Much like traditional hearing aids, rechargeable hearing aids amplify certain sounds and mute others to enhance the hearing experience of people with varying levels of hearing loss. These small, electronic devices often use lithium-ion batteries and come in several types, including behind-the-ear (BTE), in-the-ear (ITE), in-the-canal (ITC) and receiver-in-canal (RIC) hearing aids.
Unlike hearing aids powered by disposable batteries, rechargeable hearing aids contain batteries that can be recharged overnight, meaning wearers don’t have to remove and replace their devices’ batteries on a regular basis. How long a battery charge lasts can depend on the way someone uses the hearing aid. For example, a hearing aid may offer up to 30 hours of use on a single charge but only deliver 24 hours of charge when the device is used for streaming activities, which tend to require more energy. Rechargeable hearing aid batteries are usually charged overnight using a charging unit, reaching a full charge in several hours.
How Do Rechargeable Hearing Aids Work?
Similar to hearing aids with disposable batteries, rechargeable hearing aids amplify sounds in a three-part process during which a microphone picks up sound and converts it into a digital signal that is then amplified and carried to the ear through a speaker. Rechargeable hearing aids, however, contain a built-in battery that doesn’t need to be removed. At the end of each day (or whenever the hearing aid battery is low), rechargeable hearing aids are placed on a charging unit to charge overnight or within a matter of hours.
How Do You Charge a Rechargeable Hearing Aid?
Rechargeable hearing aids come with charging cases. While these ports are often included with the purchase of hearing aids, some companies offer additional styles that can be purchased separately.
To charge a rechargeable hearing aid, simply ensure the charging port is powered on and place the hearing aids in the charging port. Leave the hearing aids in the charging port for as long as instructed by the manufacturer to obtain a full charge. The length of time it takes to fully charge a hearing aid depends on the manufacturer, hearing aid model and battery size. Rechargeable hearing aids can be charged at any time of day or night, though it’s important to charge them during a time when you don’t need to use them, such as while asleep.
