Hearing Aid Batteries

Modern hearing aids may be sleek and almost impossible to see, but they still rely on batteries to keep them charged and functional. Today, hearing aid batteries are disposable or rechargeable. During your hearing aid fitting appointment, the audiologist will show you how to change batteries or recharge your batteries. No matter what type of hearing aid battery you need, Big Thicket Hearing Aids & Audiology has you covered.

Rechargeable hearing aid batteries

Many hearing aids use rechargeable batteries. Advances in technology allow hearing aids to operate for longer periods of time with a single charge, making them more convenient for busy lifestyles. If you have dexterity or vision challenges that make it difficult to manipulate small, button-sized objects (like disposable hearing aid batteries), rechargeable varieties may be a more practical choice for you.

The rechargeable hearing aid battery functions similarly to other rechargeable devices. Just place your hearing aids in their docking or charging station, and in a few hours, the batteries will be fully charged. Most people charge their hearing aid batteries overnight while they sleep. In the morning, the battery will be fully charged and ready to power your hearing aids all day long.

Disposable hearing aid batteries

The most common way to power hearing aids is still with disposable batteries. These batteries create a charge when the zinc in the battery is exposed to air. It’s important to change your disposable hearing aid batteries regularly, as hearing aid function decreases as the battery loses its charge. You’ll always want to keep a supply of disposable hearing aid batteries on hand so you are never caught with dead hearing aids.

Shopping for hearing aid batteries is easy. Each battery size is indicated by a color and a number. Just remember the color or number and you’ll remember your hearing aid battery size. Big Thicket Hearing Aids & Audiology carries all disposable hearing aid battery sizes. The most common sizes, battery life and usage are as follows:

  • Yellow: Size 10 lasts three to seven days the smallest battery used by the smallest hearing aids
  • Brown: Size 312 lasts three to 10 days the most common hearing aid battery in the US
  • Orange: Size 13 lasts six to 10 days used in behind-the-ear and in-the-ear hearing aids
  • Blue: Size 675 lasts three to 20 days the largest battery used by the largest hearing aids
