In this video i'm showing how to make easy and accurate 12 volt battery level indicator circuit using zener diodes, and if you are familiar with zener diodes they work as voltage barrier when used in reverse polarity, and when voltage in circuit reaches more than rated zener voltage, then it pass that excess voltage to another end.
Same method is used in this circuit when voltage crosses the rated zener voltage then excess voltage passes to other end to which led is connected and then led glows and indicates charge level in battery.

Boa noite
Vou faz um desses incrível projeto para a minha parafusadeira. Já que o indicador de carga queimou
Very useful and interesting info. I like the simplicity of this LED Voltage ladder readout. No logic gates with op-amps. Thanks!
Glad it was helpful!
Creative techno
Nice circuit and I built it but to add it to the charger circuit
Please let me know if this level indicator is safe to have it continuously connected to the battery without the push button switch
I have used 1/4 watt zeners and resistors
Awaiting your reply
Good work sir watching from Ghana 🇬🇭
Thanks for watching my friend 🙂
Sir,
Very nice explanations & with ckt diagram .
ALL correct & full fledged one !
Thank
Thanks for watching, don't forget to subscribe for more videos
The idea of using zener diodes is actually pretty smart. good job
Thank-you
ReaDy
Thanks for watching 🙂
आपका यह जनकारी बहुत अच्छा लागा धन्यवाद।
Thanks for watching my friend 🙂
use 9v, 10v, and 11.1v zener for best monitoring and use.
Red=900ohms, yellow 750 ohm and Green 680ohms resistor for leds brightness and safety consumption.
Thanks for your suggestion, i will try soon
Very good and useful, thank you, I will use LEDs of a few millimeters to put everything in a pen or little box... greetings mr.
Nice idea of pen , thanks for watching.
Great that you have added a circuit diagram ! .... the 12 Volt battery charge ( float ) voltage is 14 Volts ( and NEVER higher ! ) , maybe an additional BLUE LED could be fitted with suitable voltage Zener to indicate charger is maintaining the battery at 13.8 to 14 Volts ? ? ...... DAVE™ ........
Вольтметр цифровой китайский поможет😉
Very good information and very useful video...Thank u very much
I really appreciate your videos, they're very informative. Do you have any videos for a battery indicator that is 48V? We have electric utility carts at my job and we cannot tell when they need charge. Thank you.
Thanks for appreciating, currently there is no video for 48v battery, but I'll soon try to upload video for 48v.
Gostei muito obrigado sorocaba são Paulo Brasil
Thanks for watching 🙂
Eu fiz ficou muito bom demais ok

Please do a lead acid battery equalizer project. It's useful for all who use solar especially.
Thank you so much
Thanks for watching 🙂
Cooolest and accurate thanks bro.
Most welcome bro
Thank you for this awesome video, my friend!
Could I ask you what kind of resistors I should is if I were to use a single RGB Led with same zener diode configuration to light each color for each voltage level?
Thank you so much!
It's a great ideaBattery level meter for 18650 battery Would you please upload the video of?
It is already uploaded please find video on my youtube channel
Appears simply & easy sirji.
Thankyou
Thanks for the reply this video I have watched , my question is can we connect to 12 volt 150 Amps batter home inverter .plz answer me
Yes you can
@@CreativeTechos both circuit or the new one ... Plz make a video on that connecting to home inverter with higher Amps like 150 or 200 Amps battery (12 volt ).
You can use zener diode based circuit with higher amps
@@CreativeTechos thank you so much for the clarification , I would be very glad if you made a video on that .
Wonderful circuit bro !
I hope It'll help me to know the voltage level of my batteries thank you!
Thank-you so much
You can use a voltmeter ...
Very good 👍
Thank you! Cheers!
Thank you for the tutorial.
Is the 1/4watt resistors ?
Yes all Resistors used is 1/4w
@@CreativeTechos and the diode zener 1/4 too?
Thangk you...
My pleasure, Thanks for watching my friend 🙂
Thank you Sir!
My pleasure, Thanks for watching my friend 🙂
Great video! If I want to test 6V battery, what zener diode should I choose?
For 6v, video is already on my channel, you may check that out.
Thank you sir ☺️
My pleasure Thanks for watching 😀
@@CreativeTechos sir your Instagram ID
Actually I'm not using much, using fb
Its works with smd led ? How if we using same led colour ? All i know every colour of led has a differen voltage. If we replace the colour this still work ?
can u please list down the item u used in this video thx
Very nice! I want to make this for 8.4 volt (2S lithium ion battery) . Which value should be changed? I mean what will be the values of zener diode and the resistor's. Please help. Thanks in advance😊
Use Zener Diode "8.2 volt & 6.2 volt use resistor upto 1k ohm
Why are the diodes used here instead of connecting the LEDs in series as in your earlier design??
Great work
Thanks for watching 🙂
Good information video 👌👌👌👌♥❤
Thank-you
fica melhor adicionar um Blinking LED + 12v zener, pra indicar 15v em carregamento, trocaria o led de 9v por 8v e o de 8v por 7,5v "ou 6v".
Thanks for watching, thanks for your suggestions👍
Super 👍👍👍
Thanks for watching 🙂
just what I needed :)
Good video Sir
Thanks
Sir 3.7 volt battery level circuit video
czcams.com/video/ABKq4kbZF4U/video.html
good job but... is better to test battery under load.. just place a resistor (of correct power) in parallel with your circuit to have a real test.
Sir pls which is best
The first video or the second?

Can you make one without zener diodes? Thanks
Coba buat indikator baterai 18 volt mr.
Check out New battery level indicator circuit uploaded on my channel.
Good 👍👍👍
Thanks
So, how come you didn’t include the button in the initial wiring presentation? 😢
as far as I know all buttons are attached at the beginning of the positive wire
Last me jo circuit pcb board par banaya hai use sikhao
You can make this on pref board by following circuit diagram
Being kind of new to all this is there a 'parts list' that I can go by? That would be truly awesome!! I want to add a couple of these to my tractor and backup generator!!
Sorry for that I'll update part list with links in description.
Give couple of days
@@CreativeTechos Thank you so much!
I love the innovation 💡
very good!!!
Thanks
Bhai 3.2v battery ka bano👍👍
Super
Thanks
Pode ser feito para 3,6,9 volts?
Yes just, need to be adjusted with zener diodes.
Do you have a video with this but for a 1.5 volt battery
Bro please send the buy link of all these products seperate.
Good.
Thanks
Fuel level indicator banao bro
Kya ye bulb diffuse hai yes or no?
It is not important to use diffused or clear led . You can use any in both
Very good circuit.
I want to see large +high Ampiar thank you . Asala mo alaikum.
Bro please send the buy link of these products
Is this circuit work on a 12 v car battery
Yes
Instead of zener diode what we can you ?
Zener diodes is main component in this circuit.
Sir I want only one to indicate I.e if it is fully charged- only green glow or if half charged -yellow glows if Discharged -red
Can it be possible
Use RGB led with common cathode or anode
Удобный девайс, но для автомобильного акккумулятора хватило бы и двух светодиодов, потому что на 11.5 вольт он уже не заводит автомобиль
9v battery must use zener diode what series bro??
Make it 7.5V, 5V and 3.3V for the zeners.
Plz make led running controler for home
Didn't got you, please mention fully.
@@CreativeTechos led strip light speed controller RGB plz make circuit
Got it, RGB leds strip with Speed control in colour shifting, I'll try to upload ASAP
Is this work on home inverter battery?
Yes
Can use this to motorcycle fuel gauge
How or where can i add a pot or a resistor and the led cause i dont want to to be bright and noticable at night..thief like shiny thing
For 18650 batteries do not have?
Already uploaded on my channel, you may check out
Nice
Bro make this same circuit but its range increase at 14.4v
You mean green led should glow at 14.4v?
@@CreativeTechos yes bro
I'll try to make in new version, Thanks for suggestions 🙂
Ur welcome
Can I ask please, what is a battery meter actually measuring?
I ask because I asked a company I’ve just bought one from whether it was a simple to read voltmeter/ammeter but with a % indicator. But they said it wasn’t.
But your demonstration suggests it is a voltmeter! Or is it to do with ohms?
It has to do with the voltage drop across each LED. LEDs have a posted voltage drop usually around 2 V for red LED, and the other colours can have 3 or 3.5 volt drop. When your battery has too low of a voltage you do not have enough Voltage to light all LEDs. Therefore the LED with the highest Voltage Drop will go out first and then the next one with the highest voltage drop. So you are monitoring voltage. Check your LED voltage drop with your multi meter. Just take your LED (with no power - before you add it to the circuit) and set your meter to the DIODE reading and connect the meter leads across the diode and you will get a reading in volts. This will be the voltage drop for each colour of your LEDs. Remember LED stands for Light Emitting Diode (so it is just a diode). He is using ZENER diodes to accomplish the same thing. You could just use a regular diode to protect the circuit rather than using the zeners to shut the LEDS off.
Is we use 1k resisters
Thanx
Сопротивления надо менять. Слишком сильно горит красный и слишком слабо зелёный.
Hi what the LED volt rating on each one
Red 2.2v, yellow 2.2v & Green 3.2v
@@CreativeTechos thank you very much. That will help very much
Bro please send the buy link of all these products separate

Can you do a video on a battery meter circuit for 3 - 3.7V lithium ion batteries in series for a 12.6V battery. Most videos I have seen are for lead acid batteries in 12V I wish to see this for lithium ion 12V battery. Thank you.
I'll soon upload for 3s 3.7/ 12v lithium battery.
Pls I'd like to know why the lowest is 10volts and not 0 volts
There the lowest will be 11v where the battery is actually empty, and overdraining it will cause battery to get dead, so it should be maintained as 11v empty & 13v full.
Or if you want level indicator to show level below 11v please check out another video on my youtube channel.
Okay thanks
My pleasure 😊
Please 72 volt circuit diagram
It needs to be experiment, to find out the exact values of components.
Nice ur lacture.pls make a ragulater suply circut on 1.5 volt to 24 volts on 10 amps or 1.5 t0 19 volts on 15 amp pls help .

Bro please tell zener diode kitne watt ke hai correct value
You xan use minimum 350mw
Aur maximum
Bro es circuit me tumne kitne watt ke zener diode estemal kiye hai
350mw use kiya hai
Sir, you have not mentioned the watts
They look like 1W zeners to me and standard 1/4W resistors.
Bro in this circuit, how many watts of zener diode which has used in this circuit
350mw zener diodes can be used
Bro thanks but a problem arise that 350mw is not available please tell me website where I purchase it
You can use also greater wattage then this, also components can be easily sourced from ut source
Ye resistor konsi film ke hai
a.metal
b.carbon
All zener diode kitne --mw ke hai
350-500mw
Bro zener diode full details briefly
Please check check diagram, download link is in video description,

Copper wire is necessary
You can use any Wire, It is recommended to assemble it on zero pcb / pref bord.
Thanks
Como puede ser que un circuito tan sensillo tenga tantas vistas XD
De hecho, se podria mejorar para que no muestre todos los leds prendido y solo el apropiado al color/voltaje
Zener🤔 daiode decided The voltage
Yes, zener diode works as voltage barrier till voltage reaches to greater than rated.
And that excess amount pass on to another end that makes led glow.
@@CreativeTechos Mmm Nice Thinking Thank you for the information.
