In this video i will show you :- 12V 4 Amp Battery Charger With Auto cut off………….. [Over charge protection circuit ]
Simple 12 Volt Automatic Battery Charger Circuit.. This circuit is very simple and you can easily make it at your home……..In this circuit we will use a relay to cut off charging when the battery will be full.
Required components :-
Transistor BC547
Transistor BD140
12V Relay
5K Preset (POT)
Resistor 1K Ohm × 4
Resistor 68K Ohm × 1
Resistor 220 Ohm × 1
Diode 4007 × 1
Zener Diode 3.9V × 1

Very very detailed, thank you.
Nhi ho rha hai please whatsapp no.9799637448 help me ,no call only chat
Nice ,auto cut off hogi lekin low hone per auto on nhi ho rhi hai jab tak supply off kar ke on karte hai please your contact number, whatsapp no.please help me
Excellent keep it up
Superb
Ham bsna sakte OK hay Kay?
You are really a great scientist
The circle has succeeded after suffering Thank you, my friend, you are really a scientist
mains power supply going to a metal case and no earth wire, if anyone makes this please use an earth wire and fasten to the case
Please help me I have implemented the circuit as it is the video but when the experience Relay always works even after changing the values of the resistance What do I do you already work
I like ur video practical and theory at the same time
poxa vida o youtube coloca tanto anuncio que enche o saco
hi if I use 5 v Zinner diode then what should I change
Where's the diagram?
इसको बनाने में टोटल कितने रुपये लगेंगे
Can I charge 6 vol battery with this or I have to change something? Thank
nice video
Tiger Ashi video to
bhaiya Koi Nahi video
Bhai apka bne ma or diagram ma thoda deference ha apna jo video ma bnaya ha same diagram ki photo bhej doo plz bhai
sir circuit diagram plz send karo
Is it ok if I use bd139 transistor instead of bd140?
Simultaneously a 12-0 2amp transformer.
I honoured if you reply.

6volt batwrry charger outo cut kit banana sikhay please
What is the purpose of zener diode 3.9v?
Alam
what about bettery gravity
Good video ji
Good job Tarun, will this be able to charge a 80 aH battery having 12 volt. The battery is used for SUV. Also a 35aH battery. The battery shown by you seems to be small one.
send me one piece . how much ?
Bhai sahab ye auro metic battery charger ka diagram ke sath batana chahiye. Jo video dekhyebhen wo sitebol nehi he.achha se diagram dekhana chahiye thhaa.
sir circuit diagram dedo please
Sir 68k
Aur 68k ohms dono ek hai????
Sir agar mein 68k ohms resistor ki badle koi dusra value resistor lagaun to kya a circuit kam karega???
Agar dusra value resistor lagaun to konsa value resistor lagaun??? Please bataiye.
