In datasheets current rating for lm317 is 1.5A but in practical Ic gets hot for current above 0.5A with heatsink. Secondly transformer should be 15V and output voltage of circuit should be 14.4V as needed for 2 wheeler battery. Capacitor of 16V will blast and should be 25V.
If you rectify 12V AC into DC, you won't get 12V DC, you will get around 16V DC. The 12V transformer will output the 12V AC only at full load. At no load it could output like 15-18V AC. And that could result in up to 24V DC at the output of the rectifier. A 16V capacitor could explode in that circuit, and even a 25V capacitor is near it's maximum rated voltage. Better use a 35V capacitor.
Thi is auto cut off ? Means over charge protection?please let me know. Or please provide 12 volt from 2.5 or 7amp led acid battery charger with auto cut off.
Would it be possible to build a 12 V to 12 V charger using similar components? I need a way to charge the batteries on my camper trailer using a 30 amp 12 V output from my vehicle trailer hitch. Thank you
I do not really get it at the end, because the LED blinks when the is no battery connected and continues to do that when the battery is connected. could you explain why?
Is there any danger of over charging the battery here? Once the battery is fully charged, will the power supply to the battery be cut off automatically?
Can you please tell me what's the difference between the regulator you were holding and transistor or mosfet. Or just used normal transistor as a regulator?
You need a BMS board, it is not advisable to charge lithium batteries like you do lead ones, you can buy a BMS board for 1-2 $ also a 12.6 volt charger for about 2-3 $. Check Ali-Express.
Will this act as a Trickle Charger and shut off once the 12 Volts are reached?? By the way, Thank You for this Simple Circuit, I know Nothing about Electronics but I've always wanted to Learn and now that I have Time, I want to Learn as Much as I Possibly can and You're making it Fun to both Build and Learn at the same time!! I'm writing this and I'm only at the Start of Your Video where You show the Schematics. Thank You Again for making it Possible for someone like Me to Learn about Electronics in a Fun Learning Atmosphere!! Sincerely, J Q
@@VladoT Thank You for Your Information!! I'm grateful that You Specified the type of Battery because I would have attempted to use this on a Car Battery but obviously with Safety in place!! Thanks again!
You need to add one way diode like 1n4007 between battery and circuit,on positive wire:) bcz you may damage the lm317
Hey bro
Can I use 7812 regulator
@@علىعبداللاحمن Yes, with 2 diodes connected from it's middle pin to the ground.
@@VladoT Thanks bro
@@VladoT why isn't 1diode
Thank you for actually saying words.💯🙏 Most of the idiots on here have 1920's type silent videos. It's annoying
Thx 4 feedback
Idiots you're looking for guidance 😂
A simple and useful electronic circuit.
Yeah,try it

i keep reading you need 14.4 volts to charge a 12 volt battery? Is this true.
Yes,read on car battery instructions
Can you explain the circuit in detail, especially use of allthe components?!
oh yes basic electronic, i like it
Thanks,be safe bro
Hey, what did you spray on it? An what was it you put on it from the bottle? Super clue? Spray adhesive?
I like this, I enjoy simple circuits. How much current is the lm317 able to handle?
1.5A from 1V to 40V
Nice work, why does the LEd flash?
Can we use better parts to make more power?

great video! awesome idea!!
This is geared towards European countries what about American which use 110v?Is there anything that I need to change to make it compatible?
Just the transformer need to work on 110v,everything else its same
Is there any danger of over charging the battery here? Once the battery is fully charged, will the power supply to the battery be cut off automatically?
No
Can you please tell me what's the difference between the regulator you were holding and transistor or mosfet. Or just used normal transistor as a regulator?
Or we call that a regulator, when a transistor is fixed with those resistors to form one set?
nice job! i can charge a battery 1.5v AAA with it?
THANK YOU FOR THE NICE VIDEO
This is with out auto cut ?
It doesn't have auto cut off, but you can add it.
nice bro..this so useful...keet it up...
Thank you,I made it as simple as can be done
if it is not ordinary LED what purpose does it serve at the output?
Hi, i did everything as instructed but my output voltage is 12.5 vdc... i used a bigger rectifie, maybe thats wrong?
On the schematic diagram it's only 2 resistor but on the actual it's 3
mach nay tu dong khong vay anh
LIke, good work
Very good video brother thank you
Can you also make a trickle charger for LA batteries
Awesome👍👍
How many amp is this
Can I add volt Meter board on exit to test voltage all time?
can it be used as Car battery charger ?
Hey, what should I do if I need a lower ampere in the output?
Why the LED is blinking, while there are DC volts across the LED??
Bcz its blinking led not ordinary led
@@Hacktuber ohhhhkkk bro
Indonesia is present visiting each other is beautiful
Great job, i will make same way, thanks
What is the ampere rating of the xformer?
Amazing Thanx you brother 🤔🤔
How many ampere is the transformer?
What is the ampere rating??
Max 1.5 A
nice bro you'r awesome!
How many ampers of transformers???
More amps for faster charging
Is this suitable for charging 100 amp battery?
no, its better for maintaining it though
6 amp charger? I assume
good bro keep it up🖒🖒

Can i charge 18650 series 12 volt battery
No,for lipo battery you need balance charger
You need a BMS board, it is not advisable to charge lithium batteries like you do lead ones, you can buy a BMS board for 1-2 $ also a 12.6 volt charger for about 2-3 $. Check Ali-Express.
Hi What is out Ampere Amh?
I think this bridge rectifier is from Poland because Iskra in polish is spark
Iskra is from Slovenia

Yes, this will trickle charge the battery when full it may stay connected but only for sealed lead-acid batteries (ups batteries).
Bcz we set the voltage on 13.8v, the battery will never go above that voltage
@@VladoT Thank You for Your Information!! I'm grateful that You Specified the type of Battery because I would have attempted to use this on a Car Battery but obviously with Safety in place!! Thanks again!
@@Hacktuber I should have know that the Voltage wouldn't exceed the 13.8 volts, Thanks for getting back to Me, I appreciate Your Time!!
Where is your fuse??
On ac plugs
Iike EU and UK and us I don't think as one unless you add one but you don't need one
Ow!, I missed the explosion...
🤯
Blowing on the solder to cool down quickly creates weaker solder joint.
Some habits are born with me,🤪
@@Hacktuber YEAh!XD
Прям интересно...откуда столько расходников в нынешние времена😄
Good job
Good
12:08= ASMR🤣🤣
That charger can not full charge the battery.
Me gusta. Lo. Veo bien gracias.
Part numbers? Bridge part number? Amperage rating; you say it is simple: you are the only one to see CLEARLY the schematic.
Good one circuit
i need auto cut battery circuit and auto low battery cut off to avoid damage battery and consumer.
Very nice

最大多少安培？
Cool.

No explanations anywhere; where is ground reference? What is stuff in squeeze bottle? Why? Gotta explain shit, dude
Woow
Breaking bad,😂
why you call 'battery' as 'batary'?
We even call it batre
THANKS
HIGH VOLTAGE DANGER TO LIFE IS VERY FATAL
AND VERY DANGEROUS

wah
Low Amps

Thanks for that,yes you are 1

Why you glue solder joints for it's not conducive 🤔🤔🤔🤔🤔😂 maybe heat Shrink them first FFS 😂
That joints are 220 AC voltage,its dangerous to leave naked
