Today i'm going to show you How to Make 12v Battery Charge

With this charge you can charge any type of 12 v battery even your car battery

It is very necessary in cold days because the battery drains out very quickly. Laptop charger

Dc to Dc Step Down Converter

It's will convert 19 volts from your charger to 14 volts to charge the battery

It'll provide constant voltage and constant current. (very necessary)

It comes with 3 LED indicators (red, blue and green) red show constant current blue show load and green show constant voltage "full charge"

Features

Input voltage range:6-38 VDC (Note: input voltage not exceeding 38V)

Output voltage range:1.25-36VDC adjustable

Output current: 0-5A

Output power: 75W

High efficiency up to 96%

Built in thermal shutdown function

Built in current limit function

Built in output short protection function

Follow the steps

Cut down the jack of the adapter

Remove the outer shield with a blade (Carefully)

You'll see 2 wire red and black, black is negative and red is positive

You can see the label over the board

The red wire of adapter will go to “IN+” positive of the board (see the image)

The black wire of the adapter will go to “IN-” negative of the board

Tight the screw terminal with a screw driver

Now connect alligator clip

Red alligator clip wire will go to "OUT+" Positive of the Board (see the image)

Black alligator clip wire will go to “OUT-” Negative of the Board

Now you need a multi-meter to set it up

Plug the power to the adapter

Connect the black alligator clip to negative lead of multimeter and red alligator clip to positive lead

you can see 2 Potentiometer over the board (see the image)

The first one is voltage and the second one is current

Now select the DC voltage reading on your multi-meter and turn the Potentiometer with a screw driver until you get 14 volts reading on the multi-meter

Now select the Current Reading on your multi-meter and turn the second Potentiometer with a screw driver until you get 2 amps reading on the multi-meter (you can go up to 5 amps all it depends upon the battery capacity if you have a bigger battery "like a car battery you can go up to 5 amps"
