This bar graph LED battery level indicator circuit is based on LM3914 monolithic IC from National Semiconductor that senses the voltage levels of the battery and drives the 10 light emitting diodes based on the voltage level that is detected. Connect an input voltage of 15 volt between the positive and negative poles and adjust the 10K preset until Led 10 lights up. The LED brightness can be adjusted up- or down by choosing a different value for the 3K9 resistor connected at pin 6 and 7. Remove the R2 resistor and connect 15volt to the input (+ and -) and adjust the 10K potentiometer until Led 10 lights up.
Hi, im a newbie at this and i need a monitor for my 4.6V dc battery from my cellullar that now has a different use. Thanx for the circuit,i needed it for a baitboat i made and i want to check the 12v battery i am using.
And what about the potentiometer, is there a way to skip the calibrating part and directly use a resistor instead?
Lead acid batteries creat sulfate crystals during dishcharge and they attach them selves to the plates increasing their resistance and directly reducing their capacity. The simplest way to prevent them from premature death is to get a Proper 4-stage charger, that will charge them properly and keep them full and healthy.
I use it in place of the voltmeter I made to show me solar power input and battery voltage. The circuit was designed without the use of a power supply or a moving coil voltmeter to create a quick battery tester which can test 1.5 V to 15 V battery cells with a two-LED display.
The circuit was designed to create a spare and reserve power source with the use of batteries  during the absence of power from the mains.


The circuit has been designed to produce a battery charger for automobiles that are using 12V batteries only.
The circuit has been designed to construct a practical mechanism that can easily and automatically charge batteries rated at 6 V or 12 V used in automobiles. The circuit was designed to produce an indication before a 12V lead acid battery would reach the discharged state.
The circuit diagram shows a regular charger being powered by an AC input source, intended for charging batteries.

I have a Radio Controlled Boat that I use for fishing and wanted a way of monitoring the battery and this little baby was spot on. The typical lead acid battery which includes the traditional flodded and the various gell types.
I find it is extremely sensitive and that it gives me a good indication of voltage drop, especially on heavy battery loads. It must be noted that utilizing voltage as a fuel gauge function is inaccurate because cells made by different manufacturers produce a slightly different voltage profile.

Import charges previously quoted are subject to change if you increase you maximum bid amount. I am not including the more expotics like Li-on and its different fmilies because they require different charging regiment. Sulfation will appear like a growth on the plates, while overcharging will boil off the electrolyte creating hazardous hydrogen gas. Our website contains Free Collection of Electronics Circuits, PIC microcontroller projects, diagrams, tutorials, cad and PCB design software, vintage vacuum tube archives, hobby designs, datasheets and many schematics.

The item may be a factory second, or a new and unused item with defects.A See the sellera€™s listing for full details and description of any imperfections.
I like that this circuit not only gives me an indication of my battery status but also a visual indication when I am using something that draws a lot of current like a squirrel cage fan.
