This hearing aid battery uses zinc-air technology to power up devices. It utilizes the oxygen from our atmosphere that passes through the small hole in the case allowing the air to react in the battery. Its own perforated compartment makes it stay secured in its place. Unless the plastic seal is removed, you can store it for a longer time in cool dry place.
13 (orange) hearing aid batteries are manufactured free from mercury to make it safe for both the environment and the hearing aid user.
