of DieHard batteries for Mitsubishi Eclipses? You can find affordable Eclipse batteries by using one of our car battery coupons, when available. Plus, every DieHard battery comes with extra coverage thanks to DieHard Assurance and a free replacement warranty.
  • What is the average lifespan of a car battery? A car battery normally lasts three to five years, but this number can vary based on battery type, your driving habits, and battery maintenance.
  • Why is there white, crusty buildup on my Eclipse’s battery post? The white, crusty stuff that can accumulate around Eclipse car battery terminals is called corrosion. It is caused by a chemical reaction between the battery acid and the air, which creates a white, powdery substance that can build up on the terminals over time. Corrosion can interfere with the flow of electricity between the battery post and the car's electrical system, sometimes leading to poor electrical performance, difficulty starting, and even premature battery failure.
  • How do I remove corrosion from my Eclipse car battery? You can help prevent or get rid of corrosion by regularly inspecting and cleaning your battery terminals. Before cleaning your battery, see your Eclipse owner's manual to learn how to disconnect the battery cables. After disconnecting the cables, use a mixture of water and baking soda, a wire brush, and a rag to carefully clean the terminals.
