How to make a 4Volt / 6Volt Battery Charger

Contents hide

Today, we will show you how to make a “4V/6V battery charger” easily at your home. Battery chargers or rechargers are used to charge a “rechargeable battery” or “secondary cell” by enforcing charge flow through it.

The “charging protocol”, for example, how much voltage or current for to what extent, and what to do when charging is finished relies upon the type and size of the battery being charged.

Working Explanation

Now, we will discuss the circuit operation of the “4V/6V Battery chargers”. In this circuit, we are using a capacitor, diodes, transformer, and alligator clips with wires. A capacitor is of 16V and 220µF. We have also used four 1N4007 diodes. which is a “PN junction rectifier diode”. These sorts of diodes permit the electric flow in one direction which is “unidirectional”. Thus, it very well may be utilized for the “conversion of alternating current to direct current”. The other component is the “transformer”. In this circuit, we are using a “6V transformer” which is transferring electrical energy taken from an AC source to the rest of the circuit.
