Ansmann batteries are digital scrap. A waste of money. Self-discharge: always empty. Charger: Microprozesorgesteuertes single channel control, temperature, end voltage and time. After 10 times recharge the batteries are no longer using. In bucket. Charger says Short. Stress over 2 years about, rarely used (spare batteries). Seems to be a self-destruct after time to be built.
Eneloop contrast: Perfectly regarding low self-discharge and promised capacity. Never again Ansmann Mignon Digital 2850 !!! (Shame for a German manufacturer, with such a sham that "Made in Germany" to get in the dirt)
