Does Cold Weather Affect Hearing Aid Batteries?

  1. Hearing Aid Batteries

Thousands of individuals possess some degree of hearing loss. A fair percentage of such people utilize hearing aids as a means of circumventing the loss of hearing. That said, a solid percentage of these devices are comprised of intricate components that could be impacted by external conditions like cold weather.

At Beltone Dallas Fort Worth, we invite you to read the following brief blog highlighting the specific adverse impacts cold weather can exercise over a hearing and the steps owners can execute to prevent these potential pitfalls.

Cold Weather Impacts Upon Hearing Aids

Diminished Battery Life

The batteries that power many hearing aid devices contain a substance known as zinc. Decreasing air temperatures weaken zinc’s effectiveness. Therefore, continued cold exposure will weaken the batteries, which could impact the unit’s efficiency and necessitate untoward actions such as more frequent recharging or the purchase of new power sources.


Hearing aids that are exposed to cold temperatures stand at greater risk of developing condensation. This natural process occurs when a cold device develops moisture after returning to warmer air. Moisture can exert a significantly adverse impact upon the unit’s electrical wiring and other components. Over time, the device’s efficacy could be threatened and might eventually be rendered useless.

Signs A Hearing Aid Has Been Exposed To Moisture

Inconsistent Operational Patterns

The consistency of your hearing aid changes frequently. Literally, one minute the device operates properly and a few minutes later might not.

Sound Irregularities

Moisture often causes a hearing aid’s sound to fade. Users may notice diminished sound production emerging from the speakers.


Much and, in some cases, all the produced sound is accompanied by hissing or humming static.

Complete Shutdown

Should water damage be extensive, a complete shutdown might occur.


Fortunately, you might avoid these issues by adhering to the following precautions:

Ensuring Your Ears Remain Covered While Outdoors

Protecting your ears is not only good for your general health but also for your hearing aid’s well-being. Partaking in this decreases the device’s chances of being exposed to cold air. Therefore, when outside during the wintertime, hearing aid users are encouraged to wear protective coverings like ear muffs, hats and scarves.

Remove Batteries

Hearing loss experts recommend that you remove the device’s batteries when it is not in use. For example, if you are going to spend extended durations outdoors but not require your hearing aid, the batteries should be stored in a sealed case and kept in as warm an environment as possible. Therefore, this does not mean an unheated room or on the front seat of your car.

Purchase A Dehumidifier

Removing accumulated moisture with a hearing aid dehumidifier can prevent damage inducing events from occurring.
