The life of a hearing aid battery is not fixed, but is affected by a variety of factors. From the battery's own characteristics to the user's usage habits, these factors are intertwined and determine how long the battery can provide energy support for the hearing aid.
The type and quality of the hearing aid battery itself are the basic factors affecting the life. Currently, common hearing aid batteries include zinc-air batteries and lithium batteries. Zinc-air batteries need to come into contact with air to produce a chemical reaction before they start to supply power. They have a limited life after opening, generally ranging from 5 to 20 days; lithium batteries have a strong endurance and can be used for several days or even a week after being fully charged, but different brands and models of lithium batteries have different capacities and performances. At the same time, good quality batteries have high stability of internal chemical substances and long-lasting and stable power supply. Inferior batteries not only have a short life, but may also leak and damage the hearing aid.
The length of time a hearing aid is used directly affects the battery life. If the user wears the hearing aid for a long time every day, such as more than 12 hours, the battery power consumption will be significantly accelerated; while if it is only used for a few hours a day, the battery life will be correspondingly extended. Just like mobile phones, the more frequently you use them, the faster the battery will be consumed, and the battery life will naturally be shortened.
The use environment is also a factor that cannot be ignored. In a hot and humid environment, the chemical reaction speed inside the battery will accelerate, which will accelerate the consumption of power; in a low temperature environment, the chemical reaction activity of the battery will decrease, the actual available power will decrease, and the battery life will also be shortened. For example, in the hot summer outdoors or the cold winter outdoors, the service life of the hearing aid battery will be shorter than in a normal temperature indoor environment.
The volume of the hearing aid also affects the battery life. The louder the volume, the higher the power consumption of the hearing aid, and the faster the battery power will be consumed. If the user often adjusts the volume of the hearing aid to a higher gear to meet their own hearing needs, the battery life will be significantly shortened; on the contrary, if it is used at a suitable and lower volume, the battery can last longer.
The function activation of the hearing aid also affects the battery life. Modern hearing aids have a variety of functions, such as Bluetooth connection, noise reduction function, induction coil, etc. When all these functions are turned on, the power consumption of the hearing aid increases significantly, which will quickly drain the battery power. For example, turning on Bluetooth to connect to a mobile phone to listen to music consumes the battery much faster than simply using the hearing aid to listen to the surrounding sounds.
The user's operating habits will also have an impact on the battery life. Irregular operations, such as putting the battery into the hearing aid without completely removing the sticker, will cause the battery to react prematurely, shortening the actual use time; and if the used battery is not removed for a long time, it may leak and corrode the hearing aid, affecting the normal use of the subsequent battery. In addition, frequently turning the hearing aid on and off will also increase power consumption to a certain extent.
The storage conditions of the battery also affect its performance when it is unopened. If the battery is stored in a poor environment, such as high temperature, high humidity or near a strong magnetic field, even if it has not been opened and used, the chemical substances inside the battery may change in advance, resulting in a reduction in the actual available power and shortening the service life. Therefore, the correct storage of unused batteries is also an important part of ensuring their service life.
