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.
How do I change the power supply voltage?
Connect an adjustable power supply. Set the voltage of the adjustable power supply to 14.4V. Remove the battery and the transformer and connect the power supply in the place of the battery.
