In this simple circuit we will see how can we recharge a lead acid Battery used in most of the electronic projects. This project will save yourself from investing in a battery charger and help you to extend your battery life.

The idea came to me when i was ready to replace a battery cell in my alarm clock next to my bed. Even i am using the last 5 years only rechargeable batteries of the most types i considered how many battery cells people around the world throw away in a simple move like that i did now

DC 12V-60V DC Digital Lead Acid Battery Capacity LED Indicator Voltmeter Tester is Lead Acid / Lithium Ion Battery Capacity Indicator in Red color display. It has auto voltage detection and can measure up to 60V.

here we have developed this battery monitor circuit to test the battery charging status. In this circuit we can easily test batteries by connecting it with the circuit. Here some LEDs are used for showing battery status.
