What makes a great battery? Well, in this case, one that allows you to hear things as if you never had a hearing problem in the first place. My hearing is super sharp now thanks to the Duracell hearing aid batteries that I received from this campaign. Before, I never even knew Duracell made hearing aid batteries, but now I know that they do, I won't be going back to store brands anytime soon. With these batteries powering my hearing aid device, it's almost too easy to forget that I ever had any kind of a hearing problem in the first place. Way to go, Duracell--powering your life and mine, and now supercharging my hearing, too, so that life's best little moments will never again be too quiet to pass me by.
