T2, T4, T6, T8 and the relevant accessories constitute a constant circuit, the charge current is 50mA and 120mA.As soon as swtich K is closed, the charge current will turn to be 50mA; and if K is disconnected, the charge current will turn to be 120mA. Triode T1, T3, T5 and T7 and the rellevant accessories constitute a detection citcuit that is in a charge state. Potentiometer W is used to set to charge voltage. When it is fully charged, the battery will turn into a trickle maintain state. Trickle is set about 9mA by the resistances R4, R7,R10 and R13.
