These batteries are the advantage of not losing load is therefore ideal for me that sometimes leaves the camera in a corner for 2 to 3 weeks and the spring because it is essential to take a picture of an event. The load remains very suddenly with even more photo batteries are made over a period of several weeks. Warning batteries are certified mini 2000 mAh on the body of the stack so the 2500 is not guaranteed. My charger shows the battery capacity and some even go up to 3000 mAh lowest being 2430 mAh
For me this type of battery go completely obsolette conventional rechargeable batteries. A must-have with a smart charger.
