The Battery Tender Digital Voltage Indicator is designed for use on 12v Flooded, AGM and Gel batteries. It displays voltage between 3 to 16 volts. When the button is pushed or initially plugged in it will display the voltage, and has three indicator lights to let you know your batteries condition: Green (Battery Charged: Greater than 12.0v), Yellow (Battery is Low: 11.6 to 12.0v), and Red (Battery is Discharged: Less than 11.6v).

(2) Depending on the voltage your reading, the number you use to divide is decided by the maximum of the actual voltage source you are measuring. As you can see the number is 204.6. This number was created by taking 1023 (the maximum reading of a fully charged battery) and divided by the maximum voltage of the battery you are using. In this case, I used a 5V battery so I used 1023/5 = 204.6. You then use 204.6 to divide by. If you use a 3V source, then 1023/3 = 341. Then you would divide by 341 to display battery voltage ranging from 0V to 3V vice 0V to 5V.

In this project, I will show you how to design a simple Battery Level Indicator Circuit using easily available components. Battery level indicator indicates the status of the battery just by glowing LED’s. For example six LED’s are glowing means battery capacity 60% remains.

This article explains you how design battery level indicator. You can use this circuit to check car battery or inverter. So by using this circuit, we can increase the lifetime of battery.

The heart of this battery level indicator circuit is LM3914 IC. This IC takes input analog voltage and drives 10 LED’s linearly according to the input analog voltage. In this circuit, there is no need of resistors in series with LEDs because the current is regulated by the IC.

In this circuit LED’s (D1-D10) displays the capacity of the battery in either dot mode or display mode. This mode is selected by the external switch sw1 which is connected to 9th pin of IC. 6th and 7th pins of IC are connected to the ground through a resistor. This resistor controls the brightness of LED’s. Here resistor R3 and POT RV1 forms potential divider circuit. Here pot RV1 is used for calibration. There is no need of any external power supply to this circuit.

The circuit is designed to monitor 10V to 15V DC. The circuit will work even if the battery voltage is 3V. The operating voltage of this IC is 3v to 25v DC. Lm3914 drives led’s, LCDs and vacuum fluorescents. The IC contains adjustable reference and accurate 10-steps divider. This IC can also acts as sequencer.

We can also connect different color led’s to indicate the status. Connect D1 to D3 red LED’s which indicates shut down stage of your battery and use D8-D10 green color LED’s which indicates 80 to 100 percentage of the battery and use yellow color for remaining.

With a little modification we can use this circuit to measure other voltage ranges also. For this remove the resistor R2 and connect upper voltage level to the input. Now vary the resistance of Pot RV1 till the D10 LED glows. Now remove upper voltage level at the input and connect lower voltage level. Connect a high value variable resistor in the place of resistor R2 and vary it till the D1 LED glows. Now disconnect the pot, measure the resistance across it and connect resistor of same value in place of R2. Now the circuit is ready to monitor other voltage ranges.

This circuit is most suitable for indicating 12V battery level. In this circuit each led indicates 10 percent battery level. We can extend this circuit to 100 steps by cascading lm3914 IC’s.

The Battery Monitor is a good idea for anyone without a smartphone or who doesn’t mind staying close to their system to keep tabs. This monitor can also work with all sorts of other battery applications, such as golf carts, electric scooters, medical devices, etc.
