The lifespan of a hearing aid battery hinges on a variety of factors like its make, type, capacity and amount of use.
Types of Hearing Aid Batteries
Though rechargeable hearing aid batteries exist, the most popular type is the zinc-air button. There are five sizes: 5, 10, 13, 312 and 675. They are color-coded for identification purposes.
Battery Change Frequency
You will know it is time to change your hearing aid batteries when you have to increase the volume on a regular basis. Distorted sound is also an indicator that it is time for a replacement. Certain makes of hearing aid batteries are designed to beep when the juice reaches a low level. If you hear this alarm, it is time to switch the batteries out immediately. Some makes will even lose power in a moment’s notice so be sure to carry another set with you wherever you go. Beware of the potential for these backup batteries to discharge if kept near keys, metal objects or coins.
Hearing Aid Seals
There is a seal on unopened hearing aid batteries. If you find that the seal on your new batteries is broken, don’t use them. The batteries actually begin to discharge as soon as the seal is broken.
How to Slow the Battery Drain
A common mistake many people make is keeping the hearing aid on when it is not in use. If you don’t plan on using your hearing aid for a while, go ahead and remove the battery altogether. Extraordinarily high or low temperatures can also cause the battery power to rapidly decrease.
