Every hearing aid is powered by batteries. However, the type of battery varies—some hearing aids use disposable batteries, while others use rechargeable batteries—and both deserve some consideration when you’re thinking about getting hearing aids.
So which is better: hearing aids with disposable batteries or rechargeable hearing aids? It can be a highly personal choice that depends on a number of factors. This guide will help you understand the differences between the two kinds of batteries so you can pick the best hearing aid for your budget and preferences.
Disposable battery-powered hearing aids use small, removable zinc-air or button cell batteries to power the electronic parts of your hearing aid. These electronic parts include the microphone, receiver and internal processing components. The batteries must be replaced regularly for disposable battery-powered hearing aids to keep working—how often depends on the model you have and your usage.
One downside of disposable battery-powered hearing aids is that the batteries must be regularly replaced for the hearing aid to keep working. This means keeping replacement batteries on hand at all times. Fortunately, many hearing aids will give you a “low battery” alert so that you know when it’s time to replace your batteries, before they fully die.
So, how long do disposable hearing aid batteries last? It depends on the brand and how often you use them. However, 10 to 16 days is typical. Maximize the battery life by waiting to remove the sticker until you’re ready to use the battery. Conserve power by leaving the battery door open while you sleep and turning off your hearing aids when not in use.

Rechargeable hearing aids use built-in lithium-ion batteries that don’t need to be replaced. Instead, you set your hearing aids into or onto a charger, similar to your cell phone or tablet. Once the batteries have recharged, you can use your hearing aids again.
