Rechargeable Hearing Aids Tips

  • Nightly Charging: Make it a habit to charge your hearing aids every night to ensure they’re always ready.
  • Preserving Battery: If you are not using your hearing aids for an extended period, keep them in their charger.
  • Safe Usage: Avoid using hearing aids while they’re charging to prevent battery damage.
  • Smart Charger Alerts: If you opt for a smart charger, use its app to monitor the charging process.


So, the best charging option aligns with your lifestyle and individual needs. Whether you prioritize convenience, extra features, or portability, there’s a charging solution tailored for you.


What Is the Battery Lifespan for Rechargeable Hearing Aids?


One of the critical considerations when opting for hearing aids with rechargeable batteries is understanding their battery lifespan. In this section, we’ll break down the ins and outs of battery longevity and maintenance to help you make an informed choice.


The battery lifespan for most rechargeable hearing aids typically ranges between 3-5 years. This can vary depending on the brand, model, frequency of use, and individual charging habits. Most batteries can withstand about 1,000 to 2,000 charge cycles. After the typical 4-5 year lifespan, you have options. You can purchase new hearing aids, or some manufacturers offer internal battery replacements.

Types of Batteries


  • Silver-Zinc Batteries: Used primarily by Starkey, silver-zinc batteries take about 4 hours to charge and provide 24 hours of power. These batteries are user-replaceable and last about a year. If you forget to charge, you can swap them out with disposable zinc air batteries.
  • Lithium-Ion Batteries: Favored by brands like Signia and Phonak, these batteries also require around 4 hours to charge for 24-hour use. Unlike silver-zinc batteries, lithium-ion batteries are part of the hearing aid and last about 3-5 years.


Charging to Prolong Battery Life


Neglecting to charge may result in your hearing aids losing power midday. Adhering to a few essential practices is crucial to maximize the lifespan of your rechargeable hearing aid batteries. First, always follow the manufacturer’s guidelines for charging and usage.  Consistently charging your hearing aids overnight is vital. A full charge can take up to 7 hours, though many models require only 3-4 hours.


Second, protect your hearing aids and charger from extreme temperatures and moisture. Third, plug directly into a wall socket for the most effective charge and avoid leaving your hearing aids in an unplugged charger, as this can negatively impact battery life. Lastly, if you’re using a smart charger, regularly check the associated app to ensure your hearing aids are charging as expected.


Understanding your battery options and adopting good charging habits can extend the life of your rechargeable hearing aids. Consult your audiologist to discuss which battery type best suits your lifestyle and needs.


How Should You Care for Hearing Aids with Rechargeable Batteries?


Rechargeable hearing aids offer the convenience of not having to buy and replace batteries constantly. However, they do require some specific care to ensure they function optimally. Here’s a guide on maintaining the two most common rechargeable hearing aid batteries: Lithium-Ion and Silver-Zinc.


Caring for Lithium-Ion Hearing Aid Batteries

  • Charging Habits: Consistently place your hearing aids in the charging station when not in use. Unlike some other battery types, constant charging won’t shorten their lifespan.
  • Safe Storage: If you’re not using your hearing aids for an extended period, simply turn them off and store them in a damage-free zone. Avoid leaving them in an unplugged charging station, as it drains the battery.
  • Charging Protocol: Before charging, ensure the hearing aids are dry and clear of any debris. Charging typically takes 3-4 hours; an indicator light will signal completion.
  • Handling: When removing the hearing aids from the charger, hold them by the casing to avoid damaging the wire connecting to the receiver.


Caring for Silver-Zinc Hearing Aid Batteries

  • Charging Habits: Always use the charging station when your hearing aids are not in use. Constant charging doesn’t deplete Silver-Zinc batteries.
  • Battery Door: Unlike traditional batteries, don’t open the battery door when the hearing aids are not in use. Remove the batteries and store them separately if you cannot charge them.
  • Charging Protocol: Make sure your hearing aids are free from debris and moisture before placing them in the charger. Charging takes about 3-4 hours, indicated by a solid light.
  • Handling: Hold the hearing aid by its casing when removing it from the charging station.


Additional Maintenance Tips for Both

  • Cleaning: Use a soft, dry cloth to wipe the earpieces and earmolds.
  • Emergency Charging: If you’re away from your charging station, turn off the hearing aids and store them in a safe place.
  • Optimal Performance: Never store your hearing aids in an unplugged charger, as it will shorten the battery life.


By following these guidelines, you can extend the lifespan of your hearing aids with rechargeable batteries, ensuring a consistent and effective hearing experience.
