What To Look For In Hearing Aid Batteries

Buyers tips for hearing aid batteries.

Hearing aids are amazing devices. Millions of people around the world would not be able to enjoy their lives fully without them, and the technology is only getting better and better.  Decades ago, the options for someone with hearing loss were minimal to say the least.

While hearing aids were around back then, there was not the same amount of variety and quality that we have today. But no matter what type of hearing aid you get, you will have to deal with hearing aid batteries.



Because there are so many different types and sizes of hearing aids, finding the proper hearing aid batteries can be a chore to some people. In many cases, it can be easy to lose track of which batteries go with which hearing aid.

When looking at them side by side, it can be hard to tell the difference between a battery for one type of hearing aid and a battery for another. And even if you know exactly what kind of hearing aid batteries you need, you still have to decide on the brand of battery that will best suit you.

Just like normal, standard size batteries, telling the difference between the numerous batteries for hearing aids is not always easy. In most cases, it depends on your own personal preference, but certain batteries are better than others. To be sure that your hearing aids are working to their optimum capabilities, it is important to get the right hearing aid batteries. And unless you know what to look for, this can be hard.

While the price of batteries for a hearing aid are not always indicative of the quality, in many cases you get what you pay for. If you purchase the cheapest batteries that you can find, you are most likely going to have to purchase new ones fairly shortly. You want to pick a brand of batteries that is going to give you the most amount of time with your hearing aids, for the least amount of money.

But before you get to that point, you need to be able to tell what size you need. Within the past decade, the industry developed a standard size range for batteries. In order to help consumers better remember their battery size, a color code system was developed and put into place. Each color is attributed to a different size.



Once you pull off the tab on the back of a battery, it becomes activated. The colors and numbers for each specific size have been standardized, so you do not have to worry about different brands switching up the colors. If your current battery brand has the color red, so will all of the corresponding batteries for the other brands.

On some occasions, you will be able to see various letters on the battery as well, but those are not something that you need to be concerned about. As long as you are able to remember the size by looking at the color, you will always have the proper hearing aid batteries for your specific model.

If you ever forget what color your batteries are supposed to be, check with your hearing health care professional. They will have a chart that you can look at which will tell you exactly what color you need.

The length of time that hearing aid batteries will last depends not only on the brand, but also the particular type of hearing aids that you are using. If your hearing aid requires more power, the battery will obviously run out a bit faster. Analog hearing aids do not require as much power as digital hearing aids, so their batteries can last longer.

The reason is because digital hearing aids are much more complex, and more complex usually means that they take more energy to power. Usually, hearing aid batteries will last anywhere from five to seven days.

If you have been noticing that your batteries wear out faster than that, you should have your hearing aids check by a professional, as this could be a sign that they are not performing properly. Hearing professionals can check the battery contacts in the hearing aids, and also test battery drain to see if there is some sort of issue causing a malfunction. In cases where there is something wrong with the hearing aids, you can have them sent in for repair.

Hearing aid batteries can also run out more quickly than they should if you leave them in places where they will be in hot temperatures. Heat can make the activation stickers on the back of hearing aid batteries peel off, which would cause them to start releasing energy even when you’re not using them. And since the stickers will go back onto the battery as soon as it gets cool again, you will probably never notice. So it is best not to keep them in places where they will be able the heat up, like a car for example.

Most of the hearing aid batteries on the market work by mixing zinc with oxygen. These are known as “Zinc Air” batteries. When you take the tab off of a hearing aid battery, it immediately becomes active. Even if you put the tab back on, the damage is already done.

As soon as that tab is peeled the first time, there is no going back. Keep the tabs on until the last minute when you are ready to use them. As soon as the batteries die, do not mix them back with new ones, as you could get confused by doing that.

If you are careful to keep the tabs on the hearing aid batteries and keep them out of hot environments, your batteries can sit on the shelf for about three years before going bad. After three years, you risk poor battery performance. As long as you take proper care of your hearing aid batteries, you should never have a problem.

Talk to you hearing care professional and ask them for advice on what batteries they would suggest for your specific brand. The process of choosing a battery is fairly simple, and you should not have to lose any sleep over it.
