How long do hearing aid batteries typically last?

The lifespan of hearing aid batteries depends on several factors, including the type of battery, the specific hearing aid model, the degree of hearing loss, and how frequently the device is used. Here’s a general overview:

• Disposable Zinc-Air Batteries: These are the most common type of hearing aid batteries. They are air-activated, meaning they begin to drain once exposed to air. Depending on their size, these batteries typically last:
  • Size 10 (yellow): 3 to 7 days
  • Size 312 (brown): 3 to 10 days
  • Size 13 (orange): 6 to 14 days
  • Size 675 (blue): 9 to 20 days

  The actual lifespan can vary based on usage patterns, such as the amount of time the hearing aids are worn each day, the use of features like Bluetooth streaming, and the amplification level required for your hearing loss.

• Rechargeable Batteries: Many modern hearing aids come with rechargeable lithium-ion batteries, which are designed to last all day on a single charge. Typically, these batteries will last about 16 to 30 hours per charge, depending on the usage. The batteries themselves usually need to be replaced every 1 to 3 years.

Factors that can influence battery life include the environment (humidity and temperature), the number of hours the hearing aid is used daily, and the use of power-intensive features such as wireless connectivity or noise-canceling technologies.

To maximize the life of your hearing aid batteries, it’s important to turn off your hearing aids when not in use, store them in a cool, dry place, and follow the manufacturer’s guidelines for maintenance.
