The batteries are to have 2850 mAh, which I never achieved. I have a very expensive battery charger, which can measure the discharge capacity. The best thing I could ever rausholen were 2600 mAh and only with a battery. The average of new battery is only 2500 mAh with me. After one month, the capacity decreases is less monthly. After each charging and discharging capacity decreases slightly. So after 100 charge and discharge cycles, the capacity has fallen below 2000 mAh with me, which decreases restive. 'm A bit disappointed, because I can go wrong when loading anything because my charger will cost about 100 and that will prevent overweight. To bring the battery back to about 2000 mAh I have not yet succeeded, although it is an extra-charge program. I've done better experience with other Panasonic batteries which, although located somewhat lower in the capacity from the beginning, but you will lose even after 100 charging and discharging cycles hardly at capacity. As I said everyone has to make his experiences themselves.
