The charger is advertised as "automatic battery charger with microprocessor", which remains a mystery, which is apparently hidden in the depths of the equipment technology. First implies these characteristics that the charging automatically optimally runs more or less under appropriate safety standards. Unfortunately, far from it, which is unfortunately only from the operating instructions can be seen (a little one feels here already verschaukelt). So the user has to select the battery capacity even before the charger the charge current "independently" selected. The biggest deficiency is well but that the device has a fully charged battery will not "self" recognizes - the user is stopped "they clamp the Netztspannung off when the battery is recharged" (Hello microprocessor control, what are you doing anyway?). So even the whereabouts of the charger to the battery and automatic switching on a trickle charge state are non-existent. For the good reputation of GYS hardly explainable. And also the SOS-recovery function is only found in the larger models of Batium (15/12 and 15/24). Also, as it is with the protection of vehicle electronics during charging when installed, the device developers are reserved. Overall, for a device in which the charge must constantly monitor itself, unacceptably expensive!
