In this tutorial, we are making a circuit of a 12V Battery Backup Power Supply. This circuit will automatically shift the load to the battery in the absence of the main supply. When the mains supply is back the load will shift to the mains supply and the battery will go into charging mode automatically.
But sometimes loses power, it runs out of energy for working as a power outage. We need to use a UPS circuit UPS (Uninterruptible Power Supply) circuit Diagram diagram. Some call the emergency backup battery systems. It can be applied to many applications. When the power goes, the battery can provide backup power automatically.

How do batteries work? A simple introduction
One of the metals wins out and pulls electrons from the other, through the outer circuit—and that flow of electrons from one metal to the other is how a battery powers the circuit. If the two terminals of a battery were made from the same material, there''d be no net flow of electrons and no power would ever be produced. That''s the theory ...
