How does a 12V battery backup power supply work?

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.

How do I connect a power supply to a battery backup?

This isn’t a problem if the backup power system is very rarely used. Using the battery backup circuit that I designed, you can plug your power supply into a female DC power connector. This is connected to the battery backup circuit.

How does a battery backup system work?

First, you need a DC power supply. These are very common and come in a variety of voltages and current ratings. The power supply connects to the circuit with a DC power connector. This is then connected to a blocking diode. The blocking diode prevents electricity from the battery backup system from feeding back into the power supply.
