If the acidic liquid inside the cans has turned black, then most likely the battery will need to be replaced. The electrolyte turns black when the plates are destroyed, and lead is scattered on the bottom of the cans, which stains the liquid in a dark color.

How to clean a corroded battery compartment?

If the corrosion is particularly severe, you can use a baking soda paste. Mix baking soda with a little water to create a paste, which can help neutralize acid corrosion. It’s gentle yet effective. Once you’ve gathered the necessary tools, it’s time to start cleaning the corroded battery compartment.

What if a battery color change is observed in all banks?

If a color change is observed in all banks, then a poor-quality battery may have been purchased. In many cases, in the presence of a cloudy electrolyte in banks, the battery can be fully restored to working capacity as a result of replacing the acid mixture and fully charging the battery.

Why does acid stain a battery?

When acid and water are mixed, a colorless liquid is formed, therefore, if this mixture is colored during battery operation, the reason for this phenomenon is the substances that make up the internal plates. There may be several reasons for staining the acid liquid in dark shades.
