How do you connect a backup battery to a power supply?

We connect the Backup battery 7.5V (AA 1.5Vx5) with D2 in series, and both across the output terminal. The voltage drop across D2 serves to reduce the voltage level of the power supply down to about 7V (6.8V). Also: 8 ways how to converts 12V to 6V Small Uninterruptible Power Supply UPS Circuit When use this with the AC main.

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.
