How long do hearing aid batteries last?

Standard hearing aid batteries last anywhere from 3 to 22 days, depending on the hearing aid, the battery type and capacity, how often the hearing aid is used, and how much streaming you do.

How do I know if my hearing aid batteries need changing?

Depending on how often you use your hearing aids, you may need to change batteries once a week or twice a month. You should change your hearing aid batteries if either of these occurs:

  • Sound becomes distorted, or you must turn up the volume on your hearing aid more than normal.
  • The “low-battery” beep or voice sound indicates that the battery is getting low and should be changed.

What is the protective seal on hearing aids for?

The small, sticky, colored tab on each battery is also a protective seal. These protective seals keep the battery from discharging power. A hearing aid battery begins to discharge as soon as the seal has been removed — so don’t remove it until you’re ready to use it.

How can I maximize my hearing aid battery's life?

Once you remove the protective seal from a battery, it begins discharging power. However, there are things you can do to help minimize battery drainage:

  • Turn it off or open the battery door when not wearing your hearing aid. Note: you should always open the battery door at night to allow moisture to escape and to help keep the battery from corroding.
  • Take the battery out completely if you aren’t using the hearing aid for an extended period. You can store it in the protective case for your hearing aids.
  • Avoid storing batteries and hearing aids in extreme temperatures, hot or cold, as they can quickly drain battery power and shorten a battery’s lifespan.

Useful 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 aid 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.
  • 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.
