The charger does have 2 LED's, but the show only on whether a AA or AAA battery cell is inserted or (red LED) if a block-battery is inserted. The LED does not go out after the battery is fully charged!
How long you have a battery charging, you can take out the description of multilingual (also in German) is in! For my 2300mAh batteries that are about 20 hours of charging!
I welcome the batteries can be inserted securely by a solid clamping system and not (as with many other devices common) simple springs keep the batteries.
Also, the device has become not worth mentioning hot during charging (even when I had forgotten to put it times to the charging time, and it was a couple of hours too long in the wall socket).
You can charge rechargeable batteries mixed (ie but micro and normal or mixed in the most extreme case, Micro, AA and block. Loads you are 2 normal storage places occupied a block-battery cell.
Compared with devices costing several times this is not one bit worse. Here I find the value for money is extremely good. The matching AA rechargeable batteries from Ansmann convinced me like the charger completely! Absolut top. 1 times loaded to keep them in the Wii Remote more than 1 week. I'm mega happy and glad that I bought the charger (and the battery)!
