A common problem with hearing aids and their users is the constant awareness of having to change the batteries inside their instruments. Now you may be wondering why this is still a problematic issue in this day and age of long-lasting mobile energy source. But unfortunately, many things factor into why this has yet to be resolved. Before we dive into the all-important question of when you should change your hearing aid batteries, it’s important to understand why this problem is still being practiced today.
Batteries come in a variety of forms. There are SLI (starting-lighting-ignition) batteries to help power the ignition of our car’s engine and accessories, AA and AAA batteries used in our remote controls, and lithium-ion batteries used in our smartphones. The batteries mentioned above have a long-lasting lifespan and can be used for weeks or even months without having to be replaced.
Unfortunately, hearing aids, due to their size, require a compact energy source to fit into its shell. That is why zinc-air button batteries are most commonly used in hearing aids today. But zinc-air button batteries are non-rechargeable and they die out sooner than you would expect.
You’d think by now someone would have created a rechargeable energy source for hearing aids. But rechargeable batteries are just too tiny and do not have enough energy to power hearing aids to last a day. Also, hearing aids may need to be specially designed to support rechargeable batteries, which is still a problem the manufacturers are continuously trying to solve today.
How To Care For Your Hearing Aid Batteries
Batteries last about a week, depending on their size, and need to be constantly changed. But don’t fret, some people were clever enough to figure out a way to maximize hearing aid battery life. Firstly, turn them off when not in use and open the hearing aid battery locking dock so the battery doesn’t uselessly drain itself. Also, make sure you store your batteries or hearing aid at room temperature and keep them dry.
Hot and humid conditions will affect the longevity of your batteries. Some have even tried freezing their batteries thinking it would preserve battery life, but it just increases the possibility of rendering your batteries useless due to unwanted condensation.
When To Change Your Battery
Now that we’ve covered everything you need to know about your hearing aid’s batteries, let’s talk about understanding when it is the right time to change them.
The first thing you’ll notice when your hearing aid battery is dying out is a sudden distortion of sound. This is your hearing aid being less effective because it is almost out of power. It will be difficult to hear clearly though you have your hearing aid mounted on. If you have certain hearing aids, they might produce a signal or a buzz that acts as an indicator when the battery is low. It is best to quickly swap out your batteries because they die out quickly this way.
Rapid growth in science and technology has greatly influenced our day-to-day lives. Who knows? Maybe someday they may manufacture rechargeable hearing aid batteries so we won’t have to constantly replace them every now and then.
