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. When the battery voltage reduces down to a set point. The LED will bright immediately. Look: in the circuit.
How to Set up the above explained battery status indicator Circuit. It's pretty simple. Apply the full-charge voltage level across the point indicated "to battery positive" and ground. Now adjust the preset such that the last LED just illuminates at that voltage level.
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 simple 12V battery status indicator is a circuit that shows the battery state only by flashing LEDs. For example, if out of 10 six LEDs are glowing it means 60 percent of the battery power is left. When the battery is fully charged the circuit LEDs will turn on, and the LEDs will turn off one by one as the battery runs down.
In this article I have explained a simple low battery indicator circuit using the IC 555 and a few resistors only. Many electronic circuits such as emergency lights, battery chargers, UPS systems, flashlights etc essentially require a low battery indication feature in order to avoid over discharge of the involved battery.
