& Iquest; How do hearing batteries work?

The most common type of hearing aid batteries use Zinc-air technology, which uses air from the atmosphere as an active ingredient. The tab keeps the internal ingredients isolated from the air so that the holes in the battery, to activate it, increasing its voltage until reaching the ideal voltage. Battery will not discharge and maintain its useful life.

Once the tab is removed, let the battery breathe for 1 minute, which means that the air will enter through the tiny holes of the battery, to activate it, increasing its voltage until reaching the ideal voltage.

& Iquest; What auditory battery to use?

Hearing batteries come in 4 sizes: 10, 13, 312 and 675.

The size to be used depends on the hearing equipment. Each works with a specific battery size.

On the recommendation of their audiologist, each user should have knowledge of the battery size that their equipment requires.

Each size is identified with a color, according to the standardization of the electronic auditory battery industry for all brands on the market.

& Iquest;How long do the hearing batteries last?

It is common for people to ask how long their auditory Rayovac batteries will last.

There is No answer that works for all hearing aid users. The best way to understand battery life is for each user to compare their battery performance over time.

The following table shows the ranges of results according to each size, tested against different factors.

Model 10: between 3 – 10 days

Model 13: between 3-12 days

312 Model: between 6-12 days

675 model: between 9 – 20 days

& Iquest; What factors can affect the duration of hearing batteries?

There are many factors that affect the duration. Below, we detail the most common:

Size:According to the physical size of the battery, the amount of space for the ingredients needed to power the battery decreases. Therefore, smaller batteries could last less.

Degree of hearing loss: As hearing loss is more severe, greater amplification will be required. This can reduce the duration of batteries.

Altitude:Increasing altitude produces less oxygen in the air, which generates lower voltage and can reduce battery life.

Humidity:Batteries can dry or absorb moisture depending on the level of humidity. Both results can reduce battery life.

Noise:At more noise in the environment and constant volume adjustments of your hearing aid, the battery can prematurely drain your energy.

Different auxiliaries:The characteristics of today’s hearing aids, such as wireless transmission, can reduce battery life from 20 to 30% depending on the frequency of use.
