What are rechargeable hearing aids?

Today's rechargeable digital hearing aids are much more technologically advanced than they used to be. With simple and reliable charging, rechargeable hearing aids allow you to carry on with your active life without worrying about your hearing aids running out of power.

While many hearing aids come with disposable batteries, hearing aids without batteries – as rechargeable hearing aids are often referred to – are becoming increasingly popular. Rechargeable hearing aids let you enjoy superior sound quality without the need to regularly buy and change hearing aid batteries.

Hearing aids with rechargeable batteries can just be inserted into a recharging unit at night, or when you are not using them. With the battery built into the hearing aid, it means you don’t have to worry about a battery going dead, and no more inconvenient hassles of changing the battery.

The rechargeable option is available in ReSound Receiver-in-Ear (RIE) hearing aids. Sitting comfortably behind the ear, RIE hearing aids have more space for advanced features and extra power, yet they are very discreet due to their small size.

The technology of rechargeable hearing aids

In a world where almost every piece of technology is accompanied by a charger, it’s only natural that hearing aids have become rechargeable too. Just like you would charge your smartphone overnight, the same routine goes for rechargeable digital hearing aids, so you’ll never have to miss a special moment because a battery needs to be changed.

While rechargeable hearing aids have been available for some time, they weren’t popular because of their low power output. Thanks to advancements in hearing aid technology, today’s best rechargeable hearing aids give you power that lasts longer than a full day.

Traditionally, the batteries were produced with Nickel metal hydride (NiMH). Now, the best rechargeable hearing aids use Lithium-Ion or Silver-Zinc battery technology, which has completely changed the performance of rechargeable digital hearing aids.

How a hearing aid charger works?

Chargers for rechargeable hearing aids are typically easy-to-open, hard-cased designs you can place on a table and pack in a bag. Inside the hearing aid chargers are charging bays for the hearing aids and the receivers. Colour coding is often used to show the left and right, so you know which hearing aid to place in which charging bay, e.g. red for right and blue for left. LED lights at different points on the charging case show the power status of the charger and your hearing aids. One glance lets you know if you are fully charged or need a bit longer.

Hearing aid chargers come with a charging cable; one end plugs in the back of the charging case, and the other end plugs into a power outlet. Use only the cable supplied with your hearing aid charger and don’t mix and match with other cables you have at home.

Battery indication

You usually need to charge your hearing aids for around three hours before using them, even if the battery lights indicate that the hearing aids are fully charged. You can charge your rechargeable hearing aids in your charger overnight as you sleep. However, remember to check the product guide of your hearing aids and charger for full, specific instructions.

Here's a general rule of thumb for charging hearing aids:

Red light blinking = less than 10% power remaining

1 green light = >30% charged

2 green lights = >60% charged

3 green lights = >100% charged

Easily clean and care for your charger:

  • Wipe over the outside surface of your hearing aid charger with a dry, clean cloth.

  • Don’t use liquid cleaners.

  • Cotton buds are handy for cleaning the small, inner charging bays.

  • Do this regularly to keep your hearing aid charger in good condition.

  • Grease marks and dust can easily build up during daily wear and tear.

  • Remember to store your charger away from excessive heat – this can include direct sunlight on a very hot day.

The differences between chargers

Innovative recharging technology gives you expanded freedom and flexibility, enabling you to charge your hearing aids anywhere. The choice is often a premium or a standard charger. Both are stylish, portable, and protective cases that power up your hearing aids and are ideal for travelling and storage, but there are subtle differences.
