What are the Pros & Cons of Rechargeable Hearing Aids?

Rechargeable hearing aids have surged in popularity recently, particularly with the introduction of the latest wave of the hearing aids from leading manufacturers.

Rechargeable hearing aids have been around for a long time, however, they were not overly popular because of power output. As new features were added, such as streaming, usage got even worse.

The New Generation of Rechargeable Hearing Aids

A new generation of rechargeable battery technologies has arrived and it promises to make life easier. Two new rechargeable hearing aid technologies arrived on the market in 2016, Lithium-Ion and Silver-Zinc. Both of these technologies offer excellent usage and convenience with one-charge-per-day-standard, but each have different benefits and limitations.

Lithium-Ion Rechargeable Hearing Aids

Lithium-ion hearing aids have sealed, integrated power pack systems. Sealing the battery in the body of the hearing aid means that it is protected from mishandling, which is great for safety, however, sealing it in the case also means that it cannot be replaced by the user.

Lithium-ion has a life expectancy of between four and five years, which means the battery pack will have to be replaced after four or five years because it will not be delivering what it should. To do this, the hearing aids will likely have to be sent back to the manufacturer and there may be a cost attached for out of warranty repairs.

Silver-Zinc Rechargeable Hearing Aids

Like the Lithium-Ion systems, Silver-Zinc batteries provide power for a day of use. However, Silver-Zinc rechargeable systems are not integrated and not sealed into the hearing aid, which means if you forget to recharge your hearing aid, you can simply slip in a disposable battery. In addition, Silver-Zinc is more stable than Lithium-Ion - it won't explode when damaged.

Some manufacturers, such as Unitron, have made their Silver-Zinc rechargeable hearing aid system backward compatible. If you currently own a Moxi Fit, you can buy the kit and make your hearing aids rechargeable.
