How can I choose the right batteries?
There are several types of batteries listening to the size and color coding. The size of the battery required will depend on the specific type and model of the hearing aid. Most of the hearing aids use one of the five standard cells of knob cells, each of which is a color code.
colors make it easier to select and shopping for batteries. Blue represents the most commonly used battery size, 675. Yellow represents size 10. Brown is for size 312 and orange is for size 13. Some of the smallest batteries, size 5, are coded red. Batteries for these auditory aids are made of zinc. Usually it is 1.45 volts, allowing them to endure longer and change less often.
Some cochlear hearing aids will require high -performance zinc batteries that are designed for longer life and better sound quality for certain implants. Whether a cochlear implant requires the and powerful battery or not depend on the designHU hearing aids and concrete programming of a "map" or a cochlear user implant. Some cochlear implants can get with standard zinc batteries and the use of high -performance above the standard does not necessarily promise longer battery life or better performance.
Hearing service batteries are small and round. They have a small card attached, color coded to match standard size. When this card is removed, oxygen in the air combines with zinc to activate the battery. This method ensures that the battery remains fresh and charged at the moment of purchase. The hearing aid batteries can also be tested by a small machine made for this purpose, which tells the user how much life in the battery remains.
Rechargeable batteries are also available for hearing aids. They are based on NiMH and can be charged approximately 300 times. Nna what is the chemistry of the battery, size in generalStandard among all types of hearing aids.
Standard batteries will usually take approximately two weeks. The smaller the hearing aid, the smaller the battery and the shorter the battery life. The battery life range will depend on the type of listener and amplifier class. The hearing aids should not be stored in the refrigerator, but at room temperature.
In addition, the batteries should never be forced to the hearing aid. If the battery does not fit properly, it should be carefully checked to verify the size. The user should then consult with the hearing aid documentation to confirm that the correct battery has been selected. The correct size battery should easily fit in.
