- Wall clock, Table clock etc are generally running on DC 1.5 volt AA size battery cell. Which drains out after some months and we have to change it. In this video, I will show you how to run these types of clocks (or anything runs on DC 1.5 volt) on rechargeable 18650 3.7 volt Li-Ion battery. You can also use mobile battery instead of 18650. You can Several times recharge and use this battery.
For how to recharge Li-Ion battery, see my video:- • How to make a Lithium ...

Excellent video ..... bt it would have been great if information about the current was told.... 👌👌👌
I could no longer bear to buy batteries for my wall clocks. I will do it for everyone. God bless you ! 🙏
Thank you
Simple. Goal. With diagram. Description of components. I don't understand Hindi but the way you showed ANYONE DOES. Until me ! 😂

10 k sy zada ki bhi use kr sakty h
I heard ...the best way is using diodes. Can you please make a video showing how drop 3.7 to 1.2 or 1.5v?
You have to join many diods in series to drop such voltage.
Sir maine 3.7 v ko 1.5v badl diya but ampere bhi 1.5amp se 0.06amp hogyi mujhe 0.5amp chahiye kaise hoga please reply??
Do we need to put a capacitor between the (+) and (-) of 1.5 dc output as some circuits have it?
You can add.
Mene pichle month 6 May 2021 ko j circuit bnaya tha us din 18650 battery full charge 4.15v thi. Us din aaj tak chal toh thik rhi hai but aaj iska time 15 mint piche ho chuka mtlb iski voltage drain ho chuki hogi. But mene time set kr diya hai. Is hisab se j battery syad 3 se 4 month tak hi work kr payegi jaise ki j circuit kaam kr rha hai. 🙃🙂🙃
Meri ghadi me 5th May se aaj (30th June) tak ekdam sahi chal raha he aur battery ka voltage bhi sahi he. Aap dusari ghadi me try kar ke dekho aur ye ghadi me normal cell dalke dekh lo.
@@Techat62 g apki baat shi hai. Mene is circuit ko ek gifted table Clock me use kiya hai. Is Clock ko use krte hue 6-7 saal ho gye hai pehle isme cell use krta tha tab v j normal wall Clock se v pehle hi cell khtam kr deta tha 5-6 month me hi jab ki wall clock 8-9 month tak chlta tha same cell se. Aajkl cells companies bekar ki battery life de rhi hai mtlb 2-3 month me hi cell drain ho jate hai usi muskil ko door krne k liye mene j circuit bnaya tha and isme 4700uf 25v capistor v lgaya hua hai lakin is table clock me fir vhi problem hai. Bhut jldi drain krta hai batteries ko😌

I have seen this type of circuit in many RUclips videos but not made it. I want to ask will it really work for many years or we have to recharge the battery after some period?
You have to recharge the battery after some time.

How you calculated resistor value?
Plz explain.
Any equal resistor can be used ,in this circuit both the resistor act as voltage divider.

Hi, this simple circuit doesn't give stable 1.5v out put because the reference voltage at the base gradually changes with the dropping battery voltage... Which in turn slows down the clock speed. My modified circuit gives the very stable 1.5v output even if the the battery( li ion /li po / or 18650 type )voltage drops down to 2.5 volts..
Ok. Pl share your modified circuit.
Where's the circuit?
Ok.. Remove the resistor connected between base and ground, replace it with 2v zener.. ( recipe for 2v zener is a secret.)Also change the value of resistor ( between base and supply ) to 10k...That's all. 👍
I fear peoples start copying my circuit and post it on you tube... 😊
ruclips.net/video/XFxWaWBt_Ms/видео.html
@@shirishvasave8002 , Dear Brother, You need not to worry about copying your circuit ! The fact is i myself can't understand ( 2v zener ! ) What do you want to say,. I am now 69years of old and steel experiencing about varieties electronic circuit ! I am telling you about a easy circuit for clock , you can try once . No lithium 18650 needed , so there was no question of clocks voltage ups and down or no need to charge lithium battery. Just take 105 j/k(400v) polyester capacitor , one 220uf 35/,50v electrolytic capacitor, and 5v,1w zener diode! and connect directly 220 volt ! That gentleman make a mistake, in place of 10k half watt resistance he should use 470k quarter watt resistance, out will be shown 180/182 volt , and it it's an appropriate voltage to run any wall clock. An ordinary new battery shows 1.6 volt , so there will be no bad effect with 180v . If you want to know the circuit details, you comment me , i am ready to help you always. A lot of thanks my friend be happy and stay healthy.
Kuch kuch video me 10K Registor aur kuch video me 4.7 k Registor dikha raha hai
Dono ka conversion kya same 1.5 volts hi hoga ?
Plz confirm which one should be better?
Dono same value ke hone chahiye.
@@Techat62 Thanks
Kya 4.7 K dono use kar sakta hu ?
Nice but jab bettry thori down ho gi 4 volt se 3.6 volt Tak e circuit kam bnd kr deta h.2 mnth ke bhad. Agar voltage 1.50 se upar ho skti h batayi ye
Yes, you have to recharge it.
Koi capyster lag Jaye beech me ta ke chalte chalte volage drop na ho।।
We can use LDO to convert 3.7v to 1.5 v
And it occupy less space.LDO consume very low current.please advice.
LDO=Low voltage drop out regulator.
LDO kya hai? What's LDO?
Ingeniero el transistor BC547 es NPN o PNP ?
NPN
I have managed to run a clock by doing this project. By doing the same project the output is 1.47v to 1.53v but the other clock is not running but is running on battery. What shall I do?
The other clock must have run as output is @1.5 v. Please verify the connections.
Bhai sahab , upki video meine dekha ! Our ek watch mechanic hote hue upko ek bat batana chahunga ki up uski out put measure korke dikhayen 1.45/1.46 lekin ea voltage ghari chalne ki liye sahi voltage nohi hai ? up Jo 10k resistance lagaye hai uo sahi nohi hai uovi half watt ki ! Uspor voltage our Kom ho Gaya ! Mera ek suggestion hai ( Mane ya Mane uo depend upon you ,ekbar try to kor lijiye) 10k resistance ki jagah up 2pcs 470k quarter watt lagaye ! Usme out put dikhayga 180 to 183 ! Our uo bilkul ghari ke liye perfect voltage hai? Ek New ordinary battery ka voltage show korta hai 1.6 to 1.62. it's just a suggestion for you , don't take it other sense. I am also a aged person like you 69 years of age. A lot of thanks for your enthusiasm to make video like this which is very much inspired me.
Thanks for your detailed review. I think using other same value two resistor can work. I am not electronic engineer. I do this for my hobby.
Sir how can we use li ion battery for 3V .as some clock uses 3V
Join 2 IN4007 diode in series at 3.7 v battery +ve to get @ 3v.
@@Techat62 Thank you very much for reply sir. Hats off to you.
You are welcome.
Mere out put se 1.o5volt de raha hai kya karu mera battery 3.7 volt 18650 1500mah hai sahi karne ka tarika bataye
3.7 volt 18650 ko pura charge karke dekhiye.
जब बिना लोड के ही 1.4 volt मिल रहे है तो जब लोड देँगे तो वोल्टेज और ड्राप होंगे कुछ समय बाद तो फिर घड़ी नही चलेगी या फिर चलेगी भी तो धीमे ..तो सबसे अच्छा ये होगा कि 1.5 volt की चार्जेबल बैटरी ही ले ली जाए
Load dene k baad bhi Voltage drop nahi hota hai sir.

How could this last long, can you please explain me ?
I installed on 02.05.21. It is still working. You can recharge it.
@@Techat62 I too made this circuit and set it in clock but unfortunately within 10 days Lithium cell drained off.. I think due to parallel connection of resistors it may drained off. Am I right or wrong. Can you please reply ?
Arun, there may be something wrong or some component may be faulty. I installed on 02.05.21 and it is still working.
Li ion battery charge nahi karni padegi?
Khatam hone par recharge karni padegi
Sir mera ya work ni kar raha.output pe bhi same batery k voltage a rahy ha 3.7 help me
Circuit fir se check kare aur resistors bhi check kare.
How long this battery last on a single charge
I installed on 02-05-21. still working properly. It should work for more than a year.

मैने बनाया मगर output 1.28 से 1.30 v आता है
घडी एक हप्तेके बाद रुक जाती है जैसे सेल वीक हो जाता है क्यों ?
बताना please
Haa.
uncle why not 1.5v rechargeable battery instead?
of course you can use 1.5v rechargeable battery but 3.7v Li-Ion 2nd hand battery is easily available from laptop repairing shop or bhangarwala at cheaper cost.

This is a failed experiment and I have also tried on my channel but the clock using this type of circuitary would last only for around two months...😢😢😢
Right
Not lifetime just 2 months life in one charging.
Yes.
Wont be of much use. With time clock shows time ahead of actual time. 😂
😐
My clock become fast 10 min in 24h out come only 1.4v
There may be some issue with clock movement.
What is this ? Stupid idea,
Starting it will work, But as soon slight battery voltage drops, Transistor voltage at base also decrease, result emitter voltage decrease very fast,
I also realise it after making this. It stop working after some months.
Ye video fake he.10k rasister se 1.5 volteg nahi nikalte
Maine multimeter se measure karke dikhaya he.
Bahutt. Bhadhya
Thank you.
