Signs your batteries are dying
The hearing aid may cut in and out, voices may start sounding fuzzy or distorted, you feel you need to turn the hearing aid up or the hearing aid may just die out. Some new hearing aids have a feature where the aid will beep at you to let you know that the batteries are getting low, and will need to be changed soon. If you notice any of these signs replace the battery with a new one. If this solves the problem, then it was the battery that was the problem. Note on the calendar the date on which you replace the battery. When you replace the battery again, always note the date you replace the battery so you can keep track of how long your batteries last. If problems still persist after replacing your battery have it inspected by your Audiologist or hearing aid dealer.
Immediately dispose of or recycle replaced batteries to avoid confusing them with the new battery.
Do not place zinc-air batteries in the refrigerator or freezer, it will not prolong the life of your batteries. Instead, it may cause condensation to plug the little hole on the battery where the air is supposed to circulate, thus, causing your batteries to work inefficiently.
If you have vision problems do not store batteries near medications in order to avoid accidentally ingesting the batteries.
Time Battery Changes
Replace batteries prior to going to important social events especially if you are coming close to end of your battery life. Always keep a spare pair of batteries on hand for emergencies.
