Hearing aid batteries come in four sizes — numbered and colored universally. The battery size you need will depend on the hearing aid you get. If you don't know the size of your battery, let us know the color of the tab. You can contact our office directly to order more batteries.
Remove the tab when you’re ready to use your new batteries
Hearing aid batteries have a protective tab, which covers the tiny holes on the top of the battery. As hearing aids use unique batteries, known as zinc-air batteries, it’s wise to remove the tab at the last moment. This tab acts as a shield, and once it is taken away, air will enter the battery, activating the zinc. The battery will then spring to life and the power will start to drain immediately.
Take the tab off and wait 5 minutes
Remove the tab from the battery and let it sit for about 5 minutes before placing it in the hearing aid. This will ensure that the battery is fully activated before you start using your hearing aids. Doing this can extend the lifespan by up to 72 hours.
Useful hearing aid battery care tips
- Store hearing aid batteries at normal room temperatures.
- Do not refrigerate.
- Wash your hands thoroughly before changing batteries. Grease and dirt on the batteries may damage the hearing aid.
- Leave the battery compartment of your hearing aid open at night so moisture can escape. Doing so will keep the battery from corroding and damaging the hearing aid.
- Remove dead batteries immediately. A completely discharged battery may swell and become difficult to remove.
- Hearing aid batteries often lose power very suddenly, so it's smart to carry an extra set of batteries with you at all times.
- To protect against discharging your backup batteries, keep them away from coins, keys or other metal objects.
Rechargeable Batteries are becoming the most popular option in hearing aids. We recommend that you bring your charger and hearing aids to your appointment. Your charger is an important part of your hearing aid system. At your appointment, your hearing professional may check the overall functionality of your charger and rechargeable hearing aids.
Useful Rechargeable hearing aid battery care tips

- Do not expose to excess heat, i.e., do not store on a windowsill or in a hot car.
- If you choose to use an electronic drying system, please check with your hearing professional that the temperature does not exceed 40°C (104°F).
- Regularly inspect your charger and rechargeable hearing aids for debris; gently wipe away using the provided cleaning tool or a dry, soft cloth.
- Do not use water, solvents, or cleaning fluids to clean either your charger or rechargeable hearing aids.
- It is safe to keep your rechargeable hearing aids in your charger after they are fully charged and any time you are not wearing them.
- If you will not be wearing your hearing aids for an extended period of time (i.e., longer than three days), please remove the plug from your charger and your rechargeable hearing aids from the charger ports/posts. You may store them inside the open space within your charger.
