Power plan?

A 12 volt power supply and a 12 volt battery pack are used as a power source. Tell me the options for circuits for automatically switching from a power supply to batteries when the first one is turned off.

oh no, it's not so simple if you keep the battery constantly connected so it won't last long, if you use diodes the battery will be half discharged here you need a circuit with periodic discharge and charging, control of the incoming current, etc.

If EXACTLY 12 Volts - then 2 diodes. The mains power is lost - the current will go from the batteries.
If not exactly 12 V - a switching relay powered from the mains.

If you keep the battery pack constantly connected, are there any network conflicts?
