All hearing aids have batteries and they come in several sizes. These are size 10, size 13, size 312 and size 675. At our office you can buy various sizes zinc-air batteries suitable for your hearing aids.
Zinc-air batteries are batteries for hearing aids powered by zinc metal and oxygen. Because zinc-air batteries are air-activated, a factory-sealed sticker allows them to remain inactive until it is removed. Once that sticker is removed, the battery begins draining. Therefore, the sticker should only be removed when you want to activate the battery. Once you have removed the sticker let the battery sit for several minutes to fully activate before actually putting it in your hearing.
There are several factors that determine the life of a hearing aid battery – environment, the use and type of hearing aid.Two long beeps indicate the hearing aid battery is low. After the low battery warning, sounds may not be as clear. This is normal and can be fixed by changing the batteries. If you can’t hear the low battery warning, our hearing prosthetic specialist can change its pitch or loudness. If you prefer, it can be turned off entirely.
If you notice that your hearing aid sounds weak, hearing aid produces crackling sound or does not work properly, it may also indicate that the battery is running out. It is always recommended having a new battery handy, so you can change it at any time and avoid unpleasant surprises.
If the battery changing bothering you, you can buy a Battery Charger for Hearing Aids!
