Factors that affect the battery life of your hearing aid

Factors that affect the battery life of your hearing aid

It’s very annoying to talk over the phone and suddenly feel all alone as your battery has already died on its second day. Don’t worry; robustalive.com researchers and experts have found all the culprits behind the fast draining of your battery.

We will explain all the factors affecting your hearing aid battery.

Maybe the battery isn’t low

Some models have a feature that alerts you as soon as the battery starts to get low. That means these are only the warning signs, and your hearing aid battery is not entirely dead. Besides, as mentioned above, the altitude change and the humidity temporarily causes the charge dip and triggers the low battery signs.

To end the alarm, remove the battery for a few seconds and then put it back in. It will help you to get a few more hours from this battery and maybe a whole day.

Moisture affects the battery life

Humans are among the few species that produce moisture through their skin. We do it to cool down our body temperatures. Besides, moisture benefits in getting rid of the sodium and toxins in the body.

It may be possible that you are living in a moist and humid climate. This additional moisture can clog your air vent and make it less efficient. In addition to clogging, it can react with the battery chemicals, resulting in faster draining.

Here are a few preventive steps that you can take to prevent the battery from draining from moisture.

  •       Open your battery doors while storing the hearing aids.
  •       If you are not using your hearing aids for several days, remove the batteries
  •       Getting a dehumidifier for your hearing aid works perfectly
  •       Don’t keep your hearing aids in the kitchen, bathrooms, or any other moist environment

Altitude changes can impact the battery

The hearing aid batteries can deplete faster if you are going from a low to high altitude, especially if you are using the older one. Bring some extra batteries with you when climbing, flying, skiing, or doing such activities.

Advanced hearing aid features result in faster drainage

Have you upgraded your hearing aid with advanced features, and now your battery is draining faster than the one you had before? If you notice them, the advanced features can result in faster battery drainage. We are not asking you to stop using these features. But making you aware they can result in fast battery drainage.

Multichannel, Bluetooth, tinnitus relief and all these features can result in the fast drainage of your battery.

Improper battery handling

Before pulling the tab from the battery, wait till you are going to use your hearing aid. Before touching your hearing aid, ensure your hands are clean and don’t have any skin oil or dirt on them.

Unfortunately, freezing hearing aid batteries will not lengthen the battery life, unlike other batteries. Such general handling mistakes can make the batteries drain faster.

Getting a whole year’s supply is not a good idea.

You may think the bulk purchase is brilliant if you can afford it. But the last few batteries in the pack will not have their full power. Unless you are willing to waste your money, try to stay within the six-month supply.

Buying batteries on the web

I am not a critique of buying stuff in cyberspace. There are some fantastic and eye-catching deals out there. But unfortunately, some dishonest sellers are selling batteries that are about to expire. Some of them have even passed their expiration date.

You need to take care of such things to get the most out of your hearing aid battery. Purchase from a reliable source to ensure quality.

Now there are rechargeable hearing aids

There are many reasons for the fast drainage of hearing aid batteries, but all of the precautions mentioned above are useful. If you are purchasing a new set, you can also use rechargeable hearing aids.

You can charge them every night to use for the next whole day. Besides, you will have to replace these rechargeable batteries every few years.

Your Hearing aid charger can be the issue

If you are already using a rechargeable hearing aid and its battery isn’t lasting long, then the charger can be the culprit. You can check it by placing the problematic hearing aid on the chargers’ opposite side. For example, if the right hearing aid doesn’t last long, charge it on the blue side of your hearing aid charger.

If you have identified the problem, get a new charger for your hearing aid. You will have to purchase a new one as the chargers are not under warranty from the manufacturers.

These days almost all rechargeable hearing aid batteries are designed to last longer than 24 hours; if your battery isn’t lasting for a whole day, consider replacing them. To do this, you must send your hearing aids back to their manufacturers.

Hearing aids generally have lithium-ion batteries. These batteries are the same as the ones we use on our laptops and smartphones. With time these batteries start to last fewer hours as compared to earlier. But in general, people use these batteries for about 4 years before getting a replacement.


You may be enjoying conservation with your loved one or maybe watching something important on TV, and suddenly, you hear the irritating beep sound. This sound indicates that your battery is running out.

You can avoid this as you already know all the factors due to which your one hearing aid battery is dying before the other. You also know the precautions you can take to avoid it.
