Would you believe that the first package I opened and the first battery did not work at all? So far, the rest of the package performed very well. If I get more batteries that did not work in the batches that I ordered, I will let you know. So far I am very satisfy with my order. Do you have a Hearing Aid BatteryTester that you have as a product or know of one that can be purchased? Thank you. Norman
My hearing aid doctor insists that I only buy Rayovac batteries for my hearing aids. Since my hearing is so important to me I would not even try anything else.
Getting this bundle direct is a lot cheaper than the prices at drugstores. The quality seems as good as any other brand or better. I have had occasional duds, but they are not common and the Ray-o-vacs do seem to last a little longer, esp. compared to the generics.
After a rough few months a while ago with bad batteries, Rayocac is back. The were great in replacing the defective batteries with no questions asked. I have been using these batteries for 15+ years and have been very satisfied with their performance. Would not use any other brand.
