If the hearing aid loses power or breaks at an inconvenient moment, it may be a very unpleasant experience for the user as well as their family and friends, particularly if it happens away from home. When someone’s batteries suddenly die during a party, wedding, or a family backyard barbeque gathering it may be frustrating to the user.
Hearing aid users are well aware that their devices’ batteries must be dependable and functioning at peak levels to provide the best performance and sound management. They probably also know that batteries might die suddenly, so it’s smart to always have a spare set with you.
How long the hearing aid batteries will last depends on several factors, including the battery’s size and freshness, the hearing aid’s design, and the wearer’s surroundings. Let’s look at some of these factors that might affect your hearing aid’s battery life.
Size of the Battery
Hearing aid batteries are available in a variety of types and sizes. How much power may be stored in a single battery cell is proportional to the battery’s overall size. Most of the time, the lifespan of a hearing aid battery increases with its size, the bigger the battery, the longer it lasts. The size of the battery you need is determined by the battery your hearing aid accepts.
The Condition of the Battery
In the same way as most other types of batteries, a zinc-air battery will eventually lose its charge if it is not used. When the tab is in its proper location, a hearing aid battery will lose its charge at a rate of less than 10% each year. To get the most out of your batteries, it is best to buy them in smaller amounts rather than in bulk.
Hearing Loss Severity
The amount of energy used by your hearing aid might vary depending on the extent of your hearing loss. This is a major reason why it may be so difficult to estimate the battery life of a certain device; it all relies on the user.
As the features of your hearing aid get more complex, you’ll need a stronger battery. Bluetooth, wireless streaming, and noise cancellation are just some of the wireless options that can be found in modern electronic devices. A higher current is required to power any of these components in combination resulting in them draining your battery quicker.
Your Current Surroundings
Humidity, temperature, and altitude may all affect how long the battery in your hearing aid lasts. Air that is too dry or too wet might reduce the life of your batteries. Batteries lose capacity in dry environments, while their life is shortened by condensation in humid environments.
Just as how the temperature has a direct effect on the functioning of the hearing aid, it also affects the battery. Between 20 and 50 degrees is ideal for battery performance.
High-altitude regions may have lower oxygen levels than those closer to sea level. This might make it difficult for a hearing aid battery to provide enough power for the device to function properly.
How to Extend the Life of Your Hearing Aid’s Battery
If you’re like the vast majority of people, you’d prefer your hearing aid battery to last as long as possible. Here are some suggestions to help your battery last longer:
For Three to Five Minutes, Let the Battery Breathe
The hearing aid battery should be allowed to rest for three to five minutes after the tab is removed before being inserted. This “activation” time allows air into the battery, which sparks its parts into life.
Keep Your Hearing Aid Dry Using a Dehumidifier
A dehumidifier designed for use with hearing aids may help keep the device and its battery dry. This will allow for more efficient use of battery life. Inside the dehumidifier, your hearing aids will be protected from moisture and dust.
Consider Purchasing a Rechargeable Hearing Aid
Currently, rechargeable hearing aids are only entering the marketplace. Hearing aids with rechargeable batteries may be charged at night and used all day long. However, rechargeable batteries need to be replaced every year. If you are interested in learning more about the new technology, talk to your hearing healthcare specialist.
Though today’s hearing aid batteries have been improved considerably, a finite limit will likely still exist for how long they can power the device before needing replacement or charging. But improved designs and longer-lasting batteries might help stretch the battery life of modern hearing aids to days, or perhaps even weeks, before their power runs out, making it an even more convenient and hassle-free choice for those who use it.
