They are now after the first charging for approximately four weeks in my digital camera. I've made targeted about 100 photos with flash. In addition, the camera has been turned on and off many times, images were viewed on the display, deleted or transferred to the PC. It is just amazing: the camera still shows the full capacity of. The processing of these batteries is simply impeccable. I've tested many other batteries in my digital camera. Even rechargeable batteries with a capacity of 2950mAh show after a few photos to no longer the full capacity and at the latest after 50-70 shots they need to be recharged or replaced. Although I put a very high quality charger for charging the battery. For these reasons, I have believed that the camera simply a "power-hungry" and it does not work otherwise. The batteries from Varta outperform but far all my expectations. These batteries are recommended without restriction.
