I use these batteries even for my camera and this they are the optimal solution. Herrkömmliche batteries lose their charge over time. Eneloop batteries but not (or not so much). So one can also times without problems do not use without fear of the camera for a long period that the batteries have discharged. I total of 12 batteries for my camera use (4 Housing / 4 battery grip / 4 flash) are the relative low 2000mA still perfectly adequate. Previously, I had 4 more expensive Ansmann 2850 mA battery, which, however, have now adopted after 2 years, although I have always been very careful about the battery enlehren completely before I booted again. On the whole, I like the battery so as well, because you can rely on them and will not be surprised at once by a teach camera.
