This charger is a quick charger for NiCD/NiMH batteries. The standard version uses a method called -dU- (Minus DeltaU-) detection to stop charging when the batteries are fully charged. This method is based on the fact that there is a voltage drop in the NiCd/NiMH cells when the batteries are fully charged. This voltage drop is detected when the voltage has dropped a certain percentage from the highest value. In the event that this voltage drop does not occur, the charger has a safety timer that stops charging after a certain period of time to prevent the batteries from being overcharged.
