Battery tester for Zinc Air?

Does anyone know if there is a battery tester for Zinc Air batteries?

I was in Radio Shack today and they told me that they didn’t carry a tester for that kind of battery (first time I’ve ever been told that in 4 yrs.) I have two children that have hearing aids and one of them is not old enough to tell me when the aids are beeping because of a low battery. Any ideas? TIA

Go to a Costco hearing aid center and get one, your audiologist, or

I like Good folks. Have helped me alot. :slight_smile:
