Rechargeable Hearing Aids

Rechargeable Hearing Aids

As technology evolves, hearing aids get more efficient, and easy to use. There is a huge gap between the hearing aids of today and the ones your parents or grandparents used to use. Alongside Bluetooth technology, one of the most exciting recent developments is rechargeable technology.

The last redoubt of disposable batteries

For a long time, hearing aids have relied solely on disposable zinc-air batteries. It’s easy to see why, as they are cheap, simple to replace and widely available. But with rechargeable technology making headway in other consumer devices such as smartphones, e-readers and tablets, people started to demand the same convenience with their hearing aids.

Successive iterations of rechargeable technology were subsequently developed, each improving on the last. But the latest development, called lithium-ion technology, may be the best yet. This game changing technology is the first to achieve a full-day’s worth of power on one charge.  There are many reasons to take advantage of lithium-ion rechargeable hearing technology.

Why use rechargeable hearing aids?

1. More convenient

You simply place the hearing aids in the charge dock overnight to charge and your hearing devices are primed and ready to go in the morning. Most models take advantage of inductive charging, which makes it even easier to charge your hearing aids before bed.

You don't have to remember to buy batteries or carry spares, and your battery won't let you down at the most inopportune times.

2. Environment

Rechargeable batteries also contribute to saving the environment. Batteries are fairly difficult to recycle and people don't usually make sure that they are carefully disposed of. Rechargeable batteries must of course also be carefully disposed of, but this is much less often than the average hearing aid battery!

Also, corrosive materials and heavy metals are commonly found in many hearing aid batteries because of the battery production process. The casing can disintegrate if the batteries are not properly disposed of, causing these harmful substances to leak into the environment. This can lead to soil and water contamination and can negatively affect animals as well as humans.

3. Better for the less dextrous

You don't have to mess with small batteries every few days with rechargeable batteries. If someone has visual or dexterity issues, the small size of conventional disposable hearing aid batteries and hearing aids themselves can be tricky to replace.

4. No need to compromise on features

Batteries did not need to be replaced often with older hearing aid models because they had no wireless and digital functionality. But traditional zinc air batteries do not last as long as they once did with newer hearing aid models, because of today's more advanced technology. You could have to switch the batteries a few times a week, instead of once a month.

But lithium-ion rechargeable batteries can keep up with all the power needs of today's digital technology while maintaining enough charge for an entire day of hearing.

If you ever find yourself forgetting to charge them, fear not – you can get five or six hours of charge by plugging in for just thirty minutes.

The Pure Charge & Go technology from Signia use take advantage of a high-capacity lithium-ion cell alongside innovative wireless charging technology. Wireless charging means that consumers do not need to care about the precise positioning of their hearing aids on the recharge port because charging doesn't rely on electrical contacts.

This means you could stream 12 hours of content in one day, and still have enough charge to see you through the entire day.

The sound quality when listening to music also superlative. Studies indicate that compared with other premium hearing aids, ReSound LiNX Quattro is favoured for 95% of the time for streaming music.
