6 tips for getting the most out of your hearing aid batteries

  1. Hearing aid battery life expectancy
    Batteries can last between three and ten days, depending on your hearing loss, how long you wear your hearing aid for, and the age of the batteries.
  2. The 5-minute rule for hearing aid batteries
    Let the battery rest for five minutes after removing the sticker. This will allow the air to activate the battery, which can expand its life by days.
  3. Hearing aid battery bounce test
    Drop the battery on a table from a height of around 10–15 cm. If the battery bounces several times, you should replace it.
  4. Conserve your hearing aid battery life
    Leave the battery door open when you remove your hearing aids at night.
  5. What should you do with old hearing aid batteries?
    Find your closest battery recycling point.
  6. Storing hearing aid batteries
    Keep your batteries in a dry place at room temperature.
