General hearing aid battery tips

Although hearing instrument rechargeability has become very common and will possibly in future eliminate the use of hearing aid batteries greatly, we are still using lots and lots of Zinc Air hearing aid batteries. Hearing aids need a steady source of power to produce optimal functionality.

How long does hearing aid batteries last?

Depending on the size of the battery (10, 312, 13 and 675) as well as the type of the hearing aid, degree of hearing loss and the amount of hours used per day, the battery can last anything from 3 – 20 days. Bluetooth connectivity and the amount of hours of streaming can also significantly reduce the battery life of a hearing aid.

Changing Batteries: Depending on how often you use your hearing aids, you may need to change batteries once a week or twice a month. If the following occurs, you should change batteries:

The “low-battery” beep or voice sound comes on, indicating that the battery is getting low and should be changed. Switch to a new set of batteries as soon as you can when you hear this sound.
Sound becomes distorted or you have to turn up the volume on your hearing aid more than normal. (When this happens it might be that your instrument is blocked and tubes needs to be cleaned or replaced or in some cases wax guards should be replaced.

Remember to remove dead batteries since they can swell , become difficult to remove and can damage your hearing aid battery compartment.

Battery sticker/seals: On your new batteries you will find a sticky tab in orange, brown, blue or yellow. These stickers/ seals keep the battery from discharging power, so never remove the seal unless you’re about to use the battery.

Yolande’s battery tips!

It is recommended to let a hearing aid battery breathe for at least 1 minute before inserting it into the instrument.
Open your hearing aid battery compartment when not in use (also good for reducing moisture build-up).
Do not touch the flat part of the battery when removing the sticky tab and inserting it into the hearing aid
Always carry an extra set with you – they are bound to surprise you when you need them most!
Keep spare batteries away from coins, magnets and metal objects
Store batteries at room temperature
Was your hands before changing batteries

Did you know how to check if a hearing aid battery is flat – except with a battery tester?

Simply drop the battery on your desk or flat surface – if it bounces it is probably flat, if it doesn’t bounce you are still good to go!
