What is white powder on old batteries?
The battery contains potassium hydroxide, an electrolyte. When this material leaks out of the old battery and meets the air, a white crystal is formed. That is the identity of the white powder you find on the surface of old batteries.
Is the white powder from the battery harmful to the human body?
It can be harmful to the human body. Red spots may appear if the leaked material comes into contact with the skin. Also, the batteries contain zinc and manganese, so you need to be more careful. Inhaling zinc oxide powder can lead to chills and fever, ‘zinc poisoning’. When this powder enters the lungs through breathing, it attaches to the lungs and decreases breathing ability, causing inflammation and sputum with blood. Manganese can also cause ‘manganese pneumonia’.
What should I do if it gets on my hands
You should wash your hands immediately with running tap water and soap. If you have any abnormal symptoms such as skin irritation, it is recommended to consult a doctor. And to prevent this situation, be sure to put the old batteries in the battery disposal box!
