Hearing Aid Batteries
Hearing devices can be life-changing, but they can’t help you if the hearing aid batteries are dead. Hearing device users know when they hear that little beeping noise, they’d better have a spare pack of batteries handy.
Hearing aid batteries typically last between 3-7 days, depending on factors like:
- The type and size of hearing device you have
- The type and size of the battery
- The number of hours per day you’re using your device
- The technology level of the device
- The environmental requirements placed upon the hearing devices to process sound
- The shipping and storage of a battery before you purchase it
Luckily, there are several best practices to keep hearing aid batteries well-maintained and help them last as long as possible.
- Always use your oldest package of hearing aid batteries first.
Although hearing aid batteries can be stored for quite a while, the longer the batteries sit in storage, the shorter their life will be. If you always use the oldest package first, your spare batteries will never get too old.
- Store extra hearing device batteries in a dry, room temperature place. NEVER refrigerate them!
Extreme temperatures—both hot and cold—and high humidity levels are not good for the life of your hearing device batteries.
- Don’t remove the plastic tab from each pack’s battery until you’re ready to use it.
This plastic tab keeps the battery fresh while it’s in storage, and as soon as you take it off, the battery is activated. It will start to lose its “juice” once removed and replacing the sticker won’t save the battery.
- Wash your hands before replacing your hearing aid battery.
Grease and dirt on your hands can be transferred to the battery, which could affect the lifespan of the battery.
- Let the battery sit out for five full minutes after you remove the plastic tab.
When you take the plastic tab off, the zinc in the battery mixes with the air to power it up. It is unclear why, but recent research has shown that if you wait five whole minutes, you can extend the battery’s life by as much as 2-3 days.
- Leave the battery compartment open when you’re not using your devices.
Whenever you’re not using your hearing aid, turn it off, put it somewhere safe and dry (don’t leave it on the bathroom counter while you shower!), and leave the battery door open. This allows excess moisture to escape and reduces the drain on the battery. It also keeps the battery from corroding, which is not good for the hearing devices.
- Remove the batteries entirely if you won’t be using the device for an extended period of time.
This also helps to avoid corrosion and damage from trapped moisture.
