Hearing Aid Batteries Explained

Hearing Aid Batteries Explained

There’s no denying just how beneficial hearing ads have been for those who suffer from hearing loss, but equally as important as these devices are the batteries that power them. Without a fresh battery or the right one, your hearing aid won’t be functioning at its maximum capacity which means you’ll be struggling to hear as well as you usually do.

Hearing aid batteries come in a few different styles and sizes but they must all be cared for in the right way in order to keep them working their best. With a little bit of care and maintenance of the batteries and your hearing instrument, you’ll ensure they last longer than usual while also keeping the device in top condition as well.

What Type Of Batteries Do Hearing Aids Use?

When looking at the right batteries for your hearing aid, it’s usually a matter of matching the size of the battery to the hearing aid. Most are labeled with color and number codes that help you choose the right hearing aid batteries sizes to correspond, otherwise, you can look at the manufacturer’s guidelines to see which ones they recommend.

Although there are different sizes, most hearing aid batteries are the same kind. Zinc-air batteries are those that are activated by oxygen and without the air, they wouldn’t be able to work. These batteries are protected by a sticker which is then removed just before use, allowing the air to get to the battery.

Because all hearing aids are different, some might last longer with a battery than others and some will require replacement more frequently. Again, it depends on the brand and model of your hearing aid and what type of batteries you’re using, but if there’s any sign that the battery is fading then you should replace it immediately.

The Advantages Of Zinc Air Batteries

The zinc-air battery is by far the most popular choice when compared to lithium-ion and other materials, and it’s all because of the advantages it possesses when looking at hearing aid technology specifically. Here are some of the benefits you can find:

  • Inexpensive materials mean lower costs for the user;
  • Technology that has been specifically designed for hearing aids and works effectively;
  • Stays sealed and at a low discharge rate when not in use;
  • Keeps a constant voltage rate once opened;
  • Lasts for a long time when used on low settings;

How To Get The Most Out Of Your Batteries

There are a few different things to keep in mind for your hearing aid batteries to ensure that they last as long as possible. As they can be costly to continually replace if you’re living on a budget, you want to do everything you can to care for them right.

  • Keep the batteries stored at room temperature at all times, and store them in a dark and dry place. Exposure to the sun can damage them and also wear down the seal that keeps them fresh.
  • Whenever you’re not wearing them, try to open the battery compartment so that they can get some air. This can prevent the battery from draining and remove any possible moisture that might be building up.
  • Any time you’re not using your hearing aid you should turn it off to prevent the battery from draining. Although they will automatically drain once the seal has been broken, it will occur at a very low rate if it’s turned off.
  • When you remove the sticker on the battery and want to start using it, you must leave the battery out and allow it to absorb air for up to a minute. This will ensure enough oxygen has reached all parts of the battery so that it will work to its maximum capacity.
  • Always store your batteries in a safe place that can’t be accessed by children or pets, as swallowing them can be fatal. Don’t leave them too long in the cupboard and always check the expiration date listed.
  • Wash your hands thoroughly before handling your hearing aid and especially before changing the batteries. Any grime or grease on them can interfere with their ability to power up the device.
  • There are specialized hearing aid dehumidifiers that you can purchase for storing the batteries and devices which will keep moisture out of them and help you to get more hours from the one battery.

Rechargeable Hearing Aid Batteries

There are many technical devices these days that take rechargeable batteries as it offers a number of benefits to the user. Investing in rechargeable batteries means you’re doing less damage to the environment, creating less waste, and saving yourself money by not having to purchase disposable batteries every few months.

However, hearing aids are still somewhat behind with this technology as the use of rechargeable batteries isn’t quite as common as with other gadgets.

There are some brands around that create these batteries to replace the disposable zinc-air ones, but considering the usually low cost of zinc batteries, the need for rechargeable ones isn’t as high as with other devices.

The Future of Hearing Aid Batteries

As people look for ways to make life easier and save themselves money, there’s no doubt that the rechargeable hearing aid trend will continue to grow. With the average hearing aid battery costing around $1 and needing to be changed weekly or monthly, the cost can certainly add up.

Another thing that we can hope for in the future is an easier to change battery that doesn’t require a lot of work, as the act alone can put some people off from it. Although these improvements might sound minor they will mean a lot for the people who rely on using these hearing instruments each day of their life.
