I reciently bought two Duracell batteries for my Cybershot DSC-P50 camera. The first one failed to charge in the camera, would not turn on, nada. Sony InfoLithium battery works fine. I bought a second Duracell battery (I had thrown out the packaging on the first one) and it too failed to charge. Two duracell batteries, neither one will charge in the camera. Duracell's support is non-existant, and Sony says they will not support third party makers. That leaves you guys. Is there something I might be missing as to why I can't charge these batteries? Thanks much for your help!
