When might a hearing aid battery expand and leak?
Answer
If the discharged battery is left in the hearing aid after end of life, humidity can influence the battery chemistry and lead to swelling, especially in extreme weather conditions such as a tropical environment. Once a battery is at the end of its life, it should be removed from the hearing aid.
