The batteries for the average hearing aid will last anywhere from 3 days to 3 weeks depending on the type of hearing aid, the type of battery and it’s relative capacity, and the amount of time the hearing aid is actually in use and turned on. The unused batteries have a shelf life of about one year.
Treat your batteries with care:
- DO NOT remove the pull-tab on the battery until you are ready to insert it into the hearing aid; they are activated by air when the pull-tab is removed
- When the hearing instrument is not in use, disengage the battery
- When you go to bed, open the battery compartment fully and set the device in a safe place that is convenient but accessible
- Store batteries in a cool, dry place (not in your refrigerator or freezer).
Change your batteries when:
- sounds become distorted or you keep having to turn up the volume
- you hear the small beeping sound that alerts you to a low battery (not on all models)
- you suddenly lose power
Hearing aids batteries lose their power very suddenly so it is a good idea to keep an extra set of batteries handy, especially when you are away from home. Also, try keeping your batteries away from keys, coins, or other metal objects that could cause the batteries to discharge.
Minimize battery drain by:
- turning off your hearing aid (or open the battery door) when you aren’t using it and it is not in your ear
- remove the battery if you won’t be using the hearing aid for an extended period of time
- try not to store the batteries in areas of extreme temperature, either hot or cold
Help your hearing aid by:
- washing your hands thoroughly before changing the batteries as dirt and grease on your fingers can transfer to the battery and then to your hearing aid which may cause damage to the hearing aid
- leaving the battery compartment open at night so any accumulated moisture can escape and not be cause corrosion on the battery which can lead to damage of the hearing aid
- removing dead batteries immediately as a completely discharged battery may swell and be much harder to remove
Are your batteries installed correctly:
- Insert the batteries properly with the + polarity symbol on the battery matching the + polarity symbol on the hearing aid door
- For ease in finding the + polarity and the – polarity you will note that batteries are perfectly flat on one side (the + or positive polarity) and beveled on the other side (the – or negative polarity)
- If your battery door will not close easily, check the batteries…they are probably in upside down
