Hearing Aid Battery Guide

Improving the lifespan of your hearing aid batteries can help you get the best performance out of your devices, and save you time and money. If you’re able to get a few extra days out of each hearing aid battery, that can add up to significant savings over the course of a year. At Hearing, Balance & Speech Center, we want you to get the most out of your investment. So we’ve put together 8 tips to improve the lifespan of your hearing aid batteries.

  1. Store any unopened / unused hearing aid batteries in a safe place and at room temperature - Although you may have heard that storing batteries in a refrigerator prolongs their lifespan, this is not true. Zinc-air batteries and moisture do not mix. Condensation that develops from the refrigerator can cause corrosion. This increases the risk of the battery failing early.
  2. Leave the protective tab in place until you’re ready to use the batteries - Pulling the plastic tab prematurely will activate the battery, causing its power to begin draining.
  3. Open the hearing aid battery door when you’re not using the device - Opening the door to your battery compartment can help reduce corrosion by minimizing moisture build up.
  4. Protect from exposure to moisture - Do not store your hearing aids in the bathroom or near sources of moisture (like a bedside diffusers or humidifiers). Keeping your device ventilated helps to dry out any excess moisture.
  5. Invest in a hearing aid dehumidifier - A dehumidifier is a simple, yet effective, way to eliminate moisture and prolong the lifespan of your hearing aid batteries.
  6. Handle your hearing aid batteries carefully - Rather than inserting a new battery into your device immediately, let it sit exposed to air for a few minutes. Five to ten minutes allows the battery to power up fully and will result in optimal strength. This could potentially extend battery life by up to 3 days.
  7. Buy new batteries - Unopened hearing aid batteries left in their package can last for several years.
  8. Remove batteries if you won’t use your hearing aid for a while - If your device is going to sit unused for a prolonged period of time, remove the batteries. Store them in a room-temperature, dry spot to avoid any leakage into the device.
