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

[@jerryfacts9749]

Very useful and interesting info. I like the simplicity of this LED Voltage ladder readout. No logic gates with op-amps. Thanks!

[@CreativeTechos]

Glad it was helpful!

[@veeem3964]

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

[@GujaratiKanudo]

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.

[@CreativeTechos]

Thanks for your suggestion, i will try soon

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!

[@davidfalconer8913]

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™ ........

[@Sgt_Plague]

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?

[@odintree5704]

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.

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.
