Battery Life
How long should your batteries last?
Each person has a unique hearing loss “fingerprint.” No one fingerprint will be exactly alike, so no one person will have the exact same battery life as another.
The best way to get a good estimate on what your battery life should be is for you to test the battery. Write down the date you put in the battery and when you take it out. Once you have used all of the batteries in the package, you should be able to have an estimate of how long your battery will last.
Factors That Affect Battery Life
Individual’s Hearing Loss
As severity increases, increased amplification is required. This causes an increase in the current, which reduces battery life. Therefore, the more severe of a hearing loss a person has, the shorter the battery life. Also, hearing loss can be worse in one ear. That means you shouldn't expect equal battery life for each hearing aid.
Individual’s Hearing Aid Usage
Most people refer to days when referencing battery life, but what is the definition of “a day” to each person? Some people only wear their aids 4 hours a day, while others wear them 16 hours a day. “Hours” is a more accurate way to calculate battery life.
The Hearing Instrument Itself
The more advanced the aid is, the more power is required. This concept is similar to a cell phone. The more features you use on your phone (internet, apps, games, movies, etc.), the faster the battery dies. New hearing instrument accessory items also put more drain on the hearing aid battery.
Environment Humidity
As humidity is reduced, batteries may dry out, thus reducing the battery life. This can be an issue if you are indoors during the winter months in northern climates, use a wood-burning stove to heat your home, or keep batteries in a dry-aid kit in an already dry environment.
Temperature
As temperature is reduced, hearing aid battery voltage is lowered, which reduces battery life.
Altitude
At higher altitudes, the percentage of oxygen in the air is reduced, lowering the hearing aid battery voltage. This can cause the battery to reach its endpoint earlier.
Personal Environment
The noise around you can affect battery life. A battery will drain less in a library than in a restaurant or at a rock concert. Turning up the volume on your hearing instrument in a noisy setting can prematurely drain the battery.
