How long do hearing aid batteries last? This is an important question for users of hearing aids to consider. The lifespan of hearing aid batteries can be crucial when it comes down to purchasing a new device or looking for value for money. Much like many battery-related questions, this one is dependent on many variables. Your device will usually dictate the required battery and there are several considerations to take into account.

Naturally, the more you wear your hearing aids, the quicker the batteries will deplete. Hearing aids belong to a group of high demanding devices and require optimal power consistently. It is only when the device is switched off that power is not used.

All zinc-air hearing aid batteries rely on the air entering the battery to start the reaction that produces power. On unused hearing aid batteries, they will have an adhesive tab on the top to prevent air from entering the battery and starting the reaction. As soon as you remove this tab, the reaction and battery life begin. I can take up to 5 minutes for the hearing aid battery to reach full charge. The battery’s life will continue to deplete, even if not in use.

As a consequence of these various factors, we recommend that you familiarize yourself with your device’s low battery warning notification process. After a while, you will become accustomed to the duration to expect for your particular hearing aid and its typical usage pattern.

Furthermore, you should consider carrying an additional battery set just to be on the safe side.
