After the original battery has sometime bloated and I was anyway not particularly impressed by the quality, I got myself a spare battery of Ansmann. As expected: he is better than the original, which has been like over-discharged times itself and then could not be loaded from the original charger. The Ansmann battery, however, work as you would expect from a decent battery. Overflow time I can now make any statements, but after the first two "field operations" I have a good feeling. Can you recommend without hesitation just for the price!
