Otherwise, the charger is properly, the batteries are never overloaded (when they are fully charged), even old energy bar never too warm and thus spared. There are many chargers which niederbrutzeln the batteries literally, not so with this unit.
The premature end of charge is a software problem. Although the harm the batteries, but that's still stupid, if not always the entire capacity of the battery is used.
I can modify the device with Accu Select (new software, new CPU) and after the modification, it is probably one of the best chargers on the market. The base is thus itself very well.
Due to the sometimes uninspired full early messages of the unmodified instrument only two stars.
