Hearing Aid Batteries
Everything You Need to Know About Hearing Aid Batteries
We keep a supply of batteries for you to purchase in our office. Stop in routinely for fresh batteries. Make sure to check the batteries in your hearing devices often and make sure there is no dirt, wax or debris interfering with the batteries performance. Batteries that are properly charged will make a noise (a squeal) when cupped in your hand or after it has been inserted in your ear, when you cup your hand over the hearing aid it will also make a noise.
A standard “zinc-air” battery lasts anywhere from three to 22 days, depending upon the type of hearing aid, the capacity of the battery, and the amount of hearing aid use throughout each day. The smallest hearing aid batteries, used for 12 to 16 hours per day, may need to be changed every three or four days, while the largest hearing aid batteries used for only a couple hours each day may go several weeks without needing to be changed.
To minimize battery drain, turn off the hearing aid when it’s not in use. Opening the battery door is also an option, and a good way to dry out accumulated moisture. But if the hearing aids won’t be used for an extended period of time (overnight, for instance), removing the battery entirely is the best method.
When storing batteries, keep them at normal room temperature (not refrigerated). Prior to changing batteries, wash your hands thoroughly to remove grease and dirt, which may drain the battery more quickly or dirty the inside of your hearing aid. When the battery dies, it should be removed immediately. A completely discharged battery may swell and become difficult to remove from the small device.
How Do I Change My Batteries?
There are a few ways to know when to change batteries. Some hearing aids will emit a small beeping sound when the battery is low, while some will speak to the user, stating that a change of batteries is needed. Hearing aids that don’t emit warnings typically worsen in sound quality, become distorted, or simply die altogether. The hearing aids may become more quiet before the batteries die — an indication that it’s time to change them.
Note: If a change of batteries does not alleviate this problem, the device may be damaged, and it should be looked at by a hearing care provider.
To insert or replace batteries:
- Open battery door using nail grip.
- Remove old battery (if necessary).
- Remove new battery from package, and pull protective tab from battery. Let the battery rest for 5 minutes before placing battery into compartment.
- Align “+” sign on flat side of battery with “+” sign on battery door.
- When battery is secure, close door.
