Hearing Aid Batteries

How do I know which battery to use?

Hearing aid batteries are standardized with number and color codes to make it easy to find what you need. The easy-to-remember codes for hearing aid batteries are 675 (Blue), 13 (Orange), 312 (Brown), and 10 (Yellow).


What are the steps for changing a hearing aid battery?

First, remove the tab on the battery before inserting it into the hearing aid.Then, insert the battery correctly with the positive (+) sign facing up.

How long should a battery last?

Hearing aid batteries will typically last about 3-10 days depending on the size of the battery, your model hearing aid, level of hearing loss, and the demands of the location where you use them. The more active your hearing aid is, the more battery power will be used.

So, why don’t they last longer?

Hearing aids perform complex functions to amplify the sound correctly to meet your needs and the varying listening environments you’re in throughout the day. Watch batteries, on the other hand may last years, but require little power to keep ticking. Hearing aids’ complex functioning uses more but think how much more pleasure you get out of being part of the conversation than knowing what time it is.Hearing aids are getting more and more advanced. With all the extra processing power and new features in today’s hearing aids, you can typically get 3-10 days off a single battery. Why is the life of a hearing aid battery so unpredictable, where one battery may last a week, and another just two or three days? Much depends on your amount of hearing aid use, streaming, and how you care for your hearing aids.

But, be sure to open the battery door when the hearing aid is not in use. Doing so will extend the life of the battery and allow the hearing aid to dry out.

Where should I store my hearing aid batteries?

The best place to store hearing aid batteries is right where you store your hearing aid at night, or when you take it out. In a bedside table, or if you have space, in a drawer in your bathroom. That way the batteries will be there when you put your hearing aids in first thing in the morning. Of course you may want to keep spares with you in your hearing aid carrying case, too.

And no, it’s not a good idea to keep batteries in the refrigerator. Condensation and moisture can harm the batteries. Avoid extremes in temperature too. Like most of us, hearing aid batteries like it room temperature.

What are some good battery tips?

  • Store at normal room temperatures.

  • Do not refrigerate.

  • After removing the tab from the battery, let the battery sit for 1-3 minutes before installing it in your hearing aid. This “activation” time allows air to reach the materials inside the battery and activate them.

  • Wash your hands.

    Wash your hands thoroughly before changing batteries. Grease and dirt on the batteries may damage the hearing aid.

  • Remove dead batteries immediately.

    A completely discharged battery may swell and become difficult to remove. Hearing aid batteries that have been used can be collected and given to our office routinely for safe and environmentally friendly disposal. 

  • Invest in a rechargeable battery hearing device.

    Rechargeable hearing aids are now readily available and are a great convenience and alternative to having to change standard batteries frequently. Rechargeable batteries allow you to charge the battery at night and get a full day’s worth of use, up to 35 hours on one charge! Lithium-ion rechargeable batteries never have to be replaced so it’s one less thing to worry about. If you’re interested in this new technology, be sure to ask Dr. Ivory about these convenient options. 

  • Open the battery door at night.

    When you’re not wearing your hearing aid, turn it off or open the battery door to minimize battery drain. 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.

  • Use a hearing aid dehumidifier.

    A hearing aid dehumidifier will help absorb moisture out of your hearing aid and battery. This will allow the battery power to be used more efficiently. The dehumidifier is also a great place to store your hearing aids.
