Rechargeable hearing aids are a sought-after feature in OTC hearing aids because they eliminate the inconvenience of replacing disposable batteries. No more carrying spare hearing aid batteries or scrambling to find a replacement when you run out. Other added features, such as audio streaming for hearing aids, can drain the battery more quickly, which is not always ideal for replaceable 312 batteries (typically made from zinc-air). However, rechargeable lithium-ion batteries— the preferred rechargeable option for hearing aids— are more than capable of handling extended use.
What are rechargeable hearing aids?
Rechargeable hearing aids, as the name suggests, are devices with rechargeable internal batteries that are fixed inside the hearing aid. These batteries are non-removable and typically charge directly through the hearing aid. Rechargeable hearing aids mostly use lithium-ion batteries (such as those in Go Hearing products) due to their compact size, powerful output, and long lifespan. Their small size is particularly beneficial for inside-the-ear (ITE) hearing aids, as they provide necessary power while keeping the device slim enough to fit comfortably inside the ear. As with all new technology, rechargeable hearing aid battery technology comes with a few drawbacks. Here are the pros and cons of rechargeable hearing aid batteries to help you decide whether they are the right fit for you.
Pros of rechargeable hearing aids
- Convenience: The most significant advantage of rechargeable hearing aids is convenience. You no longer have to struggle with tiny batteries; simply plug them in overnight, like you would with your smartphone.
- Ideal for those with dexterity or vision issues: No need to handle small batteries or worry about inserting them correctly.
- Peace of mind: Rechargeable hearing aids typically provide up to 20 hours of use after one full charge, eliminating the risk of running out of battery at inconvenient times.
- No more spare batteries: You won’t have to keep spare batteries on hand, which often get misplaced or lost.
- Safety: Rechargeable batteries reduce the number of small parts that children or pets may accidentally get their hands on.
- Long-term savings: Over time, rechargeable batteries may be more cost-effective than buying new disposable batteries every few weeks. While the initial cost of hearing aids with rechargeable batteries may be higher, lithium-ion batteries can last up to five years—much longer than disposable batteries (which generally need replacement every 6-12 months).
- Environmental benefit: Lithium-ion batteries result in fewer batteries being thrown away, which is better for the environment.
- Improved protection: Rechargeable hearing aids with lithium-ion batteries have a completely sealed system, reducing the risk of damage from moisture or dust.
- Built-in dehumidifier: Certain hearing aid brands include a dehumidifier with the charger, helping to remove unwanted moisture while the hearing aids charge.
Cons of rechargeable hearing aids
- Power outages: If you experience frequent electricity outages or go somewhere with a limited power supply (like a camping trip), you won’t be able to charge your hearing aids. However, some manufacturers offer portable chargers that can last for a few days without an electrical outlet.
- Traveling challenges: When traveling, it’s crucial to remember to bring the charger with you. Without it, your hearing aids will be unusable, unlike traditional batteries that you can easily purchase at a pharmacy.
- Non-removable battery: Since the battery is contained within the hearing aid and cannot be removed, you won’t be able to use the device if the battery malfunctions until it’s repaired. With non-rechargeable batteries, you can simply replace them on your own.
- Recharge time: If your battery runs out during the day, you'll need to wait for it to recharge (a top-up recharge usually takes about 30 minutes). This is less convenient than just swapping out a disposable battery. Streaming audio for long periods can cause this issue to arise more often.
- No built-in dehumidifier: Not all chargers include a dehumidifier, so your hearing aids may be at risk of moisture damage if you don’t properly balance charging time with dehumidifying.
Are rechargeable hearing aids worth it?
Ultimately, rechargeable hearing aids may not necessarily save you money, but the convenience, ease of use, and environmental benefits are significant advantages. Like all new technology, it might seem intimidating at first, especially if you’re used to disposable batteries. But much like smartphones and fitness trackers, rechargeable hearing aid batteries are here to stay. Soon, you might wonder how you ever managed without them.
