In November 2011 I had 5 of 9 volts - ordered blocks through Amazon. Expiration date in March 2014. They were intended for use in smoke detectors in the house. Normal keeps such a battery in these devices 2 years, then signaled the alarm that they must be replaced. The first 2 blocks were empty after only 10 months and had to be replaced werden.Die remaining 3 unused I have measured the charge is just above the yellow area - no longer usable. From due durability by 2014. The manufacturer Duracell (Procter & Gamble), which I have asked several times for an opinion, does not consider it necessary that this be äußern.Zur poor quality and even worse service.
