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