Step 2: Mix the Baking Soda and Water

Mix 1 tablespoon of baking soda with 1 cup of water to create a paste. This paste will help to neutralize the acid in the battery and restore its ability to hold a charge.

Step 2.1: Apply the Paste to the Terminals

Apply the paste to both the positive and negative terminals. Make sure to cover the entire terminal surface.

Step 2.2: Let it Sit

Let the paste sit on the terminals for 10-15 minutes. This will allow the baking soda to neutralize the acid and restore the battery’s ability to hold a charge.

Step 3: Mix the Hydrogen Peroxide and Distilled Water

Mix 1 part hydrogen peroxide with 2 parts distilled water to create a solution. This solution will help to clean the battery and restore its ability to hold a charge.

Step 3.1: Pour the Solution into the Battery

Pour the solution into the battery through the filler hole. Make sure to pour slowly and carefully to avoid spilling the solution.

Step 3.2: Let it Sit

Let the solution sit in the battery for 10-15 minutes. This will allow the hydrogen peroxide to clean the battery and restore its ability to hold a charge. (See Also: What Is Considered Low Voltage on a Car Battery? Warning Signs Revealed)
