How to Make Simple 12 Volt Battery Level Indicator Circuit?

[@marian20012]

this is nice but 12 volts battery wouldn't fall under 11 volts, otherwise it's broken.

[@markae0]

lead-acid 12 volt batteries should not get too low yes

[@AhangarRashid]

Useful

[@sushmitshetty8926]

Namaste🙏...which software did you use for analysis --proteus 8 Professional..?

[@CallousCoder]

This is a battery wasting design, because the LEDs will all light up and drain the battery. And 4 LEDs around 10mA is 40mA/H that you initially just waste. But it’s a great academic teaching video though.

[@markae0]

It needs a momentary switch instead of a full on/off switch is all.

Nice

Thank you so much 😊

[@ryanraybusoy422]

hi sir good day .. how about 24Vdc supply ? i simply add the numbers of LED and Resistor ? with the same value of resistor ? is that correct ?

[@shastriroopchand1245]

For lithium battery too?

[@paulbonion]

As long as it is 12v

[@TheOleHermit]

The LEDs only respond to voltage levels, regardless of the voltage source. This is not a circuit for charging. It is actually a discharging circuit. As such, a switch should be added to use it for only checking the battery level to protect lithium batteries from discharging too much, unless a charging circuit is constantly being used.

nice :)

👍

May I know what is the software that is used to simulate the LED circuit? Thanks

[@cokeforever]

can't you look at the software window title bar? 😂 it clearly says Proteus 8

if the 12v battery is on 6v it is very bad,... can you do one real useful circuit where 10v is very low for example

[@tools.no.problem]

Change the values of your voltage dividers. (Resistors).

[@tools.no.problem]

This is a simple voltage divider. Great way to introduce voltage dividers. Terrible circuit for battery powered devices. It will kill the battery very quickly.
