I am hard of hearing, and I wear a hearing aid. I won’t use anything but a duracell hearing aid battery. The cheap ones don’t work for very long, but a duracell lasts for a long time. If I buy the cheap ones, I have to rplace them more often, which means that I don’t save any money at all. And it seems as if my hearing aid works better when I use duracell batteries. It’s as if the cheap batteries don’t give the hearing aid enough power to function properly.
