Thanks

Thank you.

You have to join many diods in series to drop such voltage.

You can add.

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😌

@@lovenumerologyspecialist3517 .

Any equal resistor can be used ,in this circuit both the resistor act as voltage divider.

You have to recharge the battery after some time.

Yes you can install charging module but it will be used say once a year if your battery works for a year.

NPN

Load dene k baad bhi Voltage drop nahi hota hai sir.

Try it

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... 😊

​@@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.

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.

The other clock must have run as output is @1.5 v. Please verify the connections.

Yes. Any clock which runs on DC 1.5 volt

Yes, you have to recharge it.

Koi capyster lag Jaye beech me ta ke chalte chalte volage drop na ho।।

Ji ha

Yes you can

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.

3.7 volt 18650 ko pura charge karke dekhiye.

🙂

Dono same value ke hone chahiye.

@@Techat62 Thanks Kya 4.7 K dono use kar sakta hu ?

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.

I installed on 02-05-21. still working properly. It should work for more than a year.

Only 2 months

Sorry, muze idea nahi he. Online search kar ke dekhiye.

LDO kya hai? What's LDO?

Khatam hone par recharge karni padegi

Replace with charged battery and recharge used.

There is a link in description How to recharge Li iron battery? Pl watch it.

Circuit fir se check kare aur resistors bhi check kare.

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.

Mere video me maine 1.47 v measure karke dikhaya he.

Yes

+ve par do diod IN4007 series me laga go. Aap DC buck converter bhi use kar shakte ho.

If it sort due to any reason, replace it.

@@Techat62 will the watch survive?

I installed on 02.05.21 and it is still working without recharging.

battery ko charge krne ke liye ye video dekh lo. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-_QdMkMvSPIM.html

Ghadi me koi problem ho shakta he. Mera abhi bhi sahi chal raha he.

Mushkil se 2 mahine chala

@@jagdishkumarfatherofsushan3473 bro. Mera thik ho gya ... 3.7 v lithium battery new lagaya

@@sanjivtirkey2479 I got installed this system in 2 wallclocks with fully charged lithium batteries. It worked just for 2 months

😊

There may be some issue with clock movement.

Yes.

😐

Right

I also realise it after making this. It stop working after some months.

Maine multimeter se measure karke dikhaya he.

Thank you.
