Another option for connecting the power supply to the electrical device is to use a substitute or dummy battery. This is anything that takes the shape of the battery and fits in the battery housing, but is used to connect the power supply to the terminals of the battery connectors on the device.
You could use a power supply with a higher voltage than the battery, both the battery and the power supply have their own diode feeding the Arduino. As long as the mains are good the higher voltage will block the current from the battery. When the mains fail the battery will have a higher voltage and provide power through its diode.
This is a charging method where batteries are charged with a constant current from beginning to end. A standard switching power supply is a constant voltage power supply, so it monitors fluctuations in output voltages, inputs the results in the control circuit, and executes constant voltage controlling also known as feedback controlling.
With mains present, the DC supply will maintain/charge the battery and power connected peripherals at the same time. You need to regulate the DC supply output voltage to match the battery maintenance-charge level (about 13.7V). At this level, you can leave it connected/powered at all times. Switchover is instant as this is a hot standby connection.
This toy just sits on the desk, so it’s a good candidate to modify to accept a DC power supply instead of batteries. This idea is not well suited to something like an R.C. Car, but in a pinch, you can use it on the remote control for your TV. Wall outlet power is generally alternating current, or ‘AC’.
If I replace my batteries with a power supply of equal voltage, then the current in the system also stays the same. This project uses this relationship to replace Voltage, V supplied by a battery with voltage supplied by a DC power supply – nothing else is changed.
An AC to DC power supply can change AC wall power to DC power. Many common devices that have batteries (laptops, smart phones, etc) only accept DC power. They use a AC to DC …

This will ensure that the converter can handle the power output of the battery and provide a stable power supply for your devices. Safety and Preparation. Before you begin …
When the laptop is connected to the AC mains power supply, the voltage presented by that unit is provided to both the internal switching power supplies AND the internal battery charger unit. The battery will have FET …
This leads to issues of toxic fumes (vented battery), pressure buildup (sealed battery) and electrolyte loss. So watch the amount of charge delivered (current x charge time = …
Bring the power supply to the store if the troubleshooting confirms it is not working. Bringing the power supply to the store will ensure you that you purchase the right model. You can also …
