Question
What is the life of an unused battery post year 1, 2, 3, and 4? Do thinner components being used have a greater risk of perforation?
Answer
Unused hearing aid batteries lose about 3% of their capacity every year. Batteries do fade; this is true across all battery brands. After year 4 the battery should have about 85-88% of its original capacity.
Perforations will not occur. While the steel we use is thin, the cell is structurally well supported. We have not seen any instances of perforations. You could probably stand on our batteries and they would support you pretty well!
