Hearing aids are sophisticated devices that require correct handling. Knowing the proper shutdown procedure extends battery life and ensures device longevity. Turning off the device prevents unnecessary battery drain and avoids the loud whistling known as feedback, which often occurs when the microphone is covered during removal. Learning the specific method for your hearing aid type contributes significantly to effective device care.
Turning Off Aids with Disposable Batteries
Hearing aids that rely on disposable zinc-air batteries typically use a mechanical method for powering down. This design physically breaks the electrical circuit to conserve the battery’s charge. The primary technique for turning off these devices is opening the battery door fully until the device is completely deactivated.
The battery door acts as the power switch. Partially opening it ensures the battery terminals are no longer in contact with the hearing aid’s internal components. For behind-the-ear (BTE) and receiver-in-canal (RIC) styles, this means flipping the compartment open until it clicks into its most open position. Leaving the door open overnight also allows air to circulate inside the compartment, which helps prevent moisture buildup.
Some older or less common models may feature a dedicated physical switch or lever, often positioned discreetly on the body of the aid. This is especially true for in-the-ear (ITE) or completely-in-canal (CIC) devices. If opening the battery door does not power down the device, locate the small, tactile switch and push it momentarily to shut down the electronics. Ensure the door is opened slightly, even on models with a switch, to allow the battery to “breathe” and avoid drain.
Powering Down Rechargeable Devices
Modern rechargeable hearing aids utilize internal batteries, meaning their shutdown process is electronic or automated rather than mechanical. The most common method is placing the aid into its charging cradle or case. Most contemporary models automatically power down the moment they make contact with the charging ports, beginning the charging process.
If you need to turn off a rechargeable hearing aid without placing it in the charger, a dedicated push button or rocker switch is the alternative. This requires a sustained press for three to five seconds until the device plays descending tones or an indicator light turns off. The longer press distinguishes the power-down command from a simple program change or volume adjustment, which requires only a short tap.
Another method involves using a linked smartphone application, which is common with Bluetooth-enabled devices. While the app’s primary function is adjusting settings, some manufacturers include a remote power-off function within the digital interface. Using the app initiates an electronic shutdown command to the hearing aid, which is a discreet option.
Proper Handling After Shutdown
Once a hearing aid is powered off, the focus shifts to storage and maintenance to protect the internal electronics. The primary enemies of hearing aids are moisture, heat, and physical damage, so proper storage is important for longevity. Hearing aids should be stored in a cool, dry location, ideally in their original case or a specialized drying unit. Never leave them in a bathroom, kitchen, or car where temperature and humidity fluctuate widely.
Using a dehumidifier or a dry box is recommended. These devices either contain desiccant material or use gentle heat and UV light to draw out moisture accumulated from perspiration or humidity. This nightly drying routine prevents internal corrosion and helps maintain the integrity of the micro-components. Before placing the aids in their storage case, a quick cleaning is beneficial.
Cleaning involves gently wiping the exterior shell with a soft, dry cloth. Use a small brush or pick to clear visible wax or debris from the microphone and sound ports. If a device uses disposable batteries and will not be worn for several weeks, remove the batteries entirely to prevent potential leakage or corrosion of the battery contacts. Keep the powered-down aids out of reach of children and pets, as the small size presents a safety hazard.
