Hearing aid batteries play a critical role in ensuring the proper functioning of your hearing devices. Here’s a guide on hearing aid batteries, covering various aspects from types to maintenance:
- Types of Hearing Aid Batteries:
Zinc-Air Batteries: Most common for hearing aids, available in sizes 10, 13, 312, and 675.
Silver-Zinc Batteries: Rechargeable batteries becoming more popular for their eco-friendliness.
Lithium Batteries: Offer extended life and compatibility with certain hearing aid models.
- Battery Sizes:
Hearing aid batteries come in various sizes, indicated by color-coded tabs or numbers:
Size 10 (Yellow)
Size 13 (Orange)
Size 312 (Brown)
Size 675 (Blue)
- Battery Life:
The lifespan of a hearing aid battery varies based on its size and the power requirements of the hearing aid.
Generally, smaller batteries (size 10) last around 3-7 days, while larger ones (size 675) can last up to 2 weeks.
- Handling and Storage:
Wash your hands before handling hearing aid batteries to prevent oil and debris transfer.
Store batteries in a cool, dry place, and avoid carrying them loose in pockets or bags.
- Inserting Batteries:
Remove the tab from the battery only when ready to use.
Allow the battery to “breathe” for a few minutes after removing the tab to activate it before inserting it into the hearing aid.
- Battery-Changing Routine:
Change batteries in a well-lit area, preferably over a clean, soft surface to prevent loss.
Familiarize yourself with the correct polarity when inserting the battery into the hearing aid.
- Indicator Tones:
Some hearing aids emit low battery warning tones when the battery is running low. Familiarize yourself with your device’s indicators.
- Rechargeable Batteries:
If using rechargeable batteries, follow the manufacturer’s guidelines for charging times and methods.
Rechargeable batteries may require a bit more maintenance, such as conditioning cycles.
- Disposal:
Dispose of hearing aid batteries responsibly, following local regulations.
Consider using recycling programs or drop-off locations for proper disposal.
- Testing Batteries:
If you suspect issues with your hearing aid, test the battery using a battery tester or the battery indicator on your hearing aid.
- Bulk Purchasing:
Buying batteries in bulk can be cost-effective and ensures you always have spares on hand.
- Temperature Considerations:
Extreme temperatures can affect battery performance. Store them away from direct sunlight and heat sources.
- Consulting Your Audiologist:
If you experience frequent battery issues or if the batteries are not lasting as expected, consult your audiologist for guidance.
- Compatibility:
Ensure the hearing aid batteries are compatible with your specific hearing aid model and size requirements.
By following these guidelines, you can maintain optimal performance and longevity of your hearing aid batteries, ensuring a consistent and reliable power source for your hearing aids. Regular communication with your audiologist is valuable for additional guidance on battery care and usage.
