I made a low battery cutoff circuit to monitor my 12v lead acid battery using TL431. I followed the circuit diagram shown below. Sorry for the hand-drawn schematic. I am however not satisfied with the outcome, since I understood with my little knowledge of TL431 that it would work better than a regular OpAmp based comparator.

This lower voltage limit depends upon the type of the battery. This simple battery low indicator circuit can be used for 12V batteries to give an indication of the battery voltage falling below the preset value. The indication is in the form of a flickering LED. At the heart of the circuit is voltage comparator IC LM319 (IC1).
Assemble the circuit on a general-purpose PCB and enclose in a suitable cabinet. Mount LED1 and switch S1 on the front side of the case. Connect a 12V battery to check its voltage level. More interesting projects available here. This simple circuit can be used for 12V batteries as battery low indicator.
Rechargeable batteries should not be discharged below a certain voltage level. This lower voltage limit depends upon the type of the battery. This simple battery low indicator circuit can be used for 12V batteries to give an indication of the battery voltage falling below the preset value. The indication is in the form of a flickering LED.
If V is the voltage at which you want the LED to indicate low battery, then, 1.42*V=1+ (R1/R2) Choose appropriate values of R1 and R2. Once you have calculated the values of the two resistors you can go ahead and set up the circuit. I designed this indicator for a robot i'm working on so the 5V comes from the microcontroller (Arduino) output.
Because the battery is run out. These low voltage indicator circuits may helpful for you. If you can know before and change a new one right now. It makes you not have to waste time when using those projects. Is it great? if you have a lot of ways to do it.
The first circuit is the simplest battery indicator circuit. It can apply to an input voltage of 3V to 15V. The LED will begin to light up. we can adjust VR1 to set a level of checking voltage.
