Yes, button cell batteries can leak.
Button cell batteries are susceptible to leaking, especially when exposed to moisture. This leakage involves a corrosive electrolyte solution which can cause significant damage.
Risks Associated with Leaking Button Cell Batteries
- Corrosive Leaks: The electrolyte within button cell batteries is highly corrosive. If a battery leaks, this corrosive substance can cause burns and damage to surrounding materials or tissues.
- Liquefaction Necrosis: According to research, tissue in contact with leaked button battery electrolyte can undergo liquefaction necrosis. This is a type of tissue death where the tissue essentially dissolves.
- Damage Examples: Documented cases show that leaking button batteries lodged in the ear can cause necrosis of the skin, bone, and tympanic membrane.
Factors Contributing to Leaks
- Moisture: Exposure to moisture is a primary trigger for button cell battery leakage.
- Age: Older batteries are more prone to leaking.
- Damage: Physical damage to the battery casing can also cause leaks.
Prevention and Safety Measures
- Proper Storage: Store button cell batteries in a dry, cool place.
- Regular Inspection: Check devices that use button cell batteries regularly for signs of leakage.
- Safe Disposal: Dispose of used button cell batteries properly according to local regulations.
- Immediate Removal: If a battery is leaking, carefully remove it using gloves and avoid direct contact with the leaked substance.
In summary, button cell batteries can indeed leak corrosive substances, posing a risk of damage and injury. Proper handling, storage, and disposal are essential to prevent leakage and ensure safety.
