Ask An Audiologist: What are the alternatives for replacing a hearing aid’s battery?
What are the alternatives for replacing a hearing aid’s battery?
As society demands for smaller and more discreet hearing aids, manufacturers often are challenged with making the batteries ever smaller to shrink the size of the hearing aid. This has two consequences:
- the batteries need to be changed more often due to smaller capacity and
- the smaller sizes make them more difficult to handle, especially if your fingers are no longer as nimble as before (an issue we often see in elderly patients!).
Recently, rechargeable battery technology has become smaller, lighter, and more reliable than before, bringing a new alternative power source for us. Such batteries are everywhere, from our phones to cars as well as hearing aids which gives wearers a new experience with devices that are much easier to handle.
There are two different types of rechargeable battery available in hearing aids: Z-power and Lithium ion (Li-Ion) technology.
Z-power batteries look similar to traditional batteries, just that they are rechargeable. These batteries need to be charged daily with a contact charger and are recommended to be changed annually.
Li-Ion powered hearing aids are the latest innovation! These hearing aids run on batteries which are long lasting and can be charged easily by inductive charging (no contact points). Signia’s products such as Pure Charge&Go, Motion Charge&Go, as well as Styletto Connect are all built on li-ion technology and are ideal for consumers who may otherwise have difficulties in changing batteries!
In addition, hearing aid chargers have also become more efficient and reliable. Recharging Signia hearing aids can be as short as 30 minutes (fast charge) or a few hours for a complete charge. Styletto Connect even comes with its own portable charging case which allows you to take power with you wherever you go!
