Since I had already read different opinions on the Duracell batteries that two packages were placed directly upon receipt in a battery tester. The needle moved, but remained with all batteries significantly in the red zone: empty. A complaint brought this response: "... Can be used for defects by devices in which our batteries, as and mishandling during insertion (short circuit) we are not liable. " The batteries have been inserted into a device. On an opposition has not been answered. Basically, I believe in the quality of Duracell, but not from this source. Have ordered the company Camelion button cells errreichten the way at least the "beginning of the green zone" of the battery tester.
