Does temperature have an effect on the use of hearing aids?
In terms of hearing aids, batteries are one of the most important things. Hearing aids require a high-quality hearing aid battery to obtain a stable power supply for proper and correct operation. Low battery or defective batteries can seriously affect the performance of hearing aids.
Does temperature affect the use of hearing aid batteries?
Among all environmental factors, temperature is the biggest factor. This is related to the temperature-dependent electrochemical reaction that occurs at the electrode/electrolyte interface, which can be considered the heart of the battery. As the temperature drops, the reaction rate of the electrode also decreases, and the current decreases. When used, it takes a lot of energy to gradually return to room temperature. As the temperature rises, the reaction rate of the electrode also rises, the current increases, and energy is consumed. The general temperature of the refrigerator is 0 ~ 10 ° C, which is a good place to put the battery. The second factor is humidity. Zinc air battery is characterized by direct connection to the surrounding atmosphere. If the relative humidity is too low, the electrolyte in the battery will slowly dry out; the relative humidity is too high, the system will store moisture, both of which are opposite to the performance of the zinc empty battery. . If you store the battery in the refrigerator, don't forget, the refrigerator also provides a low-humidity environment, just like the uncovered food in the refrigerator, the food will gradually lose water and slowly dry. So it is best to put the battery in an anti-evaporation package.
Hearing aid batteries are zinc batteries because the discharge time of the battery is related to temperature. The lower the temperature, the shorter the discharge time. The winter weather is too cold, the temperature difference between indoor and outdoor is large, resulting in a significant shortened battery life. You can put the battery in your hand and put it in your hands for a few minutes. Remember not to put the battery in an electronic drying box. The electricity will run very fast.
Several factors affecting the battery life of hearing aids
Foreign surveys* show that the individual life of the battery varies greatly, and the user feedback time can only fall within a very wide range. The same 312 battery has a length of 12 days, and some only have a short 3 day. Therefore, the best way to understand the battery life is to use the following five factors to calculate according to the user's usage habits.
First, the degree of hearing loss
The heavier the hearing loss, the greater the amount of power that needs to be consumed in the amplified portion, and the shorter the battery life.
Second, the sound environment factors
Surrounding noise can affect battery life, and the quiet library environment consumes less power than noisy restaurants or rock concerts. In addition, if the volume of the hearing aid is adjusted to "maximum", the battery's power will be consumed prematurely.
Third, personal habits
Battery usage days are generally estimated using 8 hours per day. In fact, different wearers use different lengths of time a day, and the same wearer does not use the same length of time every day. In short, the longer you use each day, the fewer days you can use.
Fourth, hearing aid function differences
The more advanced the hearing aid, the higher the battery requirements. Some common digital functions, such as wireless functions, FM device usage, work indicators, work beeps, and function buttons, increase power consumption when turned on. This is undoubtedly an important reason for the shortened battery life.
According to the power consumption from small to large, the following figure lists the power requirements of some advanced hearing aids (mAh). It can be seen that the power consumption of using advanced functions has risen sharply compared to simple work. So, if you use the wireless function of a hearing aid, the battery life will of course be much shorter than when the hearing aid is simple to work.
Please use a reliable brand battery for hearing aids. The many functions of the hearing aid are very easy to use, but the power consumption is also more. It is recommended to use high-energy, stable imported brand batteries to ensure that these functions can be used normally.
V. Natural environmental factors
When the humidity is lowered, the battery may be shortened due to being too dry.
When the temperature is lowered, the battery voltage is lowered to cause a shortened life.
When the humidity is too high, the battery may interfere with normal discharge due to moisture.
When the altitude is raised, the decrease in oxygen in the air increases power consumption.
The above share the five factors that affect the life of the hearing aid battery, followed by battery tips to get the best performance from your battery.
