I am the first to complain when a more expensive product, such as the case with Duracell batteries fail to perform, and I have had similar issues as you have had. I am willing to pay more for something, but that extra cost had better provide me with extra service. With little searchin on the web, which is good since I am a poor web surfer, I fould thid web site:

Check it out. Duracell does have a warranty, and they will back up problems caused by their batteries. I am an EMT, and my fire department, as well as many others only use Duracell batteries for things that must work every time, at any time. People's lives depend on it, so although I have had a problem with Duracell batteries, I am going to give them the chance to make it right.
