Many parents want to know how to buy and use hearing aids correctly?
At present, most of the hearing aid batteries use zinc air batteries, which have the advantages of long discharge time, large battery capacity, stable current discharge, and environmental protection. However, the zinc air battery has a low voltage and is a disposable chemical reaction battery that cannot be used for charging.
The use time of the hearing aid battery depends mainly on three factors: battery usage, hearing aid power consumption, and external environment.
First, the factors of battery use:If it is allowed, it can be placed for 3-5 minutes before use, and the battery life of the hearing aid can be extended. The hearing aid battery must be peeled off when it is needed, and the battery should be removed without a hearing aid for a long time.
2, usually do not put the hearing aid battery together with metal objects, to avoid metal short circuit caused by friction of metal.
3, the shelf life of the battery: zinc air battery storage capacity is natural loss, long-term storage of electricity will decline, the general environment will lose about 10% per year. The natural loss rate of different brands is different, so the shelf life of different brands will be different, usually between 2-4 years. In principle, the longer the shelf life, the more mature and stable the product process.
Second, the factors of hearing aid power consumption:
1. The overall design of the hearing aid is the main reason that affects the power consumption of the hearing aid. Different chip microphone receivers and circuit design will affect the power consumption. Generally speaking, the more advanced products and brand manufacturers, the more balanced and reasonable between product functions and power consumption.
2, the function of the hearing aid is different, the power consumption will also vary greatly. At present, with the development of high-tech digital technology, the functions of hearing aid chips are more and more, and the power consumption is also increasing. For example, wireless functions, use of FM devices, work reminder lights, work prompts, and function buttons are turned on. Will increase power consumption;
