How to Make 6V Lead Acid Battery Charger

Hii friend,

Today I am going to make a circuit of 6V Lead acid battery charger without using transformer.

Let's get started,

Take All Components As Shown Below

Components required -

(1.) Polyester capacitor - 105J 250V x1

(2.) pn-junction diode - 1N4007 x4

(5.) LED - 3V x1

(6.) Lead acid battery - 6V x1

(7.) Connecting wires

Solder all components according to the circuit diagram.

Firstly we have to solder 390K resistor to both pin of polyester capacitor as solder in the picture.

Next make a bridge rectifier like as picture.

Next Solder Bridge rectifier to the capacitor as you can see in the picture.

Solder rectifier according to circuit diagram.

Next we have to solder 1K resistor as solder in the picture.

Now we have to solder an LED.

Connect -ve pin of LED to 1K resistor as shown in picture.

Now solder Input power supply wire.

We can give 240V AC (50/60 Hz) Input power supply to the circuit.

Connect Phase wire to capacitor and neutral wire to rectifier as solder in the picture/shown in the diagram.

Now connect battery to the circuit as connected in the picture/circuit diagram.

Next solder +ve of LED to the +ve of Battery.

Give power supply and left it upto 2-3 hours for charging and use this lead acid battery.

NOTE : For constant output DC Power supply connect an Electrolytic capacitor to the Polarity of Battery.We can use capacitor 50V 100uf , 25V 1000uf.

PRECAUTION : This circuit is very dangerous so be careful during the experiment and Don't try to touch circuit when power supply is on.

Thank you
