  • Why won't my 318i battery stay charged? A car battery that needs to be jump-started every time is as good as dead. The battery may be too old. Or, you may have been leaving your car doors ajar and the dome lights on during the night. Stop by for a complimentary battery check at your local Firestone Complete Auto Care and get a handle on your car battery’s health.
  • What do you do with my dead 318i battery? We recycle it, taking care of both your car and the Earth.

  • 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 318i’s battery post? If you notice white, crusty stuff around the battery terminals of your 318i, 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 318i’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.
  • How do I remove corrosion from my 318i car battery? 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 318i owner’s manual for instructions on how to do so.
