Hearing Aid Batteries...

Here is some information about hearing aid batteries that you should know...

How Hearing Aid Batteries Work.
The most common type of hearing aid batteries on the market today are zinc air batteries. Zinc air batteries need air to activate and power up. Once the tab is removed, you can see the tiny holes in the battery; these holes are what allow air to enter the battery and power it up. Make sure you let the battery sit for 1 minute un tabbed before inserting the battery into the hearing aid. The reason to let it sit is because the air needs time to get into the battery. If you take the tab off and immediately put the battery in the hearing aid, you limit the amount of air it is exposed to. This could cause the battery to seem “dead” because the voltage could not reach the necessary level to power the hearing aid. If this happens when you first put the battery in the hearing aid, take the battery out and let it sit. This allows air to enter the battery cell and increase the voltage. After 1 minute, put the battery back into the hearing aid.

Standard Battery Color code. All hearing aid batteries conform to the following color code no matter what brand the batteries are. If you are not sure what the number size is when you are shppoing for batteries, you can match the color of your old package to the color of the new one and it should match. The color code is as follows:
YELLOW = #10
BROWN = #312
ORANGE = #13
BLUE = #675

 Battery Life.
How long should your hearing aid batteries last? The truth is there is no one answer that will work for every person. There are a number of factors that affect how long a battery will last and each person has a different combination of these factors. Essentially each person has a unique hearing loss “fingerprint”. No one fingerprint will be exactly alike; therefore, no one person will have the exact same battery life as another.

Factors that affect battery life include:
The individuals hearing loss. As the severity increases, increased amplification is required. This causes an increase in the current required to power the hearing aids. Higher current requirements equal shorter battery life. 

Hearing aid usage.
Some people may wear their hearing aids only 4 hours a day. Some wear their hearing aids 12 hours or more each day. The daily usage time will affect the battery life. Also making sure you open the battery doors when the aids are not in your ears (so they are turned off) will make a difference in the battery life.

Hearing instrument itself. 
The more advanced the hearing aid is the more power is required. New digital hearing aids are like miniature computers. Some are capable of processing huge amounts of data. The more features they have, the greater the power it takes to operate them is increased.

The environment. 
Humidity, temperature and altitude all have an affect on the life of your hearing aid batteries. As humidity is reduced batteries may dry out reducing the battery life. High humidity can affect batteries by causing increased moisture in the battery that will interfere with the normal discharge rate of the battery. As temperature lowers the battery voltage also lowers reducing battery life. Altitude can also affect battery life as the amount of oxygen in the air changes with altitude. Less oxygen equals less voltage. Less voltage equals less battery life.

Battery tips: 
Store your batteries at room temperature, do not carry batteries loose in your pocket or purse. They could come into contact with a metal object like a coin or keys and create a short circuit that could cause the battery to cause a burn or could cause the battery to explode. Carry them in a battery holder or in the package they came in. Use fresh batteries. Batteries do have a good shelf life but over time temperature fluctuations and air seepage can shorten the shelf life. Batteries should not be stored in a refrigerator.
