Thank you so much for this. My mother was given this tester for all these stupid, dead batteries she buys for her hearing aid. (What a waste of money!) This will save her time from putting them directly into the hearing aid and then in her ear. Even the manufacturer of her tester, which is similar to yours, didn't have any instructions on their website for how to use it. Again, thank you.

Thank you!!
My tester shows batteries as being fully charged but they won't operate in the hearing aid when new batteries do?
