The surface charge on a car battery is a common issue that can affect its performance and overall lifespan. A surface charge occurs when the battery’s terminals and plates become coated with a layer of corrosion, dirt, and grime, which can prevent the battery from functioning properly. In this blog post, we will explore the importance of removing surface charge from a car battery and provide a step-by-step guide on how to do it safely and effectively.
Why Remove Surface Charge from a Car Battery?
Removing surface charge from a car battery is crucial for several reasons. Firstly, it can improve the battery’s performance by allowing it to hold its charge better and provide a stronger starting current. Secondly, it can extend the battery’s lifespan by preventing corrosion and damage to the terminals and plates. Finally, it can also help to reduce the risk of battery failure, which can leave you stranded on the side of the road.
Causes of Surface Charge on a Car Battery
There are several causes of surface charge on a car battery, including:
- Corrosion: Corrosion can occur when the battery’s terminals and plates come into contact with moisture and oxygen, causing a chemical reaction that forms a layer of corrosion.
- Dirt and grime: Dirt and grime can accumulate on the battery’s terminals and plates, preventing the battery from functioning properly.
- Age: As a car battery ages, its terminals and plates can become worn and corroded, leading to surface charge.
- Incorrect maintenance: Failure to maintain the battery properly, such as not cleaning the terminals and plates regularly, can lead to surface charge.
Signs of Surface Charge on a Car Battery
There are several signs that may indicate surface charge on a car battery, including:
- Slow engine crank: If the engine takes a long time to crank when starting the car, it may be a sign of surface charge.
- Weakened battery performance: If the battery is not holding its charge as well as it should, it may be a sign of surface charge.
- Corrosion on the terminals: If you notice corrosion on the battery’s terminals, it may be a sign of surface charge.
- Difficulty starting the car: If the car is difficult to start, it may be a sign of surface charge.
How to Remove Surface Charge from a Car Battery
Removing surface charge from a car battery is a relatively simple process that can be done at home. Here are the steps:
Step 1: Clean the Battery Terminals
To remove surface charge from a car battery, you need to clean the battery terminals and plates. You can use a wire brush and some baking soda and water to clean the terminals. Apply the baking soda and water mixture to the terminals and let it sit for a few minutes. Then, use the wire brush to scrub the terminals and remove any corrosion or dirt.

Step 2: Apply a Corrosion Inhibitor
Once you have cleaned the battery terminals, you need to apply a corrosion inhibitor to prevent corrosion from forming again. You can use a product such as WD-40 or a corrosion inhibitor spray. Spray the product onto the terminals and let it sit for a few minutes. Then, wipe off any excess product with a clean cloth.
Step 3: Check the Battery Cables
Next, you need to check the battery cables to make sure they are clean and free of corrosion. Use a wire brush to clean the cables and remove any corrosion or dirt. Then, apply a corrosion inhibitor to the cables to prevent corrosion from forming again.
Step 4: Test the Battery
Once you have cleaned the battery terminals and cables, you need to test the battery to make sure it is functioning properly. You can use a multimeter to test the battery’s voltage and charge. If the battery is not holding its charge, you may need to replace it.
Precautions to Take When Removing Surface Charge from a Car Battery
When removing surface charge from a car battery, there are several precautions you need to take to ensure your safety and the safety of your car:
- Make sure you are in a well-ventilated area to avoid inhaling any fumes from the cleaning products.
- Wear protective gloves and safety glasses to protect yourself from any chemicals or debris.
- Avoid touching any electrical components or wires while cleaning the battery, as this can cause a short circuit.
- Make sure the car is in park and the parking brake is engaged to prevent the car from moving while you are cleaning the battery.
Conclusion
Removing surface charge from a car battery is a simple and important process that can improve the battery’s performance and extend its lifespan. By following the steps outlined in this blog post, you can safely and effectively remove surface charge from your car battery and keep it running smoothly.
