This battery backup circuit can be added to surveillance systems like alarms and others to power the circuit during mains failure. The battery backup will immediately take up the load without any delay. The circuit is simple to construct.
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
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.
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.
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.
