When the storage battery is connected to the output terminals 9 and 10, the control circuit 11 does not connect. It is detected and the discharge circuit 12 is turned on for a certain period of time to discharge the storage battery. After that, the voltage of the storage battery is measured by the control circuit 11 via the A / D converter 13, and the presence or absence of the remaining capacity is determined from the measured value. Then, when the remaining capacity of the storage battery is empty, the control circuit 11 performs super-quick charging with a large current, and when the remaining capacity remains, the current is reduced to perform rapid charging. This operation will be described with reference to FIGS. 1 and 2.

リクル充電（ステップ107）とする。Then, the transistor 14 of the discharge circuit 12 is turned off (step 104), from the plurality of current setting values preset based on the measured voltage, a voltage lower than the nominal voltage of the storage battery with respect to the remaining capacity of the storage battery. It is selected as an appropriate set value (step 105). Since the charger 2 in this embodiment is a charger for a nominal voltage 1.2V nickel-cadmium battery, the reference voltage for determining the remaining capacity is set to 1.1V. That is, when the voltage measured in step 105 is 1.1 V or higher, it is determined that the storage battery has a remaining capacity, and when it is lower than 1.1 V, the capacity is determined to be substantially zero. The control circuit 11 can control the charger current by setting plural kinds of duty ratios of the switching element 6, and in this embodiment, a large current for ultra-quick charging and a current for rapid charging with a charging time of about 1 hour. The values and are set. Then, if it is determined in step 105 that the remaining capacity is substantially zero, the battery is charged with a large current for ultra-quick charging (step 106), and the timer function of the clock built in the control circuit 11 causes, for example, 10 minutes. The charging current is reduced after the set time, and charging is stopped after 20 minutes. After that, trickle charging (step 107) is performed to supplement self-discharge with a small current until the storage battery is removed.

8). Then, after that, the process shifts to trickle charging (step 107) as in the case of ending the super quick charging.
