Hearing Aid Batteries

Powerful hearing aids need a reliable source of power. Hearing aids rely on disposable or rechargeable batteries to power their technology.  You never want to be caught without power, and you never want to be caught without batteries for your hearing aids.

During the fitting appointment, your audiologist will cover the type of batteries used by your new devices and teach you how to change the batteries or recharge the batteries. Battery life depends on the style of hearing aid you wear and the features you use.

Rechargeable versus disposable batteries

If you have problems with vision or dexterity or lead an extremely active lifestyle, the hearing health care provider at Clifton Springs Hearing Center may have recommended that you wear devices with rechargeable batteries. They are convenient for people who have trouble handling or seeing small, button-sized batteries and some models can operate for several days with a single charge.  Many hearing aids that utilize rechargeable technology can also be powered by disposable batteries in a pinch. Be sure to ask about this during your fitting appointment.

Disposable batteries use zinc ion technology. When the zinc meets the oxygen in the air, a reaction occurs that creates the electrical charge to power your devices. It’s essential to store your hearing aids at night with the battery door open and the device in the off position. This will help prevent corrosion and lengthen battery life. Always keep a supply of disposable batteries on hand, so you are never caught without fresh batteries.

Battery sizes

Disposable batteries come in different sizes. Each size is color-coded to make buying batteries easy. Hearing aid battery colors and sizes are:

  •  Orange (#13)
  •  Brown (#312)
  • Yellow (#10)
  • Blue (#675)

Extending battery life

Always use the right charging device for your rechargeable batteries. Some devices, like the Resound LiNX Quattro, charge in a special case that doubles as a power pack. Many rechargeable devices include a smartphone app that lets you monitor the battery level. Don’t recharge your batteries if they still have more than 70% charge.

If you use disposable batteries, store them in a dry place. Do not store them in the refrigerator as this may actually decrease battery life. Store away from coins or other metal items. When you aren’t wearing your hearing aids, turn them off. This is the best way to get the most life out of your battery. And, when it’s time to replace the batteries, always wait several minutes between removing the strip on the battery and inserting the battery in your device.
