    We know there was a lot of information to take in when you first got your hearing aids. So we have created many resources for you to access to help you along the way. Here is a quick summary of the regular maintenance activities that you will need to perform to keep your hearing aids in the best shape possible. You can also visit our YouTube page to some video tutorials that allow you to follow along as you clean and maintain your hearing aids.

    But if you ever need to just talk to someone, please do not hesitate to give us a shout.

    Changing Your Batteries

    If you are using zinc air batteries, please remember that when you take the tab off the batteries, they will begin to lose their charge. This type of battery will typically last you anywhere from 3-7 days.

    If you are hearing a consistent beeping sound from your hearing aids, that means it’s time to change your batteries.

    If you are using rechargeable batteries, please remember to charge your hearing aids every night. After a full charge your hearing aids should be able to last you for about 20 hours.


    Please clean your hearing aids every night before you go to sleep. To do this you will want to use one of the wipes we provided you during your fitting appointment. These wipes are specially formulated to remove residue and wax from your aids without harming them. Use one wipe and clean all the exterior surfaces of your hearing aids.

    Wax Guards

    The wax guards on your hearing aids are used to keep wax from entering the receivers of your hearing aids. You will want to change these once a week or as often as needed. To change these, you will need to remove the dome of your hearing aids. Once that is done, get a new wax guard tool and use the empty side to remove the guard on your hearing aids. Then turn the tool over and insert a new wax guard into the same hole.


    It is important that you wear your hearing aids all the time; but when it’s time to go to bed, make sure that you clean the aids and open the battery door before putting them away for the night. If you have rechargeable hearing aids, please clean them before storing them in the recharging case.
