Why is the difference in the price of hearing aid batteries?
For hearing aid users, whether it is an ear-back or an in-ear machine, the battery is an essential consumable during wear. For an 70 decibel ear, with an 312 model batteryHearing aid4 batteries are needed in a month, so 48 batteries are needed in one year. The two ears are almost 100 one year. If you import one 4 dollar, one year 400 battery, domestic battery only needs 150 yuan. The price difference is so much, so where is the difference between them?
Explain this problem with an analogy that everyone knows well. When the lighting used in our home encounters a voltage instability, it will flicker and flicker, and the bulb will be broken seriously, so the hearing aid is the same. If the voltage is not stable enough, it will not only interfere with our listening to the sound, but the sound will suddenly become smaller or smaller, and it may damage the hearing aid! Good battery power is a long-lasting level, and the poor hearing aid power is gradually weakening. Therefore, it is best to use one for the children and the young people who need to work.
