I bought 3 of these 4-packs of Varta Mignon Power Batteries at Amazon. Of the 12 batteries a defect was already after the first charge. The other batteries could be distinguished in particular in that they are almost fully discharged within a week. Furthermore swayed the enormous capacity of the batteries. So my second battery pack reached only about 50% of the performance of the first movement. I have complained about the battery at Varta and got it replaced free of charge, however. Not through the power batteries but by the Professional series, yes but some will cost more Based on my experience, these batteries are not worth the money, because they scatter extremely in their performance. Due to the high self-discharge, they are not suitable for cameras and flash. They are only suitable for devices (eg remote control cars) that can operate with permanently charged batteries. If you use the batteries after removal from the charger immediately, everything is fine, but they must not be let stop.
