A nickel hydrogen battery charger with the function of detection of battery capacity having an instant discharge loop coupled to a charging circuit. A rapid detection of the battery capacity is performed by use of the instant voltage level during discharge. It takes only few seconds to determine if the battery capacity lies within the allowable range. No more charging process is necessary when the batteries reach the preset criterion. To the contrary, a charging process is required when they don't reach it. In this way, it is avoidable that the mixed use of parallel/series-connected batteries with different capacities produces reverse flow, thereby resulting in overheating or even exploding risks due to overdischarge of the batteries with larger capacity.
