I went to use my portable alarm clock several weeks ago and found that the new Duracell batteries I installed last year leaked. I checked my other items and found two Minimag flashlights also ruined. These batteries are marked 2030. The batteries in my flashlights downstairs are marked 2031 and they are also leaking. What happened to Duracell? We trusted them for years but never again. We just don't trust them. We have disposed of our other new Duracell batteries and will never purchase any more. BEWARE OF DURACELL BATTERIES.
