Holds like a battery should last; p

After my original battery inexplicably from one moment was no longer on the other, I had actually been looking after an original battery. When I saw the price, but then I decided to bring another and ended up, because of the positive reviews, the Ansmann battery. It goes without problems and has even been loaded when I unpacked it. Against my fear that he does not last long, he does it anyway. Whether it holds less or more than the original battery, but I can not say. Previously he fulfilled his service to my satisfaction and hopefully this will do more than my Casio battery)
