  • Why won’t my Mountaineer battery hold a charge? 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 free battery test at your favorite Firestone Complete Auto Care to learn more about the state of your battery.
  • What do you do with my dead Mountaineer battery? We recycle it, taking care of both your car and the Earth.
  • What’s the cost of DieHard batteries for Mercury Mountaineers? Mercury Mountaineer 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 long is a car battery good for? A car battery normally lasts three to five years, but this number can vary based on battery type, your driving habits, and battery maintenance.
  • What is the white, crusty substance accumulating on my Mountaineer’s battery post? If you notice white, crusty stuff around the battery terminals of your Mountaineer, 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 Mountaineer’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.
  • How do I clean a corroded Mountaineer 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.
