Actually I bought the batteries for applications such as Camera or wildlife camera. After the battery in my clock was empty was the first application, the Energizer used. Unfortunately, the clock no longer (battery voltage under load OK) went to just one month again. Before that and even now it is running uncomplainingly with cheap batteries from grocery stores. OK. As a second chance she came into the outdoor sensor of my thermometer. There will only batteries from brand name manufacturers. The ENERGIZER the outdoor sensor worked at all. Have I caught Monday batteries? A look in the datasheet shows an internal resistance of 60-210mOhm. A comparison measurement Energizer brand manufacturers showed that the internal resistance of the Energizer is higher by a factor of 1.77 than the competitor. Presumably this is the cause of the malfunction. In the wildlife camera (8) the batteries run now but have a monthly problems (100 photos, battery level is displayed even with 100%). Strange, strange ...
