Here is a simple battery charger circuit diagram:
Click on the image to enlarge it:


You can see the values of the components used below:

R1: 56 giga ohms resistor
R2: 220 Mega ohms resistor
C1: 105 Kilo pico farad , 250 voltage capacitor
D1: IN 4007 Diode
D2: Light emitting diode indicator
D3 : IN 4007 Diode

If you use the values of the components stated above the circuit can recharge a 3 voltage rechargeable battery , You can change the value of R1 and C1 to get recharge battery of more voltage.
