How to replace a small power supply with a large battery

This Instructable will show you how to work around a proprietary or a non-existent power connector by making a battery substitute power connector that will allow an external power source to be used.

Should you replace batteries with a power supply?

Check the polarity of your batteries and power supply to ensure they match. There will be more on this in a later step. Before replacing batteries with a power supply, consider where the device or toy is used. Will it be sitting on a desk or near the bathtub? Would your kids put it in the bathtub?

Can you put a smaller battery in a ups?

Put a smaller capacity battery in than required and you could potentially over-current it. The UPS will discharge the battery until the terminal voltage drops below about 1.8V. A battery with more capacity will take longer to discharge. Going from 7Ah to 9Ah, for example will give approximately 22% more operational discharge time.

Can I use a DC power supply instead of a battery?

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’.

What happens if you replace a battery with a DC power supply?

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.

What is the difference between a battery and a power supply?

A battery is able to supply that current, while a typical power supply with overcurrent protecton may latch or enter hiccup mode, from which it cant escape. First of all you need to determine the nominal motor current and the maximum current. The maximum current flows when the motor is mechanically overloaded.

How do I make a battery substitute power connector?

Replacing a 12v battery (model A23) with power pack

Or your power supply is a unregulated/badly regulated supply. Since the caps blew, this might be the case. Caps normally blow because of high voltage. Test them first, if the 12v 600 mA is 12v without a load, try connecting it to a remote with a 100Ω resistor in series. This should limit it somewhere between 120mA to 10mA draw (depending on how much voltage the resistor drops).

Replace a battery with a power supply

Replacing a battery from a battery-operated equipment with a power supply can be tricky. Especially when the equipment uses an electric motor. The problem is that an electric motor can draw very large startup current - it can be as 10-20 times the nominal for a couple of seconds.
