Hearing aids are essential devices that help millions connect with the world around them, but their effectiveness hinges on the batteries that power them. Choosing the right batteries for hearing aids can significantly impact their performance and lifespan. With various battery sizes and types available, knowing which one suits your device is crucial. In this guide, we’ll break down everything you need to know about hearing aid batteries, making the selection process simple and ensuring your device works at its best.
1. Types of Hearing Aid Batteries
Before moving on to the specific factors to consider, it’s essential to understand the available types of batteries for hearing aids. Generally, hearing aids use button-sized disposable zinc-air batteries. These batteries come in four standard sizes, each with its own color coding to help you recognize them quickly. Here’s a breakdown:
- Size 10 (Yellow): These are the smallest batteries and are typically used in very small hearing aids like in-the-ear (ITE) or completely in-canal (CIC) devices.
- Size 312 (Brown): These are common in behind-the-ear (BTE) and some in-the-ear hearing aids. They offer a longer lifespan than size 10 but are still quite compact.
- Size 13 (Orange): Known for lasting longer, these batteries for hearing aids are larger and often used in more powerful models like those for moderate to severe hearing loss.
- Size 675 (Blue): The largest of the hearing aid batteries, these are used in high-power hearing aids, particularly for severe hearing loss.
Each size works with specific hearing aids, so make sure to check the recommendation for your model. Using the wrong size could damage your hearing aid or cause it to malfunction.
2. Disposable vs. Rechargeable Batteries
Traditionally, hearing aids relied on disposable zinc-air batteries. These batteries are widely available and activate once you remove the adhesive tab. Their shelf life is impressive—often up to three years—but their lifespan once in use can range from three to ten days, depending on usage.
However, rechargeable hearing devices are growing in popularity. They are ideal for people who want to avoid changing batteries for hearing aids often. Most rechargeable models use lithium-ion batteries. These batteries can last a full day on one charge and typically last several years before needing replacement.
Both options have their advantages:
- Disposable batteries: Great for those who want flexibility or for people who don’t have access to charging points during the day. You can always carry extra batteries just in case.
- Rechargeable batteries: A great eco-friendly option. If you prefer convenience, simply charging your hearing aids overnight can save you the trouble of changing batteries every few days.
The right choice between disposable and rechargeable depends on your lifestyle. Are you someone who likes to travel or spends lots of time outdoors? Disposable might be the way to go. Are you always near a charging point and prefer less fuss? Rechargeable might suit you better.
3. Battery Life: How Long Will It Last?
Battery life is a key factor to consider when choosing batteries for hearing aids. Several things can influence how long your battery lasts:
- Hearing aid model: Smaller hearing aids usually use smaller batteries, which means they tend to run out faster. Larger, more powerful models often need more power, meaning a larger battery may be necessary.
- Usage time: How often you use your hearing aids will significantly impact battery life. If you’re using them all day, every day, the battery will drain faster than someone who only wears them occasionally.
- Features: Modern hearing aids come with all sorts of features like Bluetooth, noise reduction, and volume adjustments. These extra functions can draw more power from your battery.
As a general rule of thumb, smaller batteries (like size 10) tend to last about three to five days. Size 312 and 13 batteries usually last around seven to ten days, while size 675 batteries for hearing aids can last up to two weeks.
4. Shelf Life and Storage
Believe it or not, hearing aid batteries have a shelf life even when they’re not in use. Zinc-air batteries are activated by air, which means the moment you peel off the sticker, they start losing their charge.
To get the most out of your batteries, it’s important to store them properly.
- Keep them at room temperature: Heat can reduce battery life, so avoid storing them in hot places like near windows or in your car. On the other hand, don’t store them in the refrigerator—a common myth! Cold temperatures can cause condensation, which can damage your batteries.
- Leave the tab on: Don’t peel off the tab until you’re ready to use the batteries for hearing aids. This will keep it fresh until it’s time to power up your device.
- Avoid metal objects: Batteries can short-circuit if they come in contact with metal objects like keys or coins. Keep them in their original packaging until you’re ready to use them.
By storing your batteries correctly, you can ensure that they last as long as possible, saving you both time and money.
5. Knowing When to Change Your Batteries
Knowing when to change batteries for hearing aids can help you avoid sudden power loss and interruptions in your hearing. Most hearing aids will give you a warning beep when the battery is running low. Once you hear this, it’s time to swap out your battery.
Here are a few signs that it’s time to replace your battery:
- Sound quality decreases: You might notice that the sound coming through your hearing aids isn’t as crisp or clear as usual.
- Frequent beeping: Some hearing aids give off a beeping sound when the battery is about to die.
- The device turns off unexpectedly: If your hearing aid shuts off without warning, it could mean that your battery is drained.
It’s always smart to carry spare batteries for hearing aids or have your charger with you to avoid any downtime.
6. Eco-Friendliness and Cost Considerations
The type of battery you choose also affects both the environment and your wallet.
Rechargeable batteries are often considered more eco-friendly since they reduce the number of batteries that end up in landfills. They also save you money in the long run since you don’t need to keep buying new batteries every week.
On the other hand, disposable batteries for hearing aids are initially cheaper and easier to replace in a pinch. However, frequent use means you’ll go through a lot of batteries over time, which can add up.
For the environmentally conscious, rechargeable batteries offer a greener solution, while disposable batteries may be a better option for those who value flexibility and upfront affordability.
Conclusion
Choosing the right batteries for hearing aids might seem like a small detail, but it can make a huge difference in how well your hearing aids perform. By understanding the types of batteries available, comparing the benefits of disposable and rechargeable options, and following proper storage and usage tips, you can ensure you get the most out of your hearing aids. Whether you prefer the flexibility of disposable batteries or the convenience of rechargeable ones, being well-informed will keep your hearing aids powered up and ready to help you navigate the world of sound.
