Battery Care Tips to Extend Lifespan

For Disposable Zinc-Air Batteries

Wait Before Inserting: After removing the tab, allow the battery to sit for about 1 minute so it fully activates.
Store Properly: Keep batteries in a cool, dry place—never in the fridge.
Leave the Battery Door Open: At night, open your hearing aid’s battery door to prevent moisture and preserve power.
Keep Everything Dry and Clean: Wipe the battery and compartment with a soft, dry cloth if moisture or dust is present.
Avoid Loose Storage: Don’t store batteries loose in your pocket or bag. Metal contact (like with keys or coins) can cause short circuits. Use the original packaging or a battery case.

For Rechargeable Hearing Aids

Charge Every Night: Get into the habit of placing your aids in the charger overnight for a full day of use.
Avoid Full Discharge: Don’t let rechargeable batteries fully die or sit unused for long periods. Unplug fully charged aids if not in use right away.
Use the Correct Charger: Always use the charger that came with your device. Substituting chargers may damage the battery.
Protect from Moisture: Keep your charger and hearing aids dry. Use a dehumidifier or drying box as needed.
Turn Off When Not in Use: If you won’t be wearing your hearing aids for a while, turn them off or store them in the charging case to maintain battery health.

With proper care and the right battery choice, your hearing aids can perform at their best and last longer, helping you hear clearly and comfortably each day. Let your audiologist know if you have any questions about maintaining or replacing your hearing aid batteries.
