What are the two main types of hearing aid batteries?
The two main types are Zinc-Air Disposable Batteries and Rechargeable Batteries (usually Lithium-ion).
How do I know which size of disposable battery my hearing aid uses?
Zinc-air disposable batteries are color-coded for easy identification: Size 10 (Yellow), Size 312 (Brown), Size 13 (Orange), and Size 675 (Blue).
How do Zinc-Air batteries work?
They are air-activated; removing a small factory-sealed sticker allows oxygen to enter and activate the battery.
What’s the “5-Minute Rule” for disposable batteries?
After removing the protective tab from a new zinc-air battery, wait for 5-7 minutes before inserting it into your hearing aid. This allows the battery to fully absorb oxygen and activate, extending its lifespan.
How should I store unopened hearing aid batteries?
Store unopened battery packs at normal room temperature (ideally 20-25°C) in their original packaging, in a dry place. Avoid extreme temperatures or loose storage with metal objects.
Why should I open the battery door of my hearing aid when not in use?
Opening the battery compartment when not in use (especially overnight) minimizes battery drain and, crucially for Kolkata’s climate, allows any accumulated moisture inside the hearing aid to evaporate, protecting both the battery and internal components.
Is it safe to carry loose batteries in my pocket or purse?
No, avoid loose storage as they might come into contact with metal objects like coins or keys, which can cause them to short-circuit. Always keep them in their original packaging.
How should I dispose of used hearing aid batteries?
Used hearing aid batteries should be disposed of responsibly. Check with CC Saha Ltd. or local Kolkata municipal waste guidelines for proper recycling or disposal points. Never burn batteries.
How often should I charge my rechargeable hearing aids?
It’s recommended to charge your rechargeable hearing aids every night, just like your smartphone, to ensure you start each day with a full charge.
Can I use any charger for my rechargeable hearing aids?
No, always use the specific charger that came with your hearing aids or one recommended by CC Saha Ltd. Using an incompatible charger can damage the batteries or the hearing aids themselves.
Do I need to fully discharge my rechargeable hearing aids before charging them?
No, modern lithium-ion batteries in rechargeable hearing aids do not suffer from the “memory effect.” Topping them up is perfectly fine; you don’t need to fully discharge them before recharging.
What should I do if my rechargeable hearing aids don’t seem to be charging?
First, ensure the charger is plugged in and the power outlet is working. Check that the hearing aids are correctly seated in the charger and clean the charging contacts. If problems persist, bring them to CC Saha Ltd.
How does Kolkata’s humidity affect hearing aid batteries and devices?
Kolkata’s high humidity can significantly impact hearing aids and batteries. Moisture can cause damage and reduce battery life. Using a hearing aid dehumidifier or drying kit nightly is crucial.
Why is regular professional servicing important for battery life?
Regular check-ups and professional cleaning at CC Saha Ltd. can identify potential issues causing excessive battery drain. Clean hearing aids also work more efficiently, reducing power consumption.
