Lithium-ion rechargeable batteries power smartphones, tablets, laptops, and even various medical devices, including certain hearing aids. Silver-zinc rechargeable batteries for hearing aids generally need to be replaced once a year. As an added bonus, they are completely recyclable, which is important because they don’t last forever. What about safety? Silver-zinc rechargeable batteries are non-toxic and very stable. They can not only be used in hearing aids specifically designed for silver-zinc batteries but also for other models that have been adapted to accept this type of battery. Plus, silver-zinc battery systems are backward compatible. You can even swap in a disposable battery and continue to use your hearing aid if you need to charge your silver-zinc rechargeable hearing aid battery. What if you forget to charge the battery and discover you’re running low in the middle of the day? Silver-zinc hearing aid batteries are removable, so you can be charging one battery while using a different one to power your hearing aids. For starters, they have a high energy density and deliver enough power for 24 hours of continuous use on a single charge. Silver-zinc rechargeable batteries for hearing aids are a newer technology, and they hold a great deal of promise. Generally, rechargeable NiMH hearing aid batteries need to be replaced every year. Another issue is that NiMH batteries have a tendency to lose capacity over time, so the period of time that the battery can power a hearing aid tends to shrink as the battery ages.

Even when fully charged, an NiMH battery is not able to deliver enough power to operate most modern hearing aids for a full day. In fact, NiMH batteries generally cannot match the energy needs of today’s power-hungry digital hearing aids. As a result, they won’t last as long before they need recharging.

Unfortunately, NiMH batteries have a low energy density when compared to popular zinc-air disposable hearing aid batteries. They are often charged while in the hearing aid, so there’s no need for frequent fiddling with tiny batteries and devices. On the positive side, these batteries employ a time-tested technology that has been used in hearing aids for more than a decade. Until fairly recently, most rechargeable batteries for hearing aids were nickel-metal hydride, or NiMH, batteries. Nickel-Metal Hydride Rechargeable Batteries There are currently three kinds of rechargeable batteries for hearing aids available. Can rechargeable batteries deliver this combination? Manufacturers certainly believe so.

They need batteries that are both small and powerful. Today’s hearing aids are incredible feats of engineering that pack a lot of technological features into a petite package, but they require power to perform. Are rechargeable hearing aid batteries a good choice for you?Įxploring Rechargeable Hearing Aid Batteries The battery powering a hearing aid will influence its performance, and there are various batteries to choose from. Using hearing aids to better hear the world around you can improve your quality of life immensely, so it’s no wonder that people who routinely wear these devices want to keep them working smoothly.
