Why do I have to change my hearing batteries so often?


As an audiologist this is one of the questions that we get asked the most. But the answer is going to be different for everyone. We can provide you with an expected range of battery life but ultimately after you wear your hearing aids for a couple of months you will notice a pattern of how often you need to change your battery.

The size of the battery

The larger the battery the longer the life of the battery. As hearing aids get smaller so too does the size of battery. With a smaller battery comes a shorter life. So when picking a hearing aid you have to decide how often you want to be changing the battery. Some of the smaller hearing aids you may need to change the hearing aid every 4 to 5 days. Some of the larger hearing aids you can often change every 10 to 14 days.

Your hearing loss

Individuals with greater hearing loss are going to need more amplification or power. The more power you need the shorter the battery life.

How much you wear your hearing aid

How many hours a day you are wearing your hearing aid will change your battery life. Someone who wears there hearing aid 9 hours a day will have a longer battery life than someone who wears there hearing aid 14 hours a day.

The environment

The features of your hearing aid
