There are a few exceptions to this rule. Occasionally, there will be a smaller or larger lip on the batteries that will prevent the contacts inside your hearing aid from meeting, thus keeping the instrument from working properly or at all.
If you find that you have purchased the incorrect size batteries or you are having another issue, please bring them to us and we will exchange them for you at no additional charge.
