Hearing aid battery precautions

Battery is the power source for hearing aid to work normally. A good hearing aid battery should have high capacity, small internal resistance and long shelf life. High capacity can be used for longer time; small internal resistance can provide greater transient current to reduce distortion; long shelf life makes users not need to buy newly produced batteries frequently, and can reduce the loss of capacity reduction caused by the expiration of shelf life.

Why do hearing aids have to use zinc air batteries? What are the advantages of such batteries?

Zinc air battery uses oxygen in the air as the positive material, so there is no need to put it in the battery, so there is room for more negative materials in the battery. Therefore, its capacity is 3-10 times higher than other batteries, which is the highest of all applicable battery systems. The battery also has the advantages of stable working voltage and small noise. It is the best power supply for hearing aids.

There are several types of zinc air hearing aid batteries in common use. Which type of hearing aid are they used for?

There are four types of zinc air hearing aid batteries: A10 for ear canal (ITC) and deep ear canal (CIC) hearing aids; A13 for BTE and ite hearing aids; A312 for ite and ITC hearing aids; a675 for BTE hearing aids;

How long does a battery last?

The actual use time of the battery is related to the type of hearing aid, amplification power, personal hearing loss, daily use time and the volume adjusted during use, etc. the difference is very large. Generally speaking, the larger the battery used for hearing aid or the smaller the hearing loss, the longer the use time. From our understanding of the actual use, the following time is available for your reference:

A10 battery is generally used for 5-7 days; A13 battery is generally used for 7-10 days; A312 battery is generally used for 7-10 days; a675 battery is generally used for 10-15 days.

What is the tape at the bottom of the battery? Can it be reused after the battery is removed?

The adhesive tape is used to close the vent hole of the positive pole, isolate the air, and avoid the influence of various components such as carbon dioxide and water vapor in the space-time gas on the battery. At this time, the battery is in sleep state and can be saved for a long time. If the battery that has been used for a period of time is taken out of the hearing aid, and then the air hole is sealed with tape, although the battery life can be slightly prolonged, it is generally unnecessary to do so because the battery has been partially discharged and the internal oxidation reaction has occurred.

Why do some new batteries have no electricity just when they are put into hearing aids?

You may have just removed the tape or the battery temperature is too low. The air inlet at the bottom of the battery has been pasted with adhesive paper when leaving the factory. At this time, there is no oxygen in the battery and it is in the sleep state. After the adhesive paper is removed, the battery is gradually activated by air about 60 seconds later. In addition, in the cold season in the north, the battery just brought back from the outdoor needs to be used after the temperature rises to room temperature due to its low temperature.

Should batteries and hearing aids be kept in dry boxes every night?

Zinc air battery is easy to be affected by the environment, the best humidity is about 60%, too dry or too wet will shorten the use time. When it is wet in summer rainy season or southern spring rainy season, open the battery compartment every night, and put the battery and hearing aid into the drying box together. Under normal or dry conditions, do not put the battery in the drying box at night to avoid excessive drying. In most areas of northern China, batteries do not need to be dried all year round.

Do you want to take it out of the hearing aid immediately when the battery is used up or dead?

When the battery runs out or has no electricity, it will be in the state of over discharge in the hearing aid, which will easily lead to the leakage or over expansion of the battery, so the battery must be taken out immediately after running out.

Where is the unopened battery stored better? How long is the shelf life?

Please keep it in a cool and dry place. It is recommended to store it in a sealed box similar to the clasp, not in the refrigerator. High temperature, high humidity and direct sunlight are harmful to the battery. Generally, the shelf life of hearing aid batteries on the market is 2-3 years.
