The white powder results from a chemical reaction between the copper connectors and the sulfuric acid in the battery. This reaction produces a white powder known as anhydrous copper sulfate. Sulfuric acid leaks when overcharging, causing the acid to leak and get in contact with the connectors.
Thus, the sulfuric acid in the battery leaks to the lead terminals, causing a chemical reaction that forms the white anhydrous copper sulfate or lead sulfate. Accordingly, the white powder is oxidized in moisture to the blue powder you often see on your terminals. To remove this blue powder, clean it with water and baking soda.
The whitish/bluish powdery stuff in a car battery, particularly on the battery terminals and the area that surround them, is called corrosion. It is something that is commonly found on lead-acid batteries, the battery that is being used for most cars. What Causes Corrosion?
The white powder is an end product of an electrochemical reaction between copper connectors and the lead terminals. This results in a white anhydrous copper sulfate or lead sulfate. On exposure to moisture, the white powder turns blue when hydrated.
The battery contains sulfuric acid and battery distilled water that reacts with the lead terminals causing the formation of blue powder. Sulfuric acid also reacts with the copper connectors, forming the blue-hydrated copper sulfate. Ensure the sealing cap tops are tightened and any broken caps are replaced to prevent leakages.
Use a screwdriver to loosen the connectors without damaging the lead terminals. Step 3: Apply the baking soda mixture on the battery terminals and let it react for 5 minutes. Scrub off the powder using a brush. Check on the copper connectors and scrub any powder attached to them using the baking soda mixture.
