In terms of battery maintenance, what is the recommended action if the battery terminals are corroded?

  1. Replace the battery

  2. Clean the terminals

  3. Apply grease

  4. Do nothing, it’s normal

The correct answer is: Clean the terminals

When battery terminals are corroded, cleaning the terminals is the recommended action because corrosion can impede the flow of electricity and affect the overall performance of the battery and vehicle. Battery terminal corrosion typically appears as a white, ashy substance that can be the result of chemical reactions between the battery acid and the metal of the terminals. By cleaning the terminals, you can remove this buildup and restore a good connection between the battery and the vehicle's electrical system. This helps ensure that the battery can charge and discharge effectively, which is essential for starting the engine and powering electrical components. In addition to maintaining a clean connection, it's also beneficial to regularly check the battery terminals and perform maintenance to prolong the battery's lifespan and enhance vehicle reliability.
