The battery lasts as long as the battery, which was also at the camera with me. That should but indeed expect from an original part. One shortcoming is that he could keep quiet any longer. Time-lapse pictures on the go, I'll go with my J2 not more than 90 minutes no matter how many shots I do and how high is the Aufösung. Beautiful would be a slider, which allows you to select whether the battery is full or empty. So you have to stop working with adhesive dots. After the battery has been a while now use is torn and its housing. I saw him but not treated with care infinite.
