Corrosion on Car Battery

Car Battery Replacement

A battery is what allows the engine to start after you turn the key or push the ignition button. Not only that, but it’s a power source for the lights and other electronics inside your automobile.

Over time, the battery may form corrosion, which can prevent it from doing its job. If that happens, then you may not be able to start your car in Albuquerque, Rio Rancho, or South Valley.

That’s why it’s crucial to clean the battery once corrosion forms. Below, we’ll tell you exactly how you get corrosion on a car battery and how to remove it. Read through our detailed guide, and feel free to contact us at Land Rover Albuquerque if you have any questions.

What Causes Corrosion on a Car Battery?

Corrosion on Car BatteryCorrosion can form on the terminals when hydrogen gas is released from the acid in the battery. Once that hydrogen mixes with other molecules in the atmosphere, corrosion will start to appear.

However, there are other reasons why you might see corrosion. These include:

  • The terminal and cable end are made up of different types of metal.
  • The battery gets overcharged, which causes it to heat up and expand, pushing electrolytes out of the vents.
  • The battery gets to be too old (over four years).

If you see a crusty, fuzzy-looking substance on the terminals and cable ends, then you know corrosion has formed. When this happens, it can prevent power from flowing from the battery through the cables, which means your vehicle could become inoperable.

That’s why you’ll need to clean the car battery at the first sighting of corrosion, which we’ll go over how to do below.

  5. If everything looks good, then you can create a cleaning solution using one tablespoon of baking soda and one cup of hot water.
  6. Dip the toothbrush into the solution and scrub the top of the battery to remove corrosion buildup.
  7. Repeat Step 6 for the battery clamps and posts.
  8. Rinse the battery and cables with cool water, then dry them with a clean cloth.
