quick charging mode non automatically u 8 can control to the charging in the normal charging mode without triggering by the outer trigger signal 13 in one embodiment it is preferable to not enter into the quick charging mode automatically when the micro switch sw 1 i e the control switch 3 a on the operation panel 3 is triggered u 8 has detected the condition that it can enter into the quick charging mode and then the led d 18 of the indicating circuit 7 becomes illuminated to indicate that it can enter into the quick charging mode and at the same time the backlight of the control switch 3 a becomes illuminated accordingly the feedback circuit is controlled by u 8 to charge the battery according to the set quick charging current after the micro switch sw 1 is pressed down during charging the led d 18 is flickering to indicate that it is in the process of quick charging mode and at the same time the backlight of the control switch 3 a is flickering in this mode the real time voltage of j 4 j 5 j 6 and j 7 is detected by u 8 and simultaneously it begins to measure the time and the temperature of the charger per se is detected by u 8 via r 75 and it turns into the normal charging mode automatically under the abnormal condition.
