The unit has individually and optimally to load a lot of settings to its batteries. By loading the round cells about chargers (I use the by Voltcraft) there is no external heating of batteries (such as burlap and chargers), and by the very fine adjustment of the value -dV let the battery very gentle and precise load. It can be by means of the charging center determine the quality of batteries and their current state well, what is not possible with most chargers (could so easily tell the difference when NiMh batteries between brand manufacturers and NoName manufacturers)! I therefore used thus far NiMh, NiCd and lead-acid batteries.
Operation via the buttons on the front is a bit cumbersome and therefore recommend control via a PC by means of the USB interface. The software allows the charging center very good use and evaluate.
For someone who wants to optimally charge its batteries and / or want to know the state of his batteries for this device is highly recommended. This has its high price, but you score a lot of value.
