12V Battery Monitor Circuit Using LM3914 by Jati Pamungkas is a document available to read on EtoBox.

This circuit uses an IC LM3914 to monitor the charging process of a 12 volt battery. It indicates the battery charge level through a series of LEDs, with LED 10 lighting when fully charged above 12.65 volts and LED 1 lighting at 11.89 volts when considered empty. The circuit draws less than 10mA of current and can be adapted for specific needs by making minor modifications, such as changing resistor values to adjust LED brightness or connecting pin 9 to use "BAR" display mode instead of the default "DOT" mo
