It is very well made and provides the functions Charge, Discharge, Refresh and Test, all at either 200,500 or 700 mAh charging current.
Very useful is the test function, which allows to measure the capacity of the battery. Here, the battery is only fully charged, then slowly discharged and then recharged. At the end, the capacity is displayed digitally in mAh. This process is also a makeover for the battery.
After my battery quite a long lay unused in the closet, I was able to separate the wheat from the chaff. Tip: Poor battery test twice, in part, the battery performance increases significantly after refreshing.
However, a major disadvantage to be mentioned. The Elektronic the device seems the remaining battery level measured before the battery is ever charged. This results in deep discharged batteries mean that this is not recognized and therefore can not be loaded. Here the battery for one hour in a classic charger must therefore only be plugged in, which expresses pure power unconditionally. Ergo: only limited to use as the sole charger. Therefore, a star deduction.
