Batteries can last from a couple of days to a couple of weeks. Many factors influence the lifespan of your hearing aid batteries. How long a battery lasts can be affected by its size, the amount of amplification needed for your hearing loss, the amount of time the hearing aid is used, humidity, temperature, and different listening environments.

Always remember to allow the battery to “breathe” when you remove the tab from the battery. You should wait at least one full minute before using the battery in the hearing aid in order for air to completely fill the battery and produce a full charge. Make sure your hands are free from dirt, oil and lotion before handling your battery.
