Hearing aid


Help ensure reliable hearing aid performance

Your NuEar hearing aids need a steady power supply from a quality hearing aid battery in order to run effectively. Even subtle changes in a battery's output can mean the difference between clear performance and poor volume or noise control.

  • How long do hearing aid batteries typically last?

    A standard hearing aid battery lasts anywhere from 3 to 22 days, depending on the hearing aid type, battery type and capacity, and the amount of hearing aid use.

  • How do I know if I should change batteries?
    • Change your batteries if sounds become distorted or you have to turn up the volume more than usual.
    • Some hearing aids will also make a small beeping sound when the battery is low. Be sure to switch batteries immediately when you hear the alarm.
    • Hearing aid batteries often lose power very suddenly, so it's smart to carry an extra set of batteries with you at all times.
    • To protect against discharging your backup batteries, keep them away from coins, keys or other metal objects.
  • What's with the seal on hearing aid batteries?

    Always purchase unopened battery packages. Make sure the seal on a new battery is unbroken. A hearing aid battery begins to discharge as soon as the protective seal has been removed.

  • Are there ways to minimize battery drain?
    • After removing the tab from the battery, let the battery sit for 3-5 minutes before installing it in your hearing aid. This “activation” 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.
    • If you won't be using the hearing aid for an extended period of time, remove the battery entirely.
    • Avoid storing in extreme temperatures to keep from draining battery power and shortening battery life.
  • What are some good hearing aid battery care tips?
    • Store hearing aid batteries at normal room temperatures.
    • Do not refrigerate.
    • Wash your hands thoroughly before changing batteries. Grease and dirt on the batteries may damage the hearing aid.
    • Leave the battery compartment of your hearing device open at night so moisture can escape. Doing so will keep the battery from corroding and damaging the hearing aid.
    • Remove dead batteries immediately. A completely discharged battery may swell and become difficult to remove.
