Hearing Aid Batteries
Your hearing aids are powered by small, but powerful batteries. They provide your hearing aids with a steady stream of power. When the power starts to wane, your hearing aids won’t perform properly, and you may notice problems controlling the volume and other functions.
Don’t get caught without fresh batteries. Stop in one of our convenient Ears 2 Hear locations and shop for batteries before you need them. Ears 2 Hear carries a full line of replaceable and rechargeable batteries.
How long do hearing aid batteries last?

Getting the most from your hearing aid batteries
Hearing aid batteries use zinc air technology to produce power. To get the most life out of your battery, be sure new batteries are exposed to air. Simply remove the sticker from the new battery and allow it to sit, exposed to the air for 5 minutes before closing the battery door to your hearing aid. When storing your hearing aids for the night, be sure to keep the battery door open as well.
Signia, Sonic and Starkey brands offer models that utilize rechargeable batteries. This eliminates the hassle of frequently purchasing batteries and is a great option for people with vision and dexterity issues that make changing batteries difficult. Each evening just place your hearing aids in their charging station and when you awake in the morning they are ready to go. Ask your Ears 2 Hear Hearing Aid Specialist if rechargeable batteries are right for you.
Storing hearing aid batteries
You always want to have extra batteries on hand. Store spare hearing aid batteries at room temperature. Contrary to popular belief, refrigeration is not necessary. Don’t store your batteries next to keys or in a drawer with coins. Contact with metal can short the battery.
