Hearing Aid Batteries
What is Zinc Air technology?
Unlike other batteries, zinc-air cells contain no toxic compounds and are neither highly reactive nor flammable. Zinc air batteries generate power when oxygen from the air comes in contact with the ingredients inside the battery canister. Traditional household batteries must house all their active ingredients inside the battery canister. Thanks to their use of air as an ingredient, zinc air batteries can be very small and still very powerful. Battery performance can be hampered if ambient air is too dry or too humid. We've chosen VARTA batteries because their technology and manufacturing materials and methods help ensure maximum performance in any environment.
Why do hearing aid batteries have tabs?
Hearing aid batteries use air as an energy source. The tab seals the air holes on the top of the battery. Once the tab is removed, it takes approximately ten seconds before the hearing aid battery is activated and the hearing aid battery door can be closed.
Please do not remove the tab before you are ready use it. The battery will start powering up (some call it “airing up”) a soon as air enters the holes. Reattaching the tab will not prolong battery life.
What do the different battery sizes (10, 13, 312, 675) and color codes (yellow, orange, brown, blue) mean?
Hearing aid batteries are offered in four different sizes: 10, 13, 312 & 675. They are color-coded for easy identification:
- Size 10 – Yellow
- Size 13 – Orange
- Size 312 – Brown
- Size 675 – Blue
What battery size should I choose?
Similar to household batteries, the type of device determines the battery size you need. Each hearing device specifies a battery type. If you are unsure which battery your device uses, ask the staff where you purchased the device or check with the device manufacturer.
What does Mercury-Free mean?
Mercury-free means the batteries do not contain mercury, a substance that is not considered environmentally friendly.
What makes power one batteries Wireless Approved?
International battery testing standards include a specific test for Wireless. That’s because wireless functionality increases demand for battery power. Wireless capability enables two hearing aids to coordinate sound processing together and in real time, for better sound quality. Wireless also enables connection to Bluetooth or external microphone (i.e. FM system) in a classroom or public space. With power one batteries, you can be assured of maximum performance whether using wireless or standard hearing devices.
How long should I expect my batteries to last?
The life of any individual hearing aid battery will vary based on many different factors and can change as the situation changes. Here are some examples of the factors that affect battery life: type and functionality of device, length of time the device is used per day, whether or not you use wireless functions or stream media, ambient noise level, the level of amplification, environmental conditions such as temperature and humidity.
What is the best way to prolong battery life?
- Don’t remove tab until you are ready to use them. Once tab is removed, air enters the holes and activates the zinc.
- Store at room temperature.
- Leave the battery door open or remove the batteries from the device if not being used for an extended period of time.
- If not using the hearing aid, turn it off and open the battery door. This minimizes drain and blocks corrosion.
- Place your hearing device in a dehumidifier overnight.
- Wash your hands before changing batteries. Dirt and oil can block the battery air holes.
Do hearing aid batteries leak?
Yes, it is possible for a hearing aid battery to leak. With power one batteries, leaking is very rare.
Do hearing aid batteries expand?
A hearing aid battery may expand if the discharged battery is left in the hearing aid too long after it has expired. It may also expand due to extremely high humidity.
How should hearing aid batteries be stored?
Store your hearing aid batteries at between 50 to 85 degrees Fahrenheit – preferably at room temperature between 65 to 75 degrees. Don’t carry loose batteries in your purse or pocket, as contact with metal objects such as keys or coins may cause damage.
Should hearing aid batteries be stored in the refrigerator?
No. The condensation that develops from the refrigerator increases risk of corrosion and other harmful effects.
How do I dispose of hearing aid batteries?
Most curbside recycling programs are great for recycling power one packaging. Batteries can be recycled through local recycling centers and electronics retailers. You can search for participating retailers at Call2Recycle. Many hearing health professionals offer recycling containers at their office where you can drop off batteries. And, you can always send them back to Akoio for recycling. Please see the contact page for our address.
