Can I use a battery if I'm using a power supply?
When powering it on for the first time, use a power supply if you have one. Limit the current to 3A. This will keep everything from blowing up if something was connected wrong. Once everything is working using the power supply, you can use the battery. I would highly recommend adding a switch in-between your battery and the 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.
Can I use a battery to power a circuit?
Once everything is working using the power supply, you can use the battery. I would highly recommend adding a switch in-between your battery and the circuit.
