Battery level indicator indicates battery status only by bright LEDs. For example, six LEDs are bright means that 60% battery capacity remains. This article explains how to design the battery level indicator. You can use this circuit to check the car battery or the inverter. So by using this circuit, we can increase the battery life.
This circuit is designed based on lm3914 IC (integrated chip). This IC is LED Spot / Bar Display Driver.

Battery level indicator Circuit principle:

The heart of this battery level indicator circuit is ....etc

At many situations we need to display the amount of battery charge through some kind of indication methods like LED dot display or LED bar display. Here CG comes with a battery charge indicator circuit using LED dot display. This battery power level indicator circuit is build around LM3914 IC. It is able to sense voltage levels and is capable to drive a display of 10 LEDs in dot mode or bar mode.
We have already posted a temperature level sensor using this same IC (LM3914). This can also be used as a low battery voltage indicator circuit as it ....etc

Battery Tester Project Using LM3914 IC
This objective of this project is to design and build a battery tester that is able to test various types of dry cell and rechargable battery with a voltage of less than 2V. Configured as a bar graph battery level indicator, the LM3914 IC from National Semiconductor senses the voltage levels of the battery under test and drives the 10 LEDs to ON or OFF based on the voltage that is detected. The current driving the LEDs is regulated by using the external resistor R1 and hence limiting resistors are not req ....etc
