  • Why won’t my 300TD battery hold a charge? A car battery that needs to be jump-started every time is as good as dead. The battery may be too old. Or, you’ve been leaving the doors slightly open and the cabin light at night. Stop by for a complimentary battery check at your nearest Firestone Complete Auto Care to learn more about the state of your battery.

  • How often should I replace my car battery? Car battery lifespan varies depending on a few factors, including driving conditions, accessories,  how well it’s maintained, and the type of battery. On average, a car battery lasts about three to five years.
  • Why is there white, flaky stuff around my 300TD’s battery post? The white, crusty stuff that can accumulate around 300TD 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 clean corrosion off my 300TD vehicle 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 300TD owner’s manual for instructions on how to do so.
