How to Change Your Hearing Aid’s Batteries

Unless you have rechargeable devices, your hearing aid batteries will need to be changed.

Hearing aid batteries typically can last anywhere from three days to up to a couple of weeks depending on your hearing aid style, how long you wear your hearing aids each day, and if you do a lot of wireless streaming to your hearing aids.

When the batteries begin to get low you will start to hear beeping in your ear to notify you that it is time to replace them.

Follow these easy steps to install new batteries:


Remove the batteries from the package and peel the sticky tabs off them. 

Hearing aid batteries come in five different sizes with universal color coding. Be sure that you have the right battery size before you open the package. Do not peel until you are certain you will use the battery because there is no turning back.


Give the battery a minute or two to activate – batteries need oxygen to fully activate. 

Zinc-air batteries are designed with fine holes and a filter, so your batteries should be exposed to air for 60 seconds prior to installing, to ensure they will have full power in your hearing aids, and last as long as they’re supposed to.


Next, locate the battery door on your hearing aid. 

There’s usually a notch to press or lever to pull, and the compartment will swing open. Remove the old batteries and place the new batteries into the slots with the positive side up. Hearing aid batteries have a smooth, or positive, side; and a raised, or negative, side. The proper placement for the batteries is with the negative side down, so the smooth surface is all you see.  


Simply close the door until it clicks, and you should be all set with your new battery.

If you have installed the batteries correctly, you should be able to close the doors of the battery compartments smoothly and easily. If it seems difficult to close them, check to see if you may have accidentally installed the batteries incorrectly.
