Very complete, powerful but complicated

A powerful charger and any option: AA / AAA / USB; NiMH / NiCd; Sector / cigarette lighter; charge / discharge / refresh batteries; identifying defective and non-rechargeable batteries. Only problem: the manual is too complicated to understand for non-experts, so that one does not really know what the difference between the 4 programs available. If, like me, you know nothing, then do not do anything: simply place your batteries and charger will charge them with its default programming.
