Sometimes, when opening the battery compartment, the user may discover the following: The surface of the batteries is coated with a whitish, salt-like deposit. In some cases, it resembles a mixture of paints. Furthermore, an unpleasant odor will emanate from the compartment.
This phenomenon raises the question: why do batteries oxidize and how can this be dealt with?
Reasons why batteries oxidize
Below are a number of causal factors.
- Energy sources are saline and of poor quality.
- Expired.
- Batteries from different companies and with different charge levels were used. They may have different internal resistances. This can accelerate their failure and lead to oxidation.
- Depressurization of the housing due to a defect in the housing.
- Activity of a chemical reaction.
This is what causes batteries to oxidize.
Why does the oxidation process occur?
These elements are designed in such a way that they tend to oxidize. By undergoing this process, the current source is capable of releasing energy. The fact is that manganese dioxide is reduced during operation of the current source, while zinc oxidizes at the same time. This is what produces current.
It contains various substances, such as zinc chloride and potassium carbonate. Incidentally, if it contains salts, it will leave a yellow coating.
