Stay away if you liked to use his equipment any longer

The micro batteries of Fa. Duracell have in recent months 3 my equipment damaged or destroyed, with another I could just avoid this. There are devices where the batteries remain usually longer. (2 LED Tachenlampen, an alarm clock, a remote control). Cause seems to be that, after prolonged use (several weeks or months), the batteries are leaking and forms on the battery a kind Krista liner lining, which merges on the device and corroded there, with massive damage to the conductors is produced. This seems to be limited to the AAA micro batteries, because with larger batteries that mark I could not find it.
