Capacity is according to my computer charger as printed 1500 mAh. Why Conrad is as big and fat in 2500 (and beyond very small mWh) it prints beyond me, any other battery manufacturers are its battery capacity in mAh at. So my opinion is fooled by a larger capacity as there really is. Clear are mWh mAh and different things, but the imprint in my opinion almost what, what's going on with me under false advertising. The tension situation is good, but unfortunately the self-discharge also quite high. For my purpose, the batteries very suitable (instruments), but high-current discharges tolerated the batteries unfortunately quite bad and get hot here.
Unless one has a device which Pulls low power and partout only work properly with 1.5V cells, these are the right solution. Otherwise good NiMh batteries, or on demand at the higher voltage level Alkaline batteries the drug of choice.
Not should also be mentioned that the NiZn batteries can be only with a special charger and charge that does not grade is a bargain pricewise. A normal NiMh charger is not enough because, unfortunately, and the cells would destroy!
