$begingroup$ The voltage regulator cannot respond instantaneously to changes in power requirements, resulting in a momentary dip in voltage when current demands increase. The capacitors charge to the output voltage level of the regulator, and then supply localized current while the regulator adjusts to meet the demands on the power rail.

You did not say if there was a problem with the equipment plugged into the UPS. Usually you can hear if the UPS is on battery backup. Do you hear that or does the UPS eventually power down if the battery is used? The UPS should have a VA rating (Volt-Amps) which can generally be used to determine the length of time the battery will last.

What a regulator actually does is to smooth out variations in voltage to make a source look more like a battery. In a case like this, you don''t have to worry about the source voltage changing much, so the main advantage of regulation is moot.

Using Autodesk Circuits and a lead-acid battery, you can create a circuit that will act as a variable power supply, outputting a range of voltages from 5V to 20V. After creating the power supply you could drive motors using variable voltage, power microcontrollers, logic circuits, LED strings, analog circuits, and much more.
When powering it on for the first time, use a power supply if you have one. Limit the current to 3A. This will keep everything from blowing up if something was connected wrong. Once everything is working using the power supply, you can use the battery. I would highly recommend adding a switch in-between your battery and the circuit.
After creating the power supply you could drive motors using variable voltage, power microcontrollers, logic circuits, LED strings, analog circuits, and much more. This is a good way to learn how basic electronic components can be put together, like a puzzle, to accomplish a task.
This means they need to be beefier in order to not explode/break. This is similar to why the power brick for your laptop is so big, its handling a lot of power (and also converting from AC to DC). You should now have a working, battery power supply!
