differences of hearing AIDS batteries – quality and shelf-life
With increasing age, the hearing ability decreases in many people. But with the help of a hearing aid are hard of hearing can participate again in the life of society. How to maintain a hearing aid at the best, you can find here. Thus, a hearing aid can work, it will need the appropriate batteries.
The common hearing aid batteries
Hearing aid batteries are zinc-air batteries, specifically developed for power supply of hearing AIDS. They have the Form of a button cell, and are characterized by their high energy density, which is required for a consistent energy supply of the hearing aid. Zinc-air batteries are not rechargeable.
To facilitate the purchase of the right battery size, were characterized by the different types of hearing aid batteries with different colors. These colors are usually seen on the packaging and the foil, which protects the small battery. The hearing aid batteries that are currently used most often are the one with an orange, brown and yellow color scheme. The battery with the orange slide has the number 13 and has a diameter of 7.80 mm and a thickness of 5.35 mm, while the with the brown color scheme, number 312, and a diameter of 7.80 mm, and a thickness of 3.45 mm. The battery with the yellow color scheme has the number 10 and a diameter of 5.80 mm and a thickness of 3.55 mm.
Furthermore, there is the hearing aid battery with a blue color scheme, this is with a diameter of 11.56 mm and a thickness of 5.33 mm, a little larger than the other batteries and found only in a particularly strong hearing AIDS use. The smallest hearing aid battery has the color scheme of red and a diameter of 5.80 mm, and a thickness of 2.16 mm, and in Germany rarely used, since it can only fit in small hearing AIDS.
Quality and durability
How long a hearing aid battery depends on the power consumption of the corresponding hearing aid. It makes little sense to buy as many batteries on stock, because zinc-air batteries due to self-discharge, losing about three per cent of its capacity in a year. This is because the batteries have air holes on the positive pole, which are sealed by a protective film, but from which, nevertheless, energy is released. You should remove any case, the protective film until shortly before Loading the battery in the hearing aid, since a premature Stripping of the film, which loses battery of increasing capacity.
Who cares for his hearing aid good, can increase the durability of its batteries. These should be stored in a dark place at normal room temperature. For the batteries of the present Generation, the fridge is not a suitable place of storage. Which is the battery manufacturer produces the best hearing aid battery, is not known. However, the leading battery manufacturers are increasingly working on the improvement of the hearing aid battery.
Rechargeable Hearing Aid Batteries
Rechargeable hearing aid batteries are an environmentally friendly Alternative to the zinc-air batteries. However, rechargeable button cells, are not for every hearing aid is suitable. Since the trend is to develop ever-smaller hearing AIDS, the batteries always tiny. Therefore, a battery must be charged in the size of a button cell battery already after a short time, what is often perceived as too cumbersome.
