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. Then at the output of the battery backup circuit, there is a male DC power connector that can plug into the electronic device that you want to power.
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.
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. The following components are required to make 12V Battery Backup Circuit
Next, a rechargeable battery is connected using a resistor and another diode. The resistor allows the battery to be slowly charged from the power supply, and the diode provides a low resistance path between the battery and the circuit so that it can power the circuit if the voltage of the power supply ever drops too low.
2 x Diode (rated for a higher current than the power supply) Male DC Connector Female DC Connector There are many different kinds of battery backup systems, and the type that you use is largely dependent on what you are powering.
There are three basic types of batteries connection. Click image to enlarge Below is the comprehensive detail about each connection. If we connect the positive (+) terminal of battery to negative (-) and negative to positive terminal as shown in the below fig, then the batteries configuration would be in series. Good to know:
Battery Backup Circuit: A Comprehensive Guide in Making One
A battery backup circuit is a system that automatically switches to a backup battery when the main power source is interrupted or fails. It consists of a primary power source, a backup battery, a charging circuit, and a switching mechanism. The primary goal of a battery backup circuit is to maintain a stable power supply to the connected device ...

Battery Backup
This battery backup circuit switches over to battery power when the main power fails, and I have used this simple circuit for some time and it works well. The main power enters through D1 and the current goes out to power a circuit. When the current comes in through D1 it cannot go through D2 because that diode is in reverse bias mode.
