Rechargeable Hearings: The Pros and Cons

Posted: July 18 2019

With all of the major advancements in technology these days, you might be wondering about rechargeable hearing aids versus traditional, battery-operated hearing aids.  We have created a list of pros and cons to help patients decide which choice is right for their lifestyle.  

1) You do not have to change your batteries once or twice per week.
2) There are no small battery doors and battery cells to handle, making it easier for individuals to use, especially those with dexterity or visual issues. 
3) You do not have to carry extra batteries with you at all times.
4) Charging your hearing aids is simple and easy. 
5) Rechargeable hearing aids are typically more cost-efficient and environmentally friendly than traditional disposable zinc-air batteries.
6) A rechargeable hearing aid will last a full day so you won't run out of power during the middle of an important meeting or event. 
7) Lithium-ion rechargeable hearing aids have proven to be more efficient and robust when operating in colder temperatures.

1) Because a lot of rechargeable hearing aids use built-in lithium ion batteries, you cannot change the battery yourself if the device stops functioning - it must be sent away to the manufacturer for repair.
2) Rechargeable hearing aids cost slightly more to purchase than traditional disposable battery operated hearing aids.
3) When traveling, you have to carry your charger with you, otherwise you will only have one day's use for the entire trip.
4) Some rechargeable hearing aids use silver-zinc batteries, which can be used interchangeably with a traditional hearing aid battery door.  However, this can make them more susceptible to issues with moisture. In addition, these silver-zinc batteries do have to be changed every 6 months to a year to provide optimal functioning.
5) If you use a lot of wireless streaming such as television or phone, your rechargeable hearing aids may not last a full day.
6) Some rechargeable hearing aids are much larger in size than traditional hearing aids in order to account for the lithium-ion technology.
7) Lithium-ion batteries typically will last 4-5 years after which time they may need to be replaced.
