Hearing Aid Batteries

Hearing aids must operate from a power source.  This power source is the hearing aid battery.  The majority of hearing aids run on disposable batteries.  There are a few hearing aids that operate on a re-chargeable battery system.  For the purpose of today’s post I want to focus on the disposable hearing aid battery.

Hearing aid batteries come in 4 different sizes (size 10, 13, 312, and 675).  Each hearing aid is designed to work with a specific size battery.  Your audiologist will discuss with you what size battery works with your specific hearing aid.  The hearing aid battery sizes are also color coded, size 10 (yellow), size 13 (orange), size 312 (brown), size 675 (blue) this can make it easy to pick out the right size when you call to order or pick up in a store.

One of the biggest concerns with hearing aid batteries is how long they last.  Each size of battery has a different length of time it can last.  Size 10 batteries are the smallest and may only last a few days while a size 13 battery may last closer to 10 days in your hearing aids.

Regardless of battery manufacturer there are a few things to look for and do to increase battery life:

  1. Confirm on the back of the package that the batteries are 1.45 volts and not 1.4 volts.
  2. Store hearing aid batteries in a dry place.
    1. Do not store in the bathroom
  3. When it is time to replace a battery in a hearing aid, remove the battery from the package and peel the sticker from the battery.
    1. Before placing the battery into the hearing aid let the battery rest on the table for 3-5 minutes
    2. Hearing aid batteries are charged by exposure to the air so letting the battery air out for 3-5 minutes allows them to come to a full charge before putting them to use in the hearing aid

Following these above steps can help maximize the length of time a hearing aid battery can last for you.


Can Hearing Aids Be Passed On

I had a patient who recently purchased a new set of hearing aids.  He is 87 and in good health but understands he is nearing the twilight of years.  He wants to continue to strive for the best possible quality of life and stay connected to his family and friends but also wants to know that if he makes a significant purchase on hearing aids they could be passed on in a final will.

This is a very common question and the answer is, YES, but it is much easier to pass on if the hearing aids are receiver-in-the-canal (RIC) or behind-the-ear (BTE).  The reason for this has to do with the model of hearing aids.  When the RIC or BTE models are used, the body of the hearing aid is not custom fit to the patient.  What is customized is how the hearing aid adjusts for the patient’s hearing test results.  This means that to pass a RIC or BTE hearing aid on all that may be required is a reprogramming of the internal computer software.

Each clinic may be slightly different but most often there will be a fitting or reprogramming fee involved to adjust the hearing aids for a new patient’s hearing.  The fee is often similar in price to a co-pay for a visit, but could vary considerably depending on the policy for certain clinics.

If you have questions about your specific hearing aids or if you would like to know if your hearing instruments could be gifted or passed on to family or friends call Dr. Griffith with Accessible Hearing Aids at 504-738-4557.
