Rechargeable vs. Battery-Powered Hearing Aids: which is better?

Advancements in hearing technology have introduced a range of options to suit varying individual needs. One of the most significant decisions when selecting a hearing aid is whether to opt for a rechargeable model or one powered by disposable batteries. Each solution offers distinct advantages and potential limitations.

A comprehensive comparison between Rechargeable and Battery hearing aids

Disposable Battery Hearing Aids have been the standard for many years and use zinc-air batteries, typically in sizes 10, 312, 13, or 675. These batteries are readily available and easy to replace, with lifespans ranging from a few days to a couple of weeks, depending on usage and device type. Many users appreciate the independence of carrying spare batteries and not having to rely on charging equipment—especially helpful in remote areas or while traveling.

On the other hand, Rechargeable Hearing Aids offer modern convenience and environmental benefits. Most current models use lithium-ion batteries, which can be recharged overnight and last a full day on a single charge. They eliminate the need to handle small batteries, making them especially beneficial for those with dexterity challenges. Over time, rechargeable devices can also be more cost-effective and eco-friendly, reducing the need for frequent battery purchases and disposal.

While disposable batteries may offer more flexibility in certain situations, rechargeable hearing aids are increasingly popular for their simplicity and user-friendliness. At Amplifon Canada, our hearing care professionals can help you explore both options and choose the one that best fits your hearing needs and lifestyle.

Understanding Rechargeable Hearing Aids

Rechargeable hearing aids represent the latest in hearing technology. Much like smartphones and other personal electronics, these devices can be charged overnight using a dedicated charging station. Most models are designed to last a full day on a single charge, even with advanced features such as Bluetooth connectivity enabled.

These hearing aids are especially beneficial for individuals seeking a more environmentally responsible and user-friendly option. The elimination of disposable batteries simplifies daily use and reduces environmental waste over time.

Rechargeable hearing aid batteries

Rechargeable hearing aid batteries have transformed the way users experience and manage their hearing devices. Powered primarily by advanced lithium-ion technology, these batteries offer a full day of use on a single overnight charge—including streaming from smartphones and other Bluetooth devices. This makes them incredibly convenient for daily life, eliminating the hassle of frequent battery changes. They're also ideal for users with limited dexterity, since there's no need to handle or replace tiny batteries. In addition to user-friendliness, rechargeable batteries are more sustainable and environmentally conscious, reducing battery waste over time. With robust power and easy charging stations, rechargeable hearing aids provide a modern solution that supports both lifestyle needs and long-term value.

Advantage of rechargeable hearing aids

  • Ease of Use: No need to frequently handle or replace small batteries.
  • Eco-Friendly: Significantly reduces battery waste and environmental impact.
  • Cost-Effective in the Long Term: Though the initial investment may be higher, the absence of ongoing battery purchases leads to savings over time.
  • Reliable Performance: Delivers consistent power throughout the day with proper overnight charging.

Considerations

  • Devices must be charged regularly to maintain functionality.
  • Rechargeable batteries typically require replacement every few years.

Battery-Powered Hearing Aids

Traditional battery-powered hearing aids use disposable zinc-air batteries, which are activated when exposed to air. Depending on usage and the specific device, these batteries generally last between 3 and 10 days.

For individuals who travel frequently or do not have regular access to charging facilities, battery-powered devices remain a highly practical solution. Having spare batteries on hand ensures continued use without reliance on electrical outlets.

Benefits of Battery-Powered Hearing Aids

  • Immediate Use: Fresh batteries provide instant power without waiting for a charge.
  • Convenient for Travel: No charging equipment is necessary.
  • Lower Initial Investment: Typically more affordable at the time of purchase.

Considerations

  • Regular replacement of batteries incurs ongoing costs.
  • Battery disposal contributes to environmental waste.
  • Small battery handling can be challenging for individuals with reduced dexterity or vision.
