Hearing Aid Batteries — What You Need to Know
Did you know that even subtle changes in your hearing aids’ power could affect their performance? They need a steady power supply in order to ensure consistency, clarity, and volume control. What kind of batteries you’ll use depends on the size and power requirements of your hearing aid.
As with all technology, the battery power can be maximized by turning off the device when not in use. Leaving the battery door open is also an option and a good way to dry out any moisture. Taking your batteries out is your best bet when they are not in use for a long period of time (like overnight).
- Keep extra batteries at a normal room temperature,
- Wash your hands before changing batteries to remove grease and dirt that could hinder their performance.
- Remove dead batteries immediately; otherwise they could swell, making them harder to remove.
How Do I Change My Batteries?
Ask your audiologist how you can tell when it’s time for a new battery. Some devices will actually speak to you while others will beep to alert you that your battery needs changing. Please note that if a change of batteries does not stop your devices from beeping, they may be damaged and should be looked at by your audiologist.
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 five minutes before placing battery into compartment.
- Align “+” sign on flat side of battery with “+” sign on battery door.
- When battery is secure, close door.
Different Types of Batteries
There are four main sizes of batteries, each with a specific color-coded package. The battery size you need is almost always based on the size and style of your hearing aid.
- Size 10 (yellow)
- Size 13 (orange)
- Size 312 (brown)
- Size 675 (blue)
Standard hearing aid batteries are activated when exposed to air, so make sure to keep them sealed before you need to use them. And of course, don’t buy batteries if the seal is broken.
- When you remove the tab, it will take about five minutes before the battery is activated and the battery compartment can be closed.
- Do not force the battery door shut or open too far.
- Dispose of used batteries immediately.
- Look for hearing aid cleaning tools that have magnets; this helps get the battery out with ease.
