  • Why won’t my Eclipse battery hold a charge? A battery is in its final hour when it will no longer hold a charge. 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 in for a free battery check at your favorite Firestone Complete Auto Care to learn more about the state of your battery.
  • What do you do with my dead Eclipse battery? We recycle it! Nearly 100% of all lead-acid batteries are recyclable.
  •  How much do DieHard batteries cost for your Mitsubishi Eclipse? Mitsubishi Eclipse batteries can be affordable, especially when there's an available battery coupon. The best part is every DieHard battery comes with a free replacement warranty and extra coverage with DieHard Assurance.
  • How often should I replace my car battery? The typical 12-volt car battery may last three to five years, depending on the type of battery, the driving conditions, and how well the battery is maintained.
  • What is the white, crusty stuff around my Eclipse’s battery post? A chemical reaction between battery acid and the air can cause a white, crusty buildup to form on the terminals of your Eclipse car battery. This buildup — known as corrosion — can impede the flow of electricity and cause a range of issues, from poor performance to premature battery failure.
  • How do I clean a corroded Eclipse battery terminal? Regularly inspect the terminals and clean them with a mixture of baking soda and water, a wire brush, and a rag. Disconnect the battery cables before cleaning to help avoid the risk of electrical shock. Always reference and follow the instructions in your vehicle owner’s manual prior to disconnecting the battery cables.
