another interesting thing:when i plugged the charger into a socket,why it didnt give me any voltage as it reads "output=DC 15.0v 0.8A"? the current is also close to zero...
but the charger still works for that kind of condition.
instead,for some other chargers,which should output a constant DC,but when i measured the output,it also stayed around a pretty low DC,then the charging died,it couldnt charge any NiMhs,even the one had been charged by that charger before.
can anyone explain this to me??
