Q & As: This Week’s Top Selections
Q: What’s a realistic time frame for a rechargeable hearing aid battery to last?
A: Rechargeable silver-zinc batteries last about a year. They are removeable and therefore easily replaced. It is recommended that rechargeable silver-zinc batteries are replaced once a year by a hearing care professional.
Li-ion batteries are sealed within the hearing aid, and are usually removable only by the hearing aid manufacturer. They last approximately 4 to 5 years.
A: When the hearing aids are put on the charger, the charger will check to see what type of battery is in the hearing aid. If the charger detects a disposable zinc air battery, the lights on the charger will turn red. If the charger detects a silver-zinc battery, the lights on the charger will start blinking green; once the battery is fully charged, the lights will turn solid green.
Q: Can my patients overcharge a ZPower battery if they leave it in the charger for too long?
A: The batteries will not overcharge if left in the charger. It is a best practice to put the hearing aids back on the charger when the hearing aids are not being worn during the day. This will keep the hearing aids turned off and the batteries charged. For long-term storage, if batteries will not be used for over 2 weeks, the rechargeable batteries should be removed from the hearing aids and stored in a location where they will not touch each other or other metal objects.
