Steer clear of this Ladererät

Possession of a Laderät Accu Power IQ - 128 identical Technoline BC 700. the many options are in my eyes just a nice gimmick 1. the charger does not recognize the current state of charge, the "current battery voltage display" shows just how much power with the Accu loaded. 2.If a man called the Accu in the display as a full after about 10 minutes and again he is inlaying further charged. The full Kapatzität is achieved only with repeated loading. The Ladevogang takes a long time the refresh function (battery-care program) 2-3 days. 3. low to change Accu discharged are recognized as defective (zero), man has them with a simple charger short charging dan they work well in this (Accu Power IQ - 128, Technoline BC 700) again. A charger with this high standard and price, which recognizes funtioniernde niedgig discharged accus as defective or not being able to load dise is scrap. Moreover, it is not able to display how full the Accu is. To check how full the Accu is I have to put it in a battery tester. With demand from the manufacturer
why acktuelle Kapatzität would not appear to me, I was told that this was not possible because this Müster geschen under load. Just wonder how the create simple battery testers and where the device knows how long it needs to load in order to charge the Accu.
