to avoid: booby-traps

Bought 5 of these batteries in August 2012 opening sensors coupled to an intrusion alarm - OK load level at the reception. The batteries were shipped in the US manufacturer's original packaging with "life of 10 years for the ionization smoke detector devices in" + "lasts up to 5x longer than alkaline battery in other devices 9 v "and" use before 2021 ". In early November 2013, contacted the seller in Germany to apply for a commercial gesture because the 5 batteries are already empty. It refused to intervene on the grounds that "the warranty on batteries is only 6 months" after my investment exceeded 42. Conclusion: In my article and seller to avoid.
