Hi
thanks for input , i checked my chargers ones more and found that if they are Connected to the batteries for some time after they are finished (its enough With maybe 10-15 min) the batteries has dropped 0,2-0,4V som if I disconnect when they are finnished I got 41,98 on battery and got 42,02 on charger so so fare I think they are ok , but I think I start changing them soon any way they are maybe 4-5 years so the have soon done their job.
