Had the battery only sporadically and in use. Surprised that I, when I raushole again, again have to charge the batteries every time. But now that I wanted to use in alternation with other regularly, it strikes me that they apparently discharged within a short time itself. These experiences are reflected in the other reviews here contradict. Too bad for me that I now can not complain, almost 16 euros for the garbage. In other batteries, such as cheap batteries that already a few years are partly in use, there no problems.
