6 FAQs about [Battery dual power switching working principle]
How do I change a battery if I use a mechanical switch?
The easiest thing, if it is allowable, would be to put a diode in series with each battery. Then you could just swap out either battery any time. But you lose some voltage at the diode. If you use a mechanical switch, there will always be some voltage sag right at the moment you change over, because it is break before make switching.
How can I use a line-powered switching power supply instead of a battery?
simulate this circuit – Schematic created using CircuitLab If you always want to use the line-powered switching power supply in preference to the solar-charged battery, then arrange that power supply to put out a little higher voltage than the battery. It doesn't need to be much, even just a few 100 mV would do it.
How do you charge a battery with a Schottky diode?
Another possibility is to connect the battery directly, and the power supply thru a Schottky diode. Arrange the power supply voltage to be the battery float charge voltage after the diode. You can think of the battery as always providing the power, and the power supply charging the battery when on.
