Hearing aid batteries last anywhere between five and 14 days depending on the above factors. You will know it's time to replace your hearing aid batteries when the aids start beeping. One solution to save money and make batteries last longer is to purchase rechargeable batteries.
After removing the tab from the battery, let the battery sit for 3-5 minutes before installing it in your hearing aid. This âactivationâ time allows air to reach the materials inside the battery and activate them. When you're not wearing your hearing aid, turn it off or open the battery door to minimize battery drain.
