How to make a battery into a circuit board power supply

We''ll use a 12V power supply to make a battery backup circuit for our first DIY project. When there are power-supply voltages, the load shifts to that main supply as the battery goes into automatic charging mode. However, when there''s no mains supply, the circuit will automatically shift the current load to the battery – a backup method.

How do you Power a battery backup circuit?

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.
