Different Types Of Batteries
There are four main sizes of batteries, each with a specific color-coded package: size 10 , size 13 , size 312 , and size 675 . The battery size you need is typically based on the size and style of your hearing aid.
Standard hearing aid batteries are zinc-air, which are activated when exposed to air, so it is very important to keep them sealed in their packages prior to use. Never open packages to move batteries to a single container; keep the packages sealed until the batteries must be used in the hearing aids, or you may end up with a dead battery. Dont buy batteries if the seal is broken.
Where To Buy Hearing Aid Batteries
Hearing aids can be purchased at a specialist hearing care provider, but they can also be found online as well as in pharmacies, electronics stores or sometimes even grocery stores.
If you are unsure about what the best hearing aid batteries are for your devices, it would be advisable to speak to a hearing care specialist.
Moisture Can Drain A Battery
Did you know that humans are one of the few species that release moisture through their skin? You do it to cool off. You do it to get rid of excess sodium or toxins in the blood. On top of this, you may live in a humid or rainy climate where things get even wetter.
This extra moisture can clog the air vent in your device, making hearing aids less efficient. It can even drain the battery directly by interacting with the chemicals that produce electricity.
Here are a few steps you can take to avoid moisture-caused battery drain:
- Open the battery door before storing the aids
- Dont leave the batteries in if youre storing them for several days
- Get a dehumidifier
- Dont keep your hearing aids in the bathroom or kitchen

Now that you know the answer to how long does a hearing aid battery last? lets look and when to change batteries. Its a good idea to always have replacement batteries on hand, in case your current batteries die.

Why Do Hearing Aid Batteries Drain So Fast
The life of the hearing aid batteries is affected by the humidity in the air. If you live in a place that is humid and moist, the additional moisture can clog the air vent in your hearing aid. This will affect the efficiency of both the battery and the hearing aid as moisture interacts with the chemicals of the battery, resulting in fast drainage. Usually, standard hearing aid batteries last anywhere between 3 to 22 days.
How Hearing Aids Help You Hear Better
Hearing aids are the best treatment for a person suffering from hearing loss. They make sounds louder so you can enjoy conversations and other activities that require hearing. Using a microphone, amplifier, and speaker all of which are powered by a tiny battery the hearing aid receives sound and turns it into an electrical signal, which is passed on into your ear. Since most hearing loss involved damage to hair cells, which are the sensory cells that allow us to hear, hearing aids target the remaining undamaged hair cells with the amplified sounds.
