  • How often should I replace my car battery? 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, flaky stuff around my Roadmaster’s battery post? The white, crusty stuff that can accumulate around Roadmaster 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 a corroded Roadmaster battery terminal? You can help prevent or get rid of corrosion by regularly inspecting and cleaning your battery terminals. Before cleaning your battery, see your Roadmaster owner's manual to learn how to disconnect the battery cables. After disconnecting the cables, use a mixture of water and baking soda, a wire brush, and a rag to carefully clean the terminals.
