Key principles related to the use of hearing aid batteries include:

• Never insert both new and used batteries into the hearing aid at the same time.

• Do not insert different types of batteries into the device at the same time.

• Used batteries should be removed from the device immediately.

• All batteries in the device should be replaced with new ones.

• Before inserting a new battery into the hearing aid, remove the protective sticker, wait 2 minutes, and only then insert the new battery into the hearing aid.

The primary type of battery for hearing aids is zinc-air batteries. The main principle of their operation is the use of oxygen from the air. Oxygen reacts with the porous membrane inside the battery. The resulting molecules travel to the anode in the form of zinc gel/powder. As a result of subsequent reactions, electrons are released, which are already set in motion by electrical energy. The current generated can power the device. The use of air affects how we should handle this type of battery.

Below we remind you of the basic rules for using hearing aid batteries, adherence to which will help maintain their lifespan:

• After removing the protective sticker, allow the zinc-air battery to aerate freely (wait about 1-2 minutes before inserting it into the device).

• When programming the device, use fresh and efficient batteries, as the most energy is consumed in these processes.

• Store batteries at room temperature.

• Store batteries in their original packaging. Do not let them touch metal objects.

• Do not allow children to play with batteries.
