Common Questions About Hearing Aid Batteries
What are hearing aid batteries made of?
Hearing aid batteries are most commonly made with zinc-air chemistry, including GP hearing aid batteries.
How long do hearing aid batteries last?
How long a hearing aid battery will last depends on its size, styles and capacity. Typically, physically larger hearing aid batteries will last longer than smaller ones as they require higher power.
At GP, our batteries deliver 50% more power* than the industry average, giving you peace of mind for long journeys knowing you won’t run out of power. Additionally, our hearing aid batteries have a shelf life of up to 4 years, so you can stock up on batteries as the power is reserved within the shelf life. You can stock up without worries.
How to make a hearing aid battery last longer?
A hearing aid battery begins to activate as soon as the plastic tab covering it is removed and the battery is in contact with air. Removing the tab allows air to enter the small holes covered by the plastic tab. Once this occurs, the battery is active and the power will start draining. This is why you should open a new tab only when you intend to place and use the battery in your hearing aid. Allow around one minute for the battery to come in contact with air as it needs to achieve full power. This will help to significantly expand its life.
Are hearing aid batteries dangerous?
Swallowing hearing aid batteries is a hazard you need to be mindful of, especially around children and inquisitive pets. Due to the small size of the battery, they also pose a choking hazard to children and adults; they may be mistaken for sweets or a pill. It is best to keep hearing aid batteries away from children and remain diligent.
