How To Make a 18v Battery Charger Without Technical Knowledge

 

Today we will learn about how to make an 18v battery charger. Sometimes it happens that the 18v battery of one of our devices is not charged with the internal charger, then we need an external charger. With the help of which our battery can be charged.

 

We are also going to provide you a video in this article. If you are having any problem in making the charger, then you can make the charger by watching our video.

How To Make a 18v Battery Charger

If you have to charge your battery with an external charge then you now have two options.

(1) First you can buy an 18v battery charger from the market. (2) Secondly, you can make an 18v battery charger at home.

 

 

But I will tell you about how to make an 18v battery charger at home. Before this, I will tell you about the components in the charger.


6  Electronic components are used to make 18v battery chargers.

(1) 0-12 volt, 2 Amp Transformer

(2) 220 Volts AC Input

(3) 1N5399 Diode

(4) 33k Resistance

(5) 1 Volt, Led

(6) 25 Volt, 3300uf Capacitor

 

Now you have come to know about the components used in it. Let us now make an 18v battery charger.

Step 1. First, we will add 220 Volts AC Input cable to both the wires of 0-12 volt, 2 Amp Transformer.

 

Step 2. Now we will add a 1N5399 Diode to the first wire of the output of the transformer and a second 1N5399 Diode to the second wire.

Now your 18v battery charge is ready. If you have a multimeter, you can check the voltage of your charger. You will get Proper 18volt in the charger.

 

❤ FAQ ❤
 
Questions. Can you charge an 18v battery with a 12v charger?

Answer. The 18v battery cannot be charged with the 12v charger. If you have to charge 18v battery then the voltage of the charger should be above 18v only then your battery will be charged.

 
 

Questions. Can you charge a 20v battery with a 18v charger?

Answer. The 20v battery cannot be charged with the 18v charger. If you have to charge a 20v battery then the voltage of the charger should be above 20v only then your battery will be charged.

  2. Hey there! I know this is somewhat off topic but I was wondering
    which blog platform are you using for this website?
    I’m getting fed up of WordPress because I’ve had issues with hackers and I’m looking at alternatives for another platform.
    I would be fantastic if you could point me in the direction of a good platform.
