I must give 5 stars because I can not fault the charger until now. The batteries are locked or unloaded and kept on continuing device in full charge. I was able to call my own a charger even prior to purchase of the Ansmann Powerline, but unfortunately realized that the battery is no longer, if they were too deeply discharged. This problem I no longer have the Ansmann Powerline 4 mobile and am therefore completely satisfied.
