A hearing aid is not a perpetual motion machine. If you want it to work and listen to the user, you have to input energy. Most of the digital hearing aids commonly found on the market are powered by zinc-air batteries. So, how much do you know about the knowledge of zinc-air batteries? Although there is no need to master the theoretical knowledge as a hearing aid user, some basic hearing aid maintenance methods.
Where is the zinc empty battery stored better?
Please keep in a cool dry place. High temperature, high humidity and direct sunlight are very harmful to the battery, so don't put it on the balcony, and don't hide it in the refrigerator.
Does the zinc empty battery have a shelf life?
The service life of zinc-air batteries is generally about 2-4 years. Generally, the life of imported batteries is longer, and domestic batteries will be shorter. The shelf life of the Ou Shida hearing aid battery is 4 years.
However, simulation tests have shown that at room temperature, after a year of storage, the electricity is reduced to 95%. After two years of storage, the electricity is reduced to 90%. After four years of storage, the electricity is still 85%.
So even though the shelf life of the battery is very long, it is best to look at the date of production when you buy it. Don't use too much for too long.
Do you need to take the battery out when the hearing aid is dry?
Zinc air batteries are susceptible to environmental influences, and the optimum humidity is about 60%. Too dry or too humid will shorten the use time.
When the summer rainy season or the southern spring rainy season is wet, the battery compartment should be opened every night and the battery and the hearing aid should be placed in the dry box.
If using an electronic dryer for dehumidification maintenance, remember to remove the battery first to avoid excessive drying and damage to the battery and hearing aids.
In addition, if the hearing aid is not used for a long time, remember to remove the battery. Since the zinc-air battery contains a high concentration of electrolyte (potassium hydroxide, which is strongly alkaline and highly corrosive), once it leaks, it will corrode parts near the battery, and this corrosion may be irreparable and fatal.
